A slide trombone is provided which has an activatable attachment which lengthens the basic windpath 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 &musicf& /G &musicn& , the slide has a shorter reach than is conventional for a B &musicf& /F or other known B &musicf& /G &musicn& , trombones. Therefore, for the B &musicf& /G &musicn& , trombone, the slide may lower the pitch by five complete semitones. The trombone can also be tuned to C/A, D &musicf& /B &musicf& , E &musicf& /C, and F/D. In the D &musicf& /B &musicf& embodiment, the trigger action may be reversed.
