How Does a Trumpet Function?

The trumpet is the highest-pitched member of the brass family of instruments. Trumpets have a range of about three-and-a-half octaves, from F below the treble clef (F3) staff to C two octaves above the treble clef (C7). Some trumpet players have the ability to play even higher or lower. The trumpet is capable of playing these pitches because of the acoustic principles and mechanical construction.
