If you have a chance to attend an orchestra concert anytime soon and one of the pieces on the program calls for a harp, make sure to watch the harpist’s feet. They’ll be busy. The modern concert harp has forty seven strings, but it also has seven foot pedals, each of which controls one set of strings for each note of the scale. The A pedal, for example, controls all the A strings on the harp, and can change their length so that they sound A-natural or A-sharp or A-flat. As they play, harpists have to set and reset their pedals constantly—and quickly—to prepare for the notes that are coming up.
Meanwhile, shifting your view from the feet to the hands, you may, if you’re sharp, detect an interesting phenomenon: harpists don’t use their pinkies. Since it’s the weakest finger, and since on the harp it provides no reach advantage—the ring finger stretches farther—the pinkie is just along for the ride.
