Drone Tone Tool is an app created by professional musicians and music educators providing high quality reference pitches with the rich overtones of real cellos. We encourage musicians of all abilities to experience the benefits of reference tone practice!

Why real cello drones?

There are many electronic tone generators, and while they are better than nothing, they lack complexity of overtones and can be painful to listen to. Our cello drones are pleasing to the ear, rich in overtones and contain layered octaves to facilitate practice in all registers.

Purpose and benefit of reference/drone tones:

A reference (or drone) tone provides a center of harmonic stability. Our ears are able to discern the way that multiple pitches interact while strengthening our internal sense of pitch. By playing with a movable pitch (instrument or voice) relative to a fixed pitch (drone tone) we can start to perceive truly consonant perfect intervals, and shades or colors within Major/Minor intervals. This heightened awareness of relative pitch leads to artistry through intonation.
