Music is normally written in the bass clef, but some high parts maybe written in tenor clef.
sentences_after: A person who plays the trombone is called a trombonist. Some trombones have a valve which increases the range of available notes. The name 'trombone' comes from the Italian language and means 'large trumpet'.
