What that means in practice is that to play a concert F major on a tenor saxophone, the player should play a G major on the score. When a C is played on a tenor saxophone, however, the actual pitch produced corresponds to a B♭ on a piano, and in the case of an alto saxophone, playing a C actually produces an E♭. Tenor saxophones are tuned to B♭, and alto saxophones are tuned to E♭, but when playing the same note on a score, the fingerings are the same.

Transposing instruments produce sounds different from those in the score and those produced by non-transposing instruments (the piano is the standard for actual or "concert" pitch). Because the saxophone is a transposing instrument, when changing from one instrument to another, such as from an alto to a tenor, playing the same score will produce different actual sounds.
