Often the timbres of different woodwind instrument registers tend to be markedly different. *Example 2: The

the notes from ( written) G4 or A4 to B4 sometimes are regarded as a separate "throat register", even though both they and the notes from F4 down are produced using the instrument's lowest normal mode; the timbre of the throat notes differs, and the throat register's fingerings also are distinctive, using special keys and not the standard tone holes used for other notes. The register in which an instrument plays, or in which a part is written, affects the quality of sound or timbre. Register is also used structurally in musical form, with the climax of a piece usually being in the highest register of that piece. Often, serial and other pieces will use fixed register, allowing a pitch class to be expressed through only one pitch.
