Page "Pitch pipe" Paragraph 5

Some pitch pipes are intended for tuning string instruments, and only provide reeds for notes appropriate to a particular instrument.

Chromatic pitch pipes are favored by a cappella singers and timpanists.

Chromatic pipes most often provide thirteen pitches, each a half step above the previous.

By providing all of the notes of a single octave, a singer can start in any key called for in Western music.

Different pipes are available for men and women due to the differences in vocal range: male singers most often use F-F pipes, while female singers favor C-C pipes.

However, it is particularly notable that the Men's pipe in F is pitched higher than the Women's C pipe.

Pipes in other keys are available, but are much more rare.
