Hohner Pro Harp MS Eb OverviewKnown for a smooth, warm tone, the Pro Harp has the same sleek black non-stick covers as the Cross Harp, with a polished plastic comb and standard thickness reedplates.
The reeds of Diatonic Harmonicas produce the notes of the scale to which they are tuned. For example, a diatonic harmonica tuned to the key of C would produce the natural notes of the C scale without sharps and flats (picture the white keys on a piano, without the black keys). Each hole has two reeds; one plays when breath is exhaled (blow) and the other when inhaled (draw). The individual reeds are each tuned to play a different note on the scale.
