A musical wind instrument, comprising a mouthpiece, key mechanism, body, and an alternative material bridge that is couple a first and second opposite facing tube. There is in an alternative embodiment at least one coupling mechanism affixed to at least one of the opposite facing tubes designed to releasably hold the wood based material bridge against the first and second tubes. Alternatively there is a musical wind instrument made of a predominantly first material, comprising a mouthpiece, key mechanism, and body; at least a first and second tube having a portion thereof being spatially opposite to each other respectively, and a bridge, having a first and second end that are coupled to the first and second tube respectively, wherein the bridge is made of an alternative material that is different from the predominantly first material of the instrument.

A fluid flow control valve comprising an outer casing with an inner valve member displaceable between first and second positions within the casing, the valve member including passages which interconnect different valve inlets and outlets dependent on whether the valve member is in its first or second position, the valve member being made from plastic material so that the diameter of the valve member can be increased without increasing its weight above that of a conventional metal inner valve member. This allows the passages through the inner valve member to be of the same internal diameter as the tubing leading up to and away from the valve. The valve member can be acted upon by a magnetic restoring means which tends to return the valve member towards its first position when displaced therefrom.

The present invention provides a wind instrument trumpet and its manufacturing and molding methods. The wind instrument trumpet of the present invention adopts polymeric material with integrated molding process, reducing trumpet spare part quantities and optimizing spare part structure. Moreover, the wind instrument trumpet of the present invention has a lighter overall structure and purer tone quality by applying integrated molding process to the piston outer pipe of tuning component. The present invention greatly decreases the quantity of spare parts, improves assembly accuracy and efficiency, reasonably controls the accuracy of a single spare part while improving the matching accuracy considerably, ensures the movement direction of keys more effectively through the coordination with the piston outer tubes so that the keys are smoother compared to the traditional ones.

A brass instrument includes a mouthpiece configured to convert vibrations of player's lips into sound and take the sound inside; a bell configured to magnify a volume of the sound taken by the mouthpiece and release the sound to the outside; and a main tube intervening between the mouthpiece and the bell, and is characterized in that the main tube includes a main tube body formed to spread out in a spiral manner in a state in which side surfaces of the main tube body are closely attached to each other, and a part of the closely attached side surfaces of one of the tubes constitutes a part of the side surface of the closely attached other tube.

A Euphonium Extension Rest for a portable device to support a musical instrument such as a baritone horn, a euphonium, a small tuba, or a similar instrument with a portable stand so that a musician can handle the instrument for lengthy sessions; the device includes an extendable wrap with a left-hand and right-hand curved side rail and a bottom half of a hemisphere, a protection cushion contiguous to the curved side rails, a way to secure the protection cushion to each of the left-hand and right-hand curved side rails, and a securing manner to releasably encircle the musical instrument to hold the extendable wrap.

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.

Apparatus attached to the flared open end of a wind instrument includes one or more layers of particle filtering materials for preventing the dispersion of pathogens from the wind instrument while enabling sound transmission with little muffling and distortion, and minimal resistance for the musician.
