The trumpet has seven standard keys that allow the player to change the pitch of the notes. The keys are:
* F♯
* G
* A
* Bb
* C
* D
* E
In addition to the seven standard keys, there are also a number of auxiliary keys that can be used to play higher and lower notes. The most common auxiliary keys are:
* High F♯
* High G
* High A
* High Bb
* Low F♯
* Low G
* Low A
The range of the trumpet can be extended by using different combinations of keys and auxiliary keys. For example, the highest note that can be played on a trumpet with all of the standard keys and auxiliary keys is the G7, which is the third G above middle C. The lowest note that can be played on a trumpet with all of the standard keys and auxiliary keys is the Bb2, which is the second Bb below middle C.
The trumpet is a versatile instrument that can be used in a variety of genres of music. It is commonly used in jazz, classical music, and marching bands. The trumpet is also a popular instrument for solo performances.
