The CodaBow Joule Viola Bow: Energy and Control

Review of CodaBow Joule Viola Bow

The CodaBow Joule Viola bow is an amazing bow for the price. The suggested list price is $735.00. The bow has a sleek carbon fiber design with a Kevlar acoustic core and a graphite diamond weave. The frog is the “turbo” design manufactured specifically for CodaBow by the Walter Paulus Gmbh of Germany. It is made of Xebony, which is engineered ebony. The frog is nickel mounted with a sterling silver coda sign inlaid on each side. This bow is very attractive visually. The bow also boasts a 10 year warranty.

The Joule gets its name from the Joule unit for measuring energy. The bow adheres well to the string in when playing detaché strokes. It pulls an even sound from frog to tip and back from tip to frog. The Joule is easily controlled in martelé strokes and has a fast and even spiccato. The ricochet and sautillé strokes are easy to control.

The Joule is marketed as a bow designed for extended range instruments but plays great on a standard four string instrument. This bow weighs 70.2 grams and the balance point is 9 3/4 inches. The bow is very stable on the string in legato passages and is extremely responsive. The Joule with the turbo frog makes long slow bows feel like they can be sustained for a longer period of time than a bow with a traditional frog. The sound produced by a carbon fiber bow tends to have more clarity than a wood bow although some warmth of sound is lost. Because this bow is so responsive hair tension and hair length greatly effect the way the bow plays. Upon finding the appropriate hair tension the bow reacts to every nuance. This bow rivals a fine pernambuco bow. It is an excellent choice for viola because it allows good grip on the C string and a fluid and silky sound on the A string. This bow drives like a finely tuned Lamborghini but is priced like a Toyota. The Joule viola bow makes a wonderful bow for an advancing student or an excellent addition to a professional violist's arsenal of bows.

Q and A: Why does my bow bounce?

Question: Hi, I've played violin for about 15 years. When doing long bow strokes, especially on open E, I get a little bounce in the middle of the stroke/bow. Normally don't notice it in the middle of a passage, especially with vibrato "hiding" it. I try to keep my arm and wrist totally relaxed, but I still get a little bounce that breaks up a smooth phrase. Any advice? Thanks

Answer: This could be caused by your bow.  Every bow does this to some extent, the problem is when you can actually hear it.  When a bow is tightened too much it can become bouncy and hard to control.  Check the stick of the bow to see if it is warping in one direction or another.  If it is warped, have the stick straightened by a qualified luthier.  A good luthier can also adjust the camber on your bow to minimize the bounciness.  If you find that nothing works to control this problem it might be time to look for a different bow.

How to Care for Your Violin Bow

It is important to develop good habits when caring for your violin bow. A good and responsive bow makes a huge difference in the sound of your instrument. There are several key points to remember to properly maintain your bow. Most importantly, always loosen the hair when you are finished playing. This is done by turning the bow screw counter-clockwise. You should feel the stick relax back into it's original arch (camber). If the bow is left tightened for extended periods, the stick can lose its camber and can even warp. Furthermore, the hair can stretch out. If the hair stretches too much, you will not be able to tighten the bow to playing tension. It is vital to remember never to force a bow to tighten because it is possible to break the butt end of the stick by forcing it. If you can't tighten the hair, you should take it to your violin shop for a possible rehair. Bows should be rehaired depending upon use and the condition of the hair. There isn't one rule about how frequently to have a bow rehaired.
An additional key to caring for your bow is to remember never to touch the horsehair with your fingers, as dirt and oils can get on the hair that will cause it to lose its ability to accept rosin. In general, it is always a good idea to wash your hands before you play your instrument. Some peoples' hands tend to perspire profusely. Not only can the sweat remove the varnish from the stick, iit can also soil the hair at the frog. For those with sweaty hands, frequent hand washing is more than a recommendation -- it is a must. When perspiration builds up around the frog of the bow, it can attract grime that can cause the frog to get stuck in position on the stick. When this happens, the frog will not move -- even when the bow screw is turned to loosen the hair. If this happens, the frog should be taken off of the stick, using care not to allow the hair to become twisted. Then, the stick should be cleaned. If you find that your hand is "eating away" at the stick or the varnish, you can have your luthier apply a long leather to the handle of the stick to protect it. This is frequently done on fine bows to preserve the makers' stamp from wear and tear.
The frog glides back and forth on the stick by a simple mechanism of a bow screw and an eyelet. The bow screw is usually made of steel and the eyelet is usually made of brass. The brass eyelet is a much softer metal than the bow screw and can strip. If you find that you cannot tighten or loosen your bow, chances are good that they eyelet has become stripped. On occasion, it is possible to carefully remove the frog from the stick and turn the eyelet one-half of a turn, in order to locate some remaining thread left that has not yet become stripped. Then, it is possible to reset the frog back on the stick and reset the bow screw. This doesn't always work, but it is worth a try.
On the stick near the frog is the thumb leather and winding. The thumb leather is there to protect the stick from the thumb and thumb nail. Over time, your thumb nail can wear through the leather and start carving into the stick. If your thumb leather is warn, you should have it replaced at your next rehair. This will help preserve the stick and value of your bow.
The head of the bow is very fragile and under a lot of tension. At the head, you will find a tip plate. The tip plate can be made of metal, plastic, ivory or mammoth and is there to protect the head of the bow. If your tip plate is not made of metal, it can break when bumped or can crack if the hair isn't carefully inserted during a rehair. If it should crack or break, you should have it replaced immediately.
Using too much rosin is a common mistake made by many players. Rosin should be applied sparingly and only when needed. You should not see a white cloud of rosin come off the bow when you play. Once there is too much rosin in the hair, it is nearly impossible to get out. When you use too much rosin, it will build up on the strings and your sound can become very scratchy -- since you are essentially playing with rosin on rosin. Also, rosin can build up on your instrument and damage the varnish over time. To avoid this, it is important to wipe off your instrument, strings and bow shaft with a clean soft cloth each time you finish playing. Microfiber cloths work great for this.
Tightening the bow too much when you play is another common mistake. There is no rule for how tight a bow should be as it depends on the strength and camber of the stick and is different for every bow. If your bow is too tight, you will have trouble controlling your bow and it can become too bouncy when an even sound is desired. You can test how tight to make your bow by playing long and even strokes. The hair should just barely clear the stick at the middle of the bow. If you see a big gap between the hair and the stick, then your bow is too tight. You can keep experimenting with hair tension until you find that you have good control over the bow.
When you have develop good habits you will find it very easy to maintain your bow. Eventually, you should be able to do this without even thinking about it.

