Trombone
Together with vibrations from the player's lips, the trombone can play a wide range of notes. It sounds deeper than a trumpet and is usually said to be one of the bass clef instruments. Music is normally written in the bass clef, but some high parts maybe written in tenor clef. Some players have the music transposed into the treble clef. 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'.
