Streamlined workflow built for speed and accuracy under rehearsal pressure
ChoirPitch Studio is engineered by choir directors who needed a tool that works offline, protects sensitive singer data, and eliminates subscription fees. Version 1.0.2 is the result of 18 months of field testing with chamber ensembles, church choirs, and a cappella groups demanding total control over their vocal arrangements.
ChoirPitch Studio runs entirely on-device with zero internet dependency. Your singer roster, range data, and song library remain private and under your exclusive control. No cloud sync means no data leaks, no monthly fees, and no disruptions when WiFi drops mid-rehearsal.
The app's core transposition engine calculates safe key changes by comparing song requirements against each vocalist's mapped range. When you rotate the key selector, the algorithm instantly flags conflicts and displays alternative keys highlighted in orange. This eliminates guesswork and prevents voice strain from poorly chosen transpositions.
Warm-up card generation leverages your ensemble's center key to produce exercises that prepare singers for the exact pitch demands of your setlist. Breath holds, lip trills, hum slides, vowel scales, and arpeggios all auto-adjust to your choir's collective range, ensuring efficient vocal prep without wasted time on irrelevant drills.
Every feature designed to save directors time and protect singers from unsafe range assignments
Tap keys spanning C2 to C6 to define each singer's comfortable low and high notes. Visual rainbow gradient provides instant context while piano keys offer non-color reference for accessibility.
Rotate through all 12 chromatic keys with live preview of part start notes. Orange highlights show current selection, red warnings flag unsafe transpositions that exceed vocalist ranges.
Activate microphone input to measure how many cents a singer deviates from target pitch. App suggests better keys when consistent flat or sharp tendencies appear across multiple checks.
Organize rehearsal flow by reordering songs with touch gestures. Adjust tempo and count-in beats per song. Preview starting pitches with audio playback before printing materials.
Five exercise types – breath holds, lip trills, hum slides, vowel scales, major arpeggios – automatically center around your ensemble's current key to prepare voices for upcoming repertoire.
Generate printable materials with song titles, keys, tempos, count-in beats, and voice part start notes. Share via email or AirDrop with zero formatting hassle.
