Drone Tone — Tonic Drone

Drone Tone is a focused, sample-accurate drone generator built for singers, instrumentalists, and ear-training students. Pick a tonic. Pick an octave. Hit play. You get a clean, steady reference pitch you can sing over, tune to, or use to drill intervals — no clutter, no popups, no upsells. KEY FEATURES • Sample-accurate sine, triangle, square and saw waveforms with light vibrato for a natural feel • 12 tonics across 5 octaves, switch keys without stopping the tone • Practice mode for intervals: hold the root, see the target note, time your session • Session timer and saved practice records so you can track time on each key • Background audio so the drone keeps going while you practice from charts or sheet music • Single-screen layout, large controls, no account required DESIGNED FOR PRACTICE Whether you are warming up your voice, drilling solfège, tuning a stringed instrument, or running raga and modal practice against a tonic, Drone Tone stays out of the way and just holds the pitch. PRIVACY No tracking. No accounts. Your practice records live on your device.
