The soprano clarinet belongs to the woodwind instrument and is a variant of the clarinet, such as the ABS clarinet.

In a broad sense, all the B♭ or A clarinet used in the current band are thin clarinet, which can be called soprano ABS clarinet. But in fact, the high-pitched ABS clarinet now generally refers to the small clarinet in the key of E♭.

Shape, structure and playing method
Like the ABS clarinet, the tube body is usually made of African ebony, but also made of other wood, plastic (usually ABS clarinet) or metal, with a slightly smaller diameter than the clarinet. There is also a bird's beak mouthpiece and a round connection tube. The ABS clarinet tube body is cylindrical and can be assembled and disassembled, and the lower end is an open bell mouth. A trimmed and thin reed is placed next to the mouthpiece of the ABS clarinet, and the player blows through the space between the reed and the mouthpiece. And with the proper pressure of the lower lip, the reed tip of the ABS clarinet vibrates. The air column in the ABS clarinet tube starts to vibrate, thus making the sound.

In addition to the key of E♭, the treble ABS clarinet is also available in the key of D, because E♭ instruments are used when dealing with key signatures with many sharps. The musician needs to press a large number of ABS clarinet changes (such as D major, E♭ instruments need to play 5 sharps, and A major needs to use 6 sharps or 6 flats), and it is very difficult to play. inconvenient. Therefore, manufacturers use the B♭ and A keys of the ABS clarinet, which are also applied to the soprano clarinet. But with the trend of unification of variant instruments, the D-key model of ABS clarinet has been gradually abandoned.

Through the above introduction and analysis of ABS clarinet, hope it helps you.
