Diatonic Single Reed Models
These models include some of the most popular harmonicas and are used in Blues, Folk, Country, and Rock. All feature reeds which are tuned to produce the natural notes of the scale without any additional sharps and flats. Each hole has a blow reed and a draw reed, each tuned to a different note on the scale. Most are ten hole instruments with the four middle holes comprising a complete eight note octave, and the holes on either side extending the scale and permitting chord playing. These models are capable of producing the expressive effects of bending and overblowing.
