Bassoon reeds are very delicate and require careful maintenance. They must be soaked in water before playing, and they need to be replaced regularly. The life of a bassoon reed can vary depending on the quality of the reed and how it is cared for, but most reeds will last for several weeks.
Making bassoon reeds is a specialized skill, and there are many different schools of thought on how to make the perfect reed. Some bassoonists make their own reeds, while others prefer to buy reeds from professional reed makers. There are also a number of different commercial reed makers who make reeds for bassoons.
The best way to find a reed that works for you is to experiment with different reeds until you find one that gives you the sound and intonation that you are looking for.
