Disclosed is a bass clarinet that enables even splitting of the harmonics without compromising the efficacy of the instrument, without increasing manufacturing costs, and without the requirement of a clarinettist relearning how to play the instrument. It is further an object of the disclosure to describe bass clarinets with the ability to change harmonics without requiring the player to compensate with embouchure and air pressure.

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.

An apparatus having two levers working in tandem with each other such that when pressing one lever, triggers the other lever which closes the hole that needs to be closed. The length and the contact point of the lever may be variable. The diameter of the large and small straps is also variable. A combination of these variables allow this invention to close any hole on any woodwind device, regardless of its location or size. Moreover, the free finger or any lever working in conjunction with this lever, may be anywhere on the woodwind instrument which may overcome the variability in the length of fingers of different artists.

A disk of a wind instrument includes an integral body made of a material which is in a solid state at a room temperature and in a malleable state at a predetermined temperature higher than the room temperature. The disk is configured to stabilise a pad assembly in a key cup for closure of a tone hole of the wind instrument.

A wind instrument includes a tubular body, a key, and an adjuster. The tubular body includes a tone hole. The key is mounted to the tube body, and includes a pad and an operation part. The pad is configured to cover the tone hole. The operation part is configured to move the pad away from the tone hole. The adjuster is configured to adjust a maximum distance the pad moves away from the tone hole by the operation part.

Air pressure regulation devices and methods of using air pressure regulation devices are provided to adjustably control air flow to a bagpipe chanter reed. An air pressure regulation device can include a main body, a valve rotatably attached to the main body, and a cap attached to the main body. The valve may be rotatably adjustable to control an amount of air that flows through the air pressure regulation device. Methods of using an air pressure regulation device may include installing an air pressure regulation device on a bagpipe, adjusting the air pressure regulation device, and playing the bagpipe.

A pad assembly for a flute or other woodwind instrument is provided. The pad assembly may have an upwardly protruding chimney on either a pad base or integral to the pad itself. The pad assembly may be held in place by a washer and screw that is screwed into a spud of a cup, which moves to open and close a tone hole. The upwardly protruding chimney causes compression between the pad and washer, and prevents the washer from directly contacting the spud by creating a spacing between washer and spud. Such a configuration allows the pad assembly to remain in a correct orientation if the cup and a tone hole are misaligned.
