TROMBONE

Title:SINGLE TRIGGER MINOR THIRD ATTACHMENT SHORT REACH SLIDE TROMBONE

Inventor(s):B. P. Leonard

Disclosure 160 U.S. Patent 5,435,222

A slide trombone is provided which has an activatable attachment which lengthens the basic wind path of the instrument.The attachment is activated to lower the basic pitch of the instrument by a minor third.The instrument further has a reach (i.e. the distance which the slide travels from its innermost position to its outermost position) which does not exceed 55 centimeters. Thus, when the trombone is tuned to B /G , the slide has a shorter reach than is conventional for a B /F or other known B /G trombones.Therefore, for the B /G , trombone, the slide may lower the pitch by five complete semitones.The trombone can also be tuned to C/A, D /B , E /C, and F/D.In the D /B embodiment, the trigger action may be reversed.

A slide trombone is provided which has an attachment that is activated by a single thumb trigger to lower the basic pitch of the trombone by a perfect fifth.This attachment configuration permits the player to play all the chromatic tones between the tenor range and the pedal notes using a standard length slide.
