Described is a twin valve attachment for musical instruments, such as a trombone. The attachment includes a lever that is rotatable between a B-Flat configuration and an F note configuration. Also included are first and second rotary valves. The first rotary valve is operably connected with the F lever, while the second rotary valve is operably connected with the first rotary valve. F-attachment piping is fluidly connected with both the first and second rotary valves. Thus, a user may rotate the F lever to selectively direct air flow through the F-attachment piping (for the F note configuration) or bypass the F-attachment piping (for the B-Flat configuration).

A valve casing includes a body that defines a plurality of channels for receiving a plurality of valves and a plurality of ports. The plurality of ports include one or more inner ports, which place two adjacently positioned channels in fluid communication with each other, and a plurality of outer ports for directing a flow of air out of the valve casing or receiving the flow of air into the valve casing. One or more areas between adjacently positioned channels can be partially or completely filled with a mass to attenuate the vibration incurred by the valve casing as the flow of air is directed therethrough. One or more of the outer ports can be defined by a curved protuberance to provide a more ergonomic and comfortable playing arrangement during use of a musical instrument in which the valve casing is implemented.

B/F tenor trombone for children, comprising a sound part and a slide, composed of an inner slide and an outer slide being movably disposed thereon, wherein the total length formed by sound part and slide has a tubing length L.sub.s1+L.sub.s2+L.sub.s3+L.sub.z1+L.sub.z2+L.sub.z3, and wherein in the 1st register, the slide has a tubing length L.sub.z1+L.sub.z2+L.sub.z3 of less than 150 cm, and wherein the sound part has a tubing length L.sub.s1+L.sub.s2+L.sub.s3 of more than 125 cm.

Systems for raising pads on musical instruments to enable drying of pads and increase air flow around the pad and a body of the musical instrument. A vent spanner device, including a positioning feature and a retention feature, is placed between a pad and its corresponding vent to create an air gap. A pad prop is placed against a key mechanism or between the key mechanism and/or the body to raise a pad from sealing its corresponding vent. A linkage feature connects one or more vent spanners, pad props, end pieces, key mechanisms, or the body, and provides storage.

A key guard height adjuster for a brass instrument having a threaded rod configured to be received by a threaded bore of a key guard; a stem connecting the threaded rod to a key guard height adjuster head; and the adjuster head having a rounded top and a knurled edge. According to one approach, the adjuster head height can be in the range of about 4 mm to 10 mm. According to one approach, the adjuster head diameter is in the range of about 8 mm to 12 mm. According to one approach, the adjuster head is about 8 mm in width and about 6 mm in height.
