Abstract
A valve assembly including at least one valve body designed to be mounted on a musical instrument, such as but not limited to a trombone or like “brass” instrument and adapted to regulate air flow through the instrument, between at least a first path of air flow and a second path of air flow each having significantly different lengths, wherein a musician is capable of selectively directing air from the mouth piece or air inlet of the instrument to the air outlet or bell of the instrument along an extended length flow path of the instrument, thereby extending the lower range of the instrument and generating a change in pitch and tonal quality of the musical sound generated. The valve assembly can also include a plurality of valve bodies, each having an elongated, preferably straight line configuration with an open outlet end and an open inlet end as well as an outlet port communicating directly with the inlet end through a first bore and an inlet port communicating directly with the outlet end through a second bore. The shape of the inlet and outlet ports as well as the orientation and configuration of the first and second bores are such as to define a smooth, substantially unrestricted flow of air through the instrument regardless of the selected flow path through which the air is directed.
