What to Look for in a Hurdy-Gurdy

ARLE LOMMEL · MARCH, 2017

Hurdy-gurdies are complex and expensive instruments. As with most instruments, you can find the range from masterwork to wall hanging. Unfortunately, bad instruments can still set you back hundreds or even thousands of dollars or euros.

My best advice is to have an experienced player look at any instrument you are interested in. However, I recognize this is not always possible, so this document lists features and characteristics you should look for in evaluating a hurdy-gurdy.

It starts with basic features for beginner instruments, and is followed by a list of specific issues that quality instruments should exhibit. It closes with some features you might consider for a “step up” instrument.

If you are looking at an instrument online and cannot determine how well it meets these criteria and the seller cannot or will not provide you with enough information to tell, pass up on the instrument, no matter how attractive it may seem, unless you are prepared to make repairs yourself.

If you are not in a position to try out the instrument yourself, or you do not yet play, ask other players for their opinion of a maker’s work. Unfortunately, there are a few well-intentioned and prolific makers who nevertheless produce marginal instruments, and asking others about their experience will help you steer clear of these makers.

This list should help you see why you should avoid a certain maker of bargain-basement instruments with very low prices seen on eBay. Even a quick glance at the photos this maker provides tells you that they fail to meet even basic requirements for a usable instrument.

Beginner features



When you first look for an instrument, ask yourself the following questions:

What sort of music do you want to play? Unless you want to play music from a specific hurdy-gurdy tradition, you should probably look for a contemporary French-style instrument. Most makers produce this type. The primary modern alternatives are Hungarian-style (called tekerő or tekerőlant) and Galician (zanfona) instruments. If you are interested in historical music, you might consider older styles, like the box-shaped symphony. You may encounter other types, but unless you are looking at diving into those traditions, you will probably find the French-style instruments to be a more versatile option. This document assumes you are looking at either a French or Hungarian instrument, but most of the advice applies to other types as well.

What is your budget? Hurdy-gurdies are expensive instruments. Any instrument you find under $1000 is likely to be an inferior instrument that will only frustrate and limit you in the long run. You are generally better off saving up for a quality instrument or putting a deposit on an instrument and paying it off before delivery. As a rough guideline, basic French-style instruments with six strings from makers in the U.S. and Western Europe are likely to cost around US$3,000. Hungarian-style instruments will be anywhere from US$1,500 to $2,000. Some simpler instruments cost less than these amounts, but if you find a deal that seems to be too good to be true, it probably is.

Are you looking for a new or used instrument? Sometimes you can save money by buying a used hurdy-gurdy, but this approach can be risky. You may be getting a great instrument that someone is moving on from, or you may be paying to take someone else’s problem off their hands. If you buy directly from the maker, you have some assurance that the instrument is set up properly and does not suffer from major problems. In most circumstances (there are exceptions, of course), you should not buy used instruments from eBay or other sources: A lot of would-be players have been burnt taking this approach. Instead, buy directly from the owner and find a way to get some first-hand experience with the instrument before you commit to buying it.

For a beginner instrument, look for the following as the basic features your instrument should have or exceed. If it falls short of these requirements, look for a different instrument.

Three or four strings. One or two chanters and two drones (bass and tenor). More strings are fine, but you should not use them until you are comfortable with the basic strings. The basic French setup has six strings (two melody + four drones). Hungarian instruments have three or four (one or two melody + two drones).

Buzzing bridge (unless you are specifically learning a type without a buzzing bridge). The buzzing bridge should have a string bridle-type adjustment, unless you are playing a Hungarian instrument, in which case you will use a wedge block system. Have someone who plays well verify that the buzzing bridge is easy to control and has a crisp sound.

Chromatic keyboard. While some “starter” models have diatonic keyboards, these models will limit your music. Even if you have to spend a little more for it, a chromatic keyboard should be a non-negotiable requirement.

