ChoirPitch Studio

Stop guessing whether a song fits your choir. ChoirPitch Studio is an offline-first vocal range and song-key workbench for choir directors, vocal coaches, and small a cappella groups.

Instead of doing mental math, you build an ensemble of voice parts and singers. See each singer's range as a colored lane on an interactive piano, and transpose any stored song to a key that fits your group.

FEATURES

• Choir setup Set up your choir with up to 8 voice parts (Soprano 1/2, Alto, Tenor, Baritone, Bass). Assign each part a color and a default vocal range, then add singers with their own comfortable range on the piano.

• Song library Start from 12 included public-domain folk and hymn songs, or build your own. Each song stores title, time signature, tempo, original key, and optional per-part starting notes.

• Range Lab See every singer's range at a glance. Tap a singer to highlight their range and get an auto-score for how well the current song key fits that voice. Sing a short test phrase into the microphone—the app compares the detected tone to the target starting note, shows cents of deviation, and suggests nearby keys that sit closer to the singer's comfort zone.

• Transpose & audition Transpose any song to a new key in one tap. All part start notes and chord symbols update immediately, with a highlighted 'range trouble' warning when a part goes too high or too low. Listen to each part with synthesized reference tones: choose a pure sine wave or a soft organ timbre, set the master volume, and mute individual parts before rehearsal.

• Rehearsal setlists Arrange songs into a rehearsal setlist by dragging rows. Set per-song tempo and count-in beats, and get an instant estimated rehearsal time. Export a printable PDF card with start notes and member cues.

• Warm-up generator Create a warm-up card from 12 built-in patterns—breath holds, arpeggios, vowel scales, range slides—automatically placed in the ensemble's current key and tailored to the voice parts in the setlist.

ChoirPitch Studio works entirely offline. No subscription. Just the tools you need to start every rehearsal in tune.
