Pedal tones are special notes in the harmonic series of cylindrical-bore brass instruments. A pedal tone has the pitch of its harmonic series' fundamental tone. Its name comes from the pedal keyboard pedals of a pipe organ, which are used to play 16' and 32' sub-bass notes. Cylindrical brasses do not naturally vibrate at this frequency. A closed cylinder vibrates at only the odd members of its harmonic series.
