Like the folk harp, the pedal harp is tuned like the white keys on a piano. However, it has seven pedals to let the harp player play music in different keys. Each pedal, named after the different musical notes, has three places. For the "A" pedal, the usual place makes all the "A" strings sound like a normal "A" ("A"-natural). The lower place makes all the "A" strings on the harp sound like "A"-flat, while the higher place makes all the "A" strings sound like "A"-sharp.
