What is the highest note in the trombone range?

The highest note commonly recognized in the trombone's range is F5. This range can vary based on the specific type of trombone being played, such as the bass trombone or the alto trombone, but for the most widely used tenor trombone, F5 is considered to be a practical limit for much of the music that is performed.

F5 can be considered within the practical playing range for many trombone players, allowing them to execute various pieces that require higher registers. While higher notes exist and can be played, F5 is often seen as the upper threshold for typical playing scenarios.

The other notes, such as C5, G5, and A5, while they may be part of the overall range for advanced players or in specific contexts, are less frequently specified as limitations in terms of practical performance on the tenor trombone. Therefore, F5 stands as the highest reliable note for most trombone players and repertoire.
