ABSTRACT:
Tone holes are formed in a bell joint and a long joint for producing lower register tones Bb, B, C, C#, D and Eb and obliquely extend with respect to a center axis of an air passage formed in the joints in such a manner as to have inner ends closer to a tone hole assigned to a higher register tone than the outer ends thereof, and the oblique tone holes suppress undesirable sharpness in intonation and allow a player to smoothly produce the sounds.
