<p>PROBLEM TO BE SOLVED: To make it possible to obtain the sounds ample over the entire part from the high pitch to the low pitch with good vibration of a tubular body, to improve the performance as a musical instrument, allows the easy impartation of changes in timbre and to provide broad playing expressions by providing either one surface of a finger hook and a pedestal with plural pieces of studs and forming a spacing between the finger hook and the pedestal. SOLUTION: The finger hook 7 is prevented from rotating by the pedestal 13 mounted at the outer peripheral surface of the tubular body 2 and is fixed by a set screw 14. A projection 16 is detained into a recessed part 12, by which the rotation of the finger hook 7 is prevented. Further, the spacing is formed by the studs 11 between the finger hook 7 and the pedestal 13 in the state of fixing the finger hook 7 and the pedestal 13, by which the surface-to-surface contact of the flat plate part 7B of the finger hook 7 with the pedestal 13 is averted. If the spacing is formed between the finger hook 7 and the pedestal 13, the resistance of the finger hook and the thumb hooked to the finger hook on the tubular body 2 to vibration is made lower than in the case of the conventional material structure of making the surface-to-surface contact.</p> |