Pickups. If you plan to play with amplification, start with build-in pickups. (If you do not plan on ever amplifying your instrument, you can ignore this, but my experience is that you may wish down the road that you had gotten an instrument with this capability.)

Two-octave range. Although some instruments have a larger range, these instruments are usually not suitable for beginners.

Your instrument should also have the following basic features:

String catches or hooks. These allow you to control which strings are sounding and are a required feature.

Easy-to-use tuners. My personal preference is for geared tuners. If your instrument is French-styled and has friction pegs, it should come with a “wrench” of sorts that allows you to turn them when they are under pressure. Hungarian instruments have larger pegs that do not require a wrench. If pegs slip or bind, you can often resolve this with peg dope or chalk, but if you find the tuners difficult to work with in general, it makes the instrument hard to work with.

Buzzing bridge that responds well at different playing speeds. This is hard for new players to assess, so ask for a demo. You should hear a crisp response with fine control at a variety of speeds. If the bridge buzzes uncontrollably at higher speeds, it probably means you will need to replace the bridge. (This is one change that should be easy for a maker and many players to do).

Standard strap knobs or strap locks for the straps. You should be able to change out the strap easily. For French style instruments, you should have two knobs at the head end of the instrument and two at the tail. If you have just one at the head end, you will need a “Y strap” to play standing. If there is just one at the tail end, you will not be able to play while standing.

Can I Build It from a Kit?



Unless you have significant wood-working skills and building your own instrument is a primary goal for you, buy a complete instrument rather than a kit. Building an instrument can be a rewarding activity, but it is not for the faint-hearted and probably won’t save you much money (if any) after you buy the needed tools. If you do want to build an instrument, I would recommend looking at the kits from Hurdy-Gurdy Crafters. Do not buy the Kelischek or MusicMakers kits: These have significant design flaws and by the time you have worked around them to arrive at a mediocre result, you will have spent more than you would have if you had simply bought a good starter instrument.

Evaluating a Hurdy-Gurdy



Regardless of your skill level or the complexity of the instrument you are buying, there are specific things you should look out for in an instrument. Do not get caught up in a feature list that may hide problems with the instrument. I break the items you should look for into several areas.

The following assumes the instrument has been kept at a proper humidity. Because hurdy-gurdies are made of wood, you can expect parts to move and you may find that parts do not fit or move as well if the humidity is too high or too low. When you evaluate an instrument, look for problems that a change in humidity would not address. For example, if you are in a dry environment and they keyboard binds, the problem will only get worse with increased humidity, but if the keys are a bit loose, increasing humidity could help.

Wheel, Axle, and Crank



A proper wheel system is perhaps the most critical aspect of the instrument. Almost anything else can be fixed, but if the wheel is bad, fixing it may essentially require rebuilding the instrument. Look for the following in this system:

The wheel should be made from high-quality laminated materials (like Baltic birch plywood) or composites. In general, avoid solid wood: It moves too much with changes in humidity and is not stable.

The wheel should have a smooth surface, free from irregularities. Rough grain will result in uneven tone.

There should be no wobble, play, or binding in the wheel or crank system. Grab the crank and push and pull it away from and toward the body of the instrument, up and down, and side to side. Any play here is a cause for concern. Turn the crank. If it grabs or scrapes at any point this is a dead giveaway for major problems. If the wheel squeaks, it could indicate that the bearings need lubrication, or it could indicate more serious problem.

The axle should have a proper axle. Stay away from any instruments that use  furniture “T bolts” or similar hardware without a bearing.

The gap between the wheel and the soundboard should be minimal. Large or uneven gaps indicate sloppy construction and allow dirt and debris to enter the instrument and the bearing system.

The axle and wheel should be removable. Although you will not generally remove the wheel, this is essential if the instrument ever needs to be serviced.

The wheel should turn easily with no drag when no strings are engaged. If the wheel takes effort to turn, it indicates problems inside the instrument.