How to Choose a Bow to Use It In a Fiddle Contest

When considering the best bow for fiddling, iit may seem that every fiddle player has a different opinion. Choosing a bow is a very personal decision. Fiddle music is very demanding and a having a responsive bow is a must. I have observed that fiddle players use everything from the most inexpensive bows to fine old French bows valued at over $20,000.

One option that is becoming very popular is carbon fiber bows. The advantages to carbon fiber bows are that they are very stable, difficult to break and do not warp. A favorite carbon fiber bow is the CodaBow brand. CodaBow makes several models which are designed to accommodate many different levels of players.

When playing demanding fiddle tunes, a bow with a strong stick may seem to perform best for many players. Keep in mind that the stronger the stick, the less hair tension is needed. Each bow will dictate, depending upon strength of the stick and its camber (the arch in the bow), how tight it needs to be. A common mistake is to tighten the bow so much that it becomes bouncy and hard to control. There is no rule about how tight a bow should be. Again, it depends upon the individual bow and the player's preferences.

A common mistake is to put too much rosin on the bow. Many players and teachers feel that they should rosin the bow every time they play. This is not the case. Rosin should be used to help the bow grip the string. If you find a white cloud of it coming off the bow hair when you play, then you are using too much. With rosin, generally less is more. If you feel the hair slipping on the string then apply more of it sparingly until you feel the bow grip the string.

It is important to remember to loosen the bow when you are done playing. When tension is left on the hair, it will stretch. Once the hair is too stretched out your bow will no longer tighten. If you can't tighten the bow, don't force it. Take it in to you local luthier for a rehair. Many bows have been damaged by trying to force them to tighten. The other reason for loosening the hair is to let the stick relax back into it's natural cambered shape. If a bow is left tight for too long it will lose its camber and can warp.

Do you know if CodaBow has released a replacement for the Aspire yet?

Coda has replace the Aspire bow with the Prodigy. It is available in 3/4 and 4/4 size. It plays differently from the Aspire. It handles like a more advanced bow. It is made with the new Diamond technology. Also, the stick has a smaller feel in the hand than the Aspire did.

Which Coda Violin Bow is Right for my Student?

This is a difficult question to answer. I have noticed that beginning students seem to do well with basic brazilwood bows as they can be a little heavier than average and are usually balanced more towards the tip. Those bows make it very easy to put the bow in the string and pull a big and even sound. Most brazilwood bows are very stable on the string. Once the student starts learning more difficult repertoire the bow can become difficult to handle. Spicatto, Staccato and Ricochet bowing techniques are some of the examples of when to move to a finer bow.

The only way to really be certain about which bow is the best choice is to have the student try out several. Everyone uses different bow pressure (arm weight) and bow speed and it's important to pick the bow that functions well for the student (not the teacher).

The Coda GX bow is an outstanding value for the money. In our shop it competes very well with wood bows that are priced four times as high. The Coda GX bow has become our best selling bow. The Coda Joule bow is also a great bow for advanced players, especially those who play fiddle music or extended range instruments. It gets an amazing clarity across all of the strings and is extremely easy to handle. The Coda Prodigy and NX bows are great step-up bows for the advancing student.

I have a bow made of wood of pernambuco. I know it is worth several thousand dollars. Today, I accidentally dropped it on the floor and it broke. I

Take the bow to your luthier and see if it can be repaired. If it can then get an estimate and talk to your insurance company. Depending on where it's broken, if it can be repaired, it should play like it did before but it will loose significant value.
