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.

My husband and I are returning in November also. November is my favorite month to visit New Orleans followed by March or April. I agree with the other posters though the weather can be iffy. We have been there then when it was 88 degrees, one year it was actually cold and rainy and a couple of years it was in the 70s.