The crank’s handle should spin freely on its own axle. If the crank handle does not turn, it is harder to play. Fortunately, this is usually easy to fix.

The crank should be easy to remove from the instrument. Many players remove the crank when transporting instruments to prevent damage.

Keyboard



No side to side play of the keys. Grab the keys and see if they wiggle side-to-side. If they do, it will result in imprecise intonation. You shouldn’t see up-and-down play either, but this is less important.

Tangents should hit the string close to straight on. When properly set up, tangents should be in tune without having to turn too far to the left or the right. If individual tangents are shifted significantly but their neighbors are not, this indicates a keyboard with the wrong spacing. If the ones at the end closest to the bridge are all shifted in one direction, this indicates a problem with the way the instrument is cottoned, but does not point to a problem with the instrument itself.

The keys should line up. Hold the instrument away from you. The keys should line up evenly. If they are uneven – i.e., some stick out more than others – or you find gaps between them, this indicates a poorly designed keyboard. (Exception: Hungarian keyboards have a different structure with gaps in the upper row. This is fine for that type of instrument.)

Key stems should be durable. Look for keys made from a hard, durable wood that takes a smooth finish. Ebony or rosewood are ideal.

Tangents should be durable. Look for ones made of a hard, durable wood (unless you have metal tangents).

Tangents should be adjustable. Do not consider any instrument where the tangents are not adjustable! They should stay in place under normal playing pressures yet move easily enough to be adjusted by hand

Key stems should be straight. All key stems should be straight with no twisting. If one or two show twisting, it indicates that humidity has warped them. You can have a luthier replace them. But if many or most are twisted, it indicates major problems.

Keys should move smoothly. Keys should smoothly with light finger pressure and return under gravity without shuddering or sticking. Some noise (clicking or slight sliding sound) is normal, but loud scraping indicates problems.

Low action in the keyboard. The keys move no more than 4 mm before touching the string.

Consistent tangent action across strings. If more than one melody string is present, all tangents on a key touch their strings at the same time

No interference from the keybox lid. All keys should move freely when keybox lid is open.

No collisions between adjacent keys. Make sure all keys move independently. If you press one key and another one moves with it, look for obvious causes (like tangents that touch each other).

Smooth keybox lid. The top of the keybox should be smooth and allow easy motion across its surface. Carved keyboxes look nice, but if they impede the motion of your hand, you are better off with something else.

For Hungarian instruments, bracing on both sides of the tangents. Some cheaper instruments have slotted supports only on the side with the keys. Such construction is less stable and tends to have excessive play in the keys.

Wood/body



No cracks or warps. Cracks or warps can indicate major problems. Even if they are cosmetic, why take the risk?

No sunken spots in the back or soundboard. These usually indicate serious structural damage to the instrument.

Quarter-sawn soundboard. You can recognize this because all grain will appear to run parallel, with no obvious grain figuring.

Strings and tuning



Is the instrument set up for the tuning you want? This can be easily changed, but order it for the tuning you want.

Stings should just barely touch the wheel. Without any shimming on the bridge the wheel should just barely contact the string. If you need to add large amounts of cotton to bring the strings into contact with the wheel, this indicates the bridge needs to be cut down. Excessive pressure is easier to deal with: You can add shims beneath the string.

Other



Support piece running from tailpiece to bridge. Hurdy-gurdy bridges must stand up to a lot of pressure. They should be anchored to the tail piece so that this pressure does not pull the bridge toward the wheel. Traditional Hungarian instruments solved this problem by using a heavy bridge that was glued to the soundboard and this construction is also acceptable.

No non-traditional bridge shapes. If it looks strange, ask a luthier to evaluate the bridge. Bridges that are the wrong shape can deaden the instrument’s sound.

Advanced/Step-Up Features



If you are looking to upgrade your instrument, the following features are ones you may consider adding:

More than two melody strings. Third or fourth melody strings add tuning options. Very rarely, instruments will have more than four melody strings.

