SOLUTION: Sound holes 7 of intervals B(flat) , B, C, C#, D, and E(flat) in a bass band placed in bell joints and long joints out of sound holes formed in a tube main body 6 are formed at an angle to an axial line 21 of the tube main body 6 so that an inside aperture end 20a is on the high pitched side and an outside aperture end 20b is on the low-pitched side. It is desirable that this angleδof inclination of sound holes 7 is 10 deg.<=δ<=20 deg..</p> |
