Description

Hear your ensemble in tune: every voice, every chord, pure intervals.

Choir Tuner listens to your whole ensemble at once. Sing or play a chord with two, three or four voices and see every voice as its own column: the note, how far it is from pure (just) intonation above the chord root, and its distance from piano tuning. WHY JUST INTONATION A major third that is "right" on the piano is 14 cents too wide for a ringing chord. Choir Tuner measures each voice against the root as your basses actually sing it, so a director sees at a glance which voice should move, and which way. FEATURES • Detects 2–4 simultaneous voices, C2 to C6 • Names the chord and its inversion: major, minor, diminished, augmented, sus, sixths and sevenths • Cents vs just, equal or Pythagorean tuning; dominant seventh as 7/4 or 16/9 • Intervals between voices, consonant or dissonant • Reference drone: a soft organ note, fifth, chord, or the last chord you sang re-tuned pure • Single-voice mode for maximum precision • Music-stand view: giant type readable from 2–3 metres, great on a tablet • Hold the chord: a 5-second stability score with pitch drift, and a local warm-up history • Reference pitch A4 415–466 Hz • Note names A B C, A H C or Do Re Mi · 71 languages · dark and light theme PRIVATE BY DESIGN Free, offline, no ads, no in-app purchases, no account. The microphone is analysed on your device and never recorded or sent. For choirs, a cappella groups, barbershop quartets, vocal ensembles and string quartets. Made by Felice Marra Music Studios.
