Q: What is a valved diatonic?

A: Suzuki markets the Promaster diatonic harmonica with and without valves,
also known as windsavers. By adding valves to certain holes it is possible
to obtain notes though bending that are not usually available on a
diatonic. Diatonic players interested in achieving chromatic tones usually
focus on the valved or overblow technique (but not both) since the note
placement for the accidentals ends up at different holes. Also, the choice
is made between the techniques by timbre aesthetic preference — some like
the valve bent sound better than the overblow, others like the color or the
overblow.
