A woodwind instrument ligature comprises a plurality of ligature bodies; each body having first and second ends; an aperture extending through each end; the apertures at each first end being coaxial and the apertures at each second end being coaxial; a first tensioning member located in the apertures of the first ends and a second tensioning member located in the apertures of the second ends; each tensioning member having a transversely extending bore, a fixing member extending through the bores of the tensioning members, the fixing member being adjustable to urge the tensioning members together or apart; wherein the ligature body comprises a flexible material having a length to wrap around a mouthpiece and reed for a musical instrument to form a channel to receive the mouthpiece and reed, with the tensioning members being connected by the fixing member in use; each end having first and second contact surfaces; wherein each end may be rotated about the tensioning member between first and second positions; wherein in the first position, the first contact surface faces inwardly toward the channel and the second contact surface faces outwardly in use and wherein in the second position, the second contact surface faces inwardly and the first contact surface faces outwardly from the channel in use.

In one aspect, the present disclosure provides a method including rotating a rotatable surface with an object positioned thereon to a plurality of angular positions. The method also includes capturing, via an x-ray microtomography device at each of the plurality of angular positions, a tomograph of the object. The method also includes summing each tomograph of the object to create a three-dimensional image of the object. The method also includes using an additive manufacturing machine to create a three-dimensional replica of the object using the three-dimensional image of the object.

Aerophone toy building blocks to make a plurality of combination of sounds comprising of a plurality of building blocks, each the block having four walls, a top lid and a bottom cap to make a body having an inner space; at least two of the walls, the lid and the cap having releasable couplers; each the block having aerophone musical instruments to produce sounds; each the block having a plurality of airway channels inside the inner space, the airway channels are connected to the adjacent airway channels; the blocks having the same or different sizes, whereby larger blocks create lower pitched sounds, while smaller blocks create higher pitched sounds; the blocks having the same or different materials to let the instrument produce different sounds; the musical instrument being mounted either onto or inside of the body of the building block, or being permanently encased within the material of a block; and an air source to be attached to the plurality of building blocks to provide an air flow to each aerophone instrument.

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.

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.