Additional drones. The standard French configuration has four drones. Adding additional drones allows you to use alternative tunings.

Planetary-gear tuners. These geared tuners look like traditional ebony pegs, but allow more precise tuning.

Active pick-ups and on-board mixer. This setup allows you to balance sound in the instrument itself when you plug it in.

Sympathetic strings. Sympathetic strings provide a richer tone.

Multiple buzzing bridges. These will generally be “stacked” above each other in a small tower and will play at different pitches.

Adjustable bridge. Adjustable bridges use a jack screw system to adjust the height of strings without the need for paper shims. However, not all adjustable bridges are equal and a poorly designed system can deaden the sound. Some move the entire top of the bridge, but if you have more than two melody strings, ones with screws for each string are more versatile.

Capo on the trompette string. This single capo, often made with a harp lever, allows you to raise the pitch of the trompette by a full step to facilitate playing in other keys. For C/G instruments, it will raise the trompette from C to D. For G/D instruments, it will raise the pitch from G to A. This feature does not apply to Hungarian-style instruments.

Capo system for chanter strings. Capo systems change the open string notes on the instrument. Look for capos that operate with a push-button system and that can be adjusted for accurate intonation.

Fingerboard under the drones. This uncommon feature allows you to play notes and harmonies on the drones. Sometime these fingerboards are fitted with movable capos for the ultimate in control over tuning your drones.

String lifters. String lifters are levers or buttons that engage and disengage individual strings without the need for the player to touch the string.

Extended scale. Instruments with an extended scale (sometimes called “alto” instruments) are longer and have a range of around two and a half octaves. They are almost always fitted with capos that allow the instrument to be played as a standard-scale instrument.

Quarter-tone keys (rare). Very rarely you may encounter quarter-tone keys that allow you to play notes in between standard pitches for a few notes. These are most common on the third and sixth degrees of the scale.

Conclusion

Troubleshooting Rosin, Cotton, and String Problems by Arle Lommel


Even for experienced players of the hurdy-gurdy, problems with rosin, cotton, and strings can be a challenge. The following guide tries to demystify some of these problems by listing common symptoms and their solutions.
Before going through the this process, remember that the simplest explanations are usually correct. The vast majority of sound problems can be resolved by fixing rosin and cotton. In addition, if you have tried everything with no luck, consider trying a different cotton or rosin. Sometimes you’ll find that particular batches simply don’t work for your instrument, and changing them can make a big difference.

Weak or Tenuous Sound

  • SYMPTOM: The instrument has a weak or tenuous sound or jumps to overtones rather than the proper pitch. CAUSE: Weak sound generally indicates that you need to add rosin to the wheel. Many players apply insufficient amounts of rosin due to fear of “too much” rosin or to hide other problems in the set-up of their instrument. As you play the instrument, it will gradually lose volume as the rosin on the wheel is consumed and the wheel can no longer create the “slip-stick” friction needed to cause the string to vibrate. SOLUTION: Apply more rosin. IMPORTANT: Solid rosin should have a flat surface with no jagged edges. When you apply it, gently hold the flat surface against the wheel and move it back and forth as you turn the wheel.

  • SYMPTOM: One or more strings have a weak sound that does not improve when you add rosin. CAUSE: The string’s pressure on the wheel is insufficient and the wheel cannot make the string vibrate effectively. This indicates that the string is either sitting too high at the bridge or that it does not have enough cotton. Because bridges move with changes in temperature or humidity, previously ideal set-ups may no longer work and need adjustment. SOLUTION: Examine the relationship of the string to the wheel. If you have a reasonable amount of cotton on the string and you can see that the string is not making solid contact with the wheel, you may need to remove shims or lower an adjustable bridge. If you cannot lower the string at the bridge, you may need to add additional cotton.

