Basics – loosen hairs after playing, do not use the tip of bow to tap on objects, change the hair of bow once a year.
When not using the bow, hair must be loosen until they touch the rod; otherwise the spring of the rod will weaken and become a bow with upper arc. It is important to remove tension and protects the wood from warping. If this not done, the rod will start to rise, making it impossible to be properly tightened bow, and the glove compartment that holds the hair can be broken, trying to tightened more. If the bow was left stretched long enough stick looks like it has lost its natural arch, loosen the drive and leave it for a day or two, if it does not restore the arch having to visit a qualified luthier to recovery it.
In applying rosin (rosin round is best), do rotate in the application that prevent to not wear unevenly, if applied in the same position for a long time. Approximately 10 times up and down enough. If the bow is new or after replacement of the hair should be rubbed well rosin before use. If much white powder can be seen in Instrument after playing, you have probably used too much rosin. If you notice dust rosin on of bow stick, wipe it with a soft cloth.
Avoid touching bow hair with your fingers. Oil from your hands can create a slippery spot on them and prevent the retention of rosin in these places, and thus destroy the stability of contact of hair with string and produce a good sound.
Be careful not to touch the tip of bow against something hard (even slightly). This is a very delicate part, and nose can break off easily and is difficult to repair.
The quality of bow is important for making a quality sound from your instrument. Bows must be kept clean and the hair should be changed regularly / annually /. Indicator about the need for change of hair: missing hair, the hair becomes very dark and oily, not mesh well string, need more rosin to a good contact, begin to break often, or when they cannot be stretched enough. When tear hair use scissors to cut the rest. Pulling hair can loosen the knots that hold the hair on top and in the glove compartment.
After changing the hair may feel that, the bow has lost some of the sound quality (more noise, gritty sound, rough feeling). He just needs a couple of weeks playing. At the beginning, hairs do not retain equally rosin, and while this does not happen bow may have sandy sound.
It is important that the tightening and loosening be easy, if not so take it for repair, before further damage occurred. If not paying attention to the bow in this condition may lead to damage to the internal production, especially hole, and can lead to cracks in the rod of bow.
If all the hairs jump out from the nose suddenly, do not panic, the bow is not destroyed, just the wedge clamping hair is gone, and can be repaired easily by luthier.
Other things that occasionally need to be replaced are the handle and winding. Winding counterweight to the gravity of bow and is made of silver-plated copper, silver, rare steel and even more rarely plastic .. It has aesthetic and functional value for a bow, but sometimes develops. The handle is made of leather and allows comfortable positioning of the hand to avoid sliding of fingers and prevent the rod from the clutches of thumb moisture. The skin also slows the wear of winding.
