The scale setting used on the 10-hole harmonica, also known as the blues harp, is called tuning.
The most common scale setting is called Richter tuning, which is the default tuning for most 10-hole harmonicas. Generally, most songs can be played using this tuning and a technique called bending, which lowers the pitch. However, some songs require the use plenty of more advanced techniques, including bending.
For this reason, various special tunings with scale settings have been devised that allow certain songs to be played without requiring the use of advanced playing techniques. However, even if you want to try playing in a special tuning, it is often difficult to obtain a harmonica that is already tuned in this way.
The iPhone harmonica app “CC Harp” has a variety of built-in tunings, as listed below. Most of the tuning names listed are popular names, but some are unique to the app.
Below the tuning name, the scale (note names) for the key of C and the blow-draw pattern are shown.