Harsh Sound

  • SYMPTOM: One or more melody string has a harsh sound, particularly on high notes. CAUSE: The string is pressing too heavily on the wheel. This effect is most obvious on higher notes. There are two primary reasons for this condition: (1) The string has too much cotton; (2) The string is sitting too low at the bridge. SOLUTION: With experience, you can generally see whether the problem is cotton or the bridge and address it directly. For newer players, it may be easier to address both issues at the same time. To do this:
  1. Remove the cotton from the string.
  2. Check the pressure of the wheel on the bridge. The ideal pressure of the string without cotton should be such that the wheel barely deflects the angle of the melody strings. If you can see a noticeable bend, you need to raise the string at the bridge by adding shims or using the jack screw if you have a adjustable bridge.
  3. Apply cotton and check the sound. You will probably need to add rosin after reapplying the cotton. The amount of cotton you use depends on the instrument and string type you use. Higher-pitched strings generally require less cotton than lower-pitched ones.

  • SYMPTOM: All of the strings have a harsh or scratchy sound. As you turn the crank you may hear that it is worse at some positions than others. CAUSE: Poorly applied rosin. This is the classic case of “too much rosin,” but is actually not caused by the amount of rosin. If rosin is applied with too much pressure or by using a broken or jagged block, it leaves ridges of broken and jagged rosin on the wheel. This prevents the free movement of the strings on the wheel. SOLUTION: In the vast majority of cases, you can resolve this problem by disengaging all strings and then pressing a clean, lint-free cloth against the wheel as you turn it. Use a fair amount of pressure: Your goal is to smooth the rosin out and the friction and heat between the cloth and wheel help to achieve this goal. You will generally need to recotton the strings at the same time because the cotton picks up the bits of rosin and can redeposit them on the wheel and create the problem over again. If you are not lucky, you will find that the scratching sound persists even after you use a cloth on the wheel. If you have repeatedly tried to use a cloth and the problem persists you may need to be more aggressive. Usually you will notice that the scratching corresponds to one or more particular spots on the wheel. This indicates uneven build-up of rosin. In such cases you can either use a sheet of 600-grit or finer sandpaper on the wheel while turning it to remove the buildup or use a razor blade to gently scrape the rosin on the wheel. You scrape it by holding the blade in the direction the wheel is turning and letting the edge pick up any high points. You are not cutting the wheel and should never have the blade face into the wheel where it could cut or gouge it. [NEED A DRAWING OR PICTURE HERE.] This build-up is most likely to occur on the edges of the wheel, so focus on those areas. Be very careful: You do not want to scrape the wheel’s surface. You want to remove only the uneven rosin. I have only had to take this approach twice in twelve years with my primary instrument. In very rare cases, you may have serious problems with rosin that require stripping the rosin from the wheel with alcohol on a rag. This is a last-resort solution and you should take this approach only after you have tried everything else. Note that if you strip a wheel you will need to apply rosin more frequently until the wheel builds up an even coating.

Dead Spots on the Wheel

  • SYMPTOM: The wheel has a dead spot that does not make sound. CAUSE: Part of the wheel has insufficient rosin or you have grease or other contamination on the wheel. SOLUTION: There are four solutions you can try, in the following order based on how involved they are:
  1. Reapply rosin to make sure that you do not simply have an area with insufficient rosin. Often reapplying rosin will address small skips or stutters on the wheel.
  2. If reapplying rosin does not address the problem, use a clean, lint-free cloth and press it firmly against the wheel while turning it so that the cloth absorbs the contamination. Reapply rosin and check the sound. This approach will address most minor contamination, such as from people touching the wheel.
  3. Strip the wheel with rubbing alcohol on a cloth. Alcohol will remove most greases from the wheel. Note that if you strip a wheel you will need to use apply rosin more frequently until the wheel builds up an even coating.
  4. For cases of severe contamination, you may need to use sandpaper or a razor blade to scrape the surface of the wheel as described above. Be very careful with this approach, as you want to remove as little material as possible while still getting rid of the contamination.

