DroneTones: Pitch Reference

A steady, warm cello drone to help you play in tune. Pick a note, press play, and tune your ear to a rock-solid reference pitch — for any instrument or voice. Practicing with a drone is one of the most effective ways to fix intonation. Instead of chasing a needle on a tuner, you train your ear against a continuous, sustained reference tone and learn what "in tune" actually feels like. Scales, long tones, improvisation, warm-ups — a drone makes all of it sharper. DroneTones gives you a rich, natural cello timbre across all 12 chromatic notes, in three octave registers, so the drone sits comfortably under whatever you play or sing. WHO IT'S FOR • Strings — violin, viola, cello and bass intonation • Voice & choir — match pitch and hold a tonal center • Brass & woodwinds — tune long tones against a reference • Indian classical — use it as a simple tanpura or shruti box drone • Bagpipes, hurdy-gurdy and other drone-based traditions • Any musician working on playing in tune FEATURES • Warm, natural cello drone tones • All 12 chromatic notes, in low, mid and high registers • Sustained playback that keeps going as long as you practice • Clean, distraction-free interface — pick a note and play • Works fully offline, with no account and no sign-in • Every note and register is unlocked — no time limits, no lock-outs • An optional tip jar is the only in-app purchase, and it unlocks nothing WHY A DRONE BEATS A TUNER A tuner tells you that a note was wrong after you played it. A drone lets you hear it while you play. Holding a scale, an interval or a long tone against a steady reference pitch is how ear training actually happens — and it's how string players, singers and wind players have practiced intonation for generations.
