The Xaphoon's sound falls somewhere between a saxophone and a clarinet ' a much richer sound than its size would suggest and was born to be played wherever and whenever the mood strikes. The experienced player will find the Xaphoon capable of all the subtle shadings and vibrant power of a saxophone. The beginner will find it fun and easy, and good practice for other reed instruments. The Pocket Sax is in the key of C and uses a standard tenor sax reed.