Tangents Do Not Line up Properly

  • SYMPTOM: You have to point the tangents for high notes on one or more melody strings toward the bridge. You find that the amount of deflection increases as you get closer to the bridge. CAUSE: You have too much cotton on the string. Too much cotton adds mass to the string and requires that it have a shorter vibrating length than it should to reach a given pitch. This effect is more pronounced for higher notes because the cotton constitutes a higher proportion of the mass of the vibrating portion of the string for higher notes. SOLUTION: Remove the cotton and reapply a smaller amount. Retune the strings and adjust the affected tangents.

  • SYMPTOM: You have to point the tangents for high notes on one or more melody strings away from the bridge. You find that the amount of deflection increases as the tangents get closer to to the bridge. CAUSE: You have too little cotton on the string. They tangents are positioned to adjust for a certain amount of cotton on the string. If there is not enough, the vibrating length of the strings has too little mass and is sharper than expected, so you have to angle the tangents away from the bridge. Note that this condition is relatively uncommon because most instruments are set up with a small amount of cotton in mind. SOLUTION: Remove the cotton and reapply a greater amount to the string(s). Retune the strings and adjust the affected tangents.

  • SYMPTOM: All of the tangents systematically face toward or away from the bridge, without affecting the higher notes more than the lower ones. CAUSE: The distance between the bridge and nut is incorrect or the keyboard is poorly designed. SOLUTION: If the keyboard has a design problem, there is little you can do. However, most instruments have an adjustable nut that allows you to change the vibrating length of the open string. If the tangents all point toward the bridge, adjust the nut to increase the length of the string. If the tangents all point away from the bridge, adjust the nut to decrease the length of the string. Tune the string and check the position of the third and tenth keys in the lower row (the two Cs on a G/C instrument or the two Gs on a D/G or the two As on a Hungarian instrument). Adjust the position of the nut to find the smallest deviation for the tangents on these two keys. After finding this position, tune the string and adjust the tangents for all of the keys.

Problems with Individual Tangents

  • SYMPTOM: Individual notes warble or have an unstable pitch. CAUSE: Individual tangents have worn spots or notches. These cause the tangent to have uneven contact with the string, which vibrates or moves against the tangent. SOLUTION: Put tape or heat shrink on the tangent, or sand the face of the tangent (if wooden). Your goal is to create an even surface on the tangent to press against the string. Note: Before you attempt to solve problems with individual tangents, make certain that your cotton, rosin, and shimming or bridge adjustment are all correct. Sometimes problems in these areas are apparent only on a few notes, usually those closer to the bridge. If you have corrected any problems in this area and you still find issues with unstable pitch on particular notes, focus on the tangents.

  • SYMPTOMS: When you press in a key you hear different pitches on different melody strings. CAUSE: The tangents do not touch the melody strings at the same time or one tangent is twisted. They touch one string but not the other. SOLUTION: Check the tangents to find out why one is not making contact with its string. Adjust as needed to ensure that they touch the strings at the same time. If you have recently changed the gauge of one string, you may find that you need more involved work to get the tangents to work properly. Such work is beyond the scope of this guide.

Pitches Wobble

  • SYMPTOM: The pitch of the instrument wobbles rhythmically in time with the wheel. CAUSE: The wheel is out of true. It is not perfectly symmetrical about the axis of rotation. As a result it applies more uneven pressure on the string as it turns, leading to fluctuations in pressure. SOLUTION: Truing a wheel usually service by the maker. Most modern instruments with laminated or composite wheels should never have this problem unless they have been exposed directly to significant moisture. If you find this problem, it may indicate other damage as well, and you should have the instrument evaluated by the maker or a luthier experienced with hurdy-gurdies. Truing a wheel is not difficult, but if it is not done properly, attempts to true the wheel can make problems worse.
