Shakuhachi Care and Cracks
Shakuhachi care – Why does bamboo crack?
Bamboo shakuhachi care is actually quite easy compared with many other musical instruments. Cracking or splitting is the main concern. However, cracking is in bamboo’s very nature. Conveniently, it makes it easy to split by hand for the crafting of countless items. It’s certainly one of bamboo’s most useful traits. However, when the air becomes too dry for a particular pole of bamboo, such as a bamboo shakuhachi, it can crack/split along its length (y-axis). If this happens, bindings are applied to close and repair the crack(s). Bindings can also be applied to greatly help prevent cracks in the first place (to see how bindings are applied click here).
How to prevent cracks in lieu of bindings
When it comes to shakuhachi care, bindings are the single best solution for crack prevention. Once bound, there is very little chance that a shakuhachi will crack. In the rare chance that a bound shakuhachi cracks the bindings almost always keep the cracks in check requiring no repairs. However, if your shakuhachi is not bound then it’s best to avoid extremes in temperature and humidity whenever possible.
To reduce the risk of cracks, use humidified storage when the humidity drops below 50%. Pictured below is one of the easiest methods for humidified storage.
In the image, a damp piece of material is placed between two ‘twists’ at the top of a plastic storage bag. It’s then held in place with a rubber band. Be sure to check for mold on the damp material and replace as necessary or clean with distilled white vinegar. You can use a bit of sponge, paper towel, or fabric.
How to prevent odors and mold
After playing, swab the bore with a tsuyutoshi which is a bit of fabric with a pull-string tied to one corner. To make one, cut fabric to a size that will fit down the bore (try 1 sq. ft. or 30 cm sq.) and tie a string longer than your shakuhachi to one corner of the cloth. When pulling through, protect the sharp blowing edge with the soft part of the thumb. A 50/50 mix of distilled white vinegar and water can be used to clean the inside as well. In summation, I hope you can see that shakuhachi care really is quite simple. Enjoy, Josen
