PureCent Ensemble is an offline-first just-intonation and ensemble-blend studio for choir directors, a cappella captains, string-quartet coaches, wind-section leaders, and college ear-training cohorts.

Hear and see pure chord lock in seconds. Cent charts, voicing maps, and tuning order live on one workbench so sections blend before the downbeat—no internet and no accounts.

LIVE HARMONY WORKBENCH
Choose a root and chord quality (maj, min, dim, aug, sus, 7th, and extended). Lock concert pitch A4 at 415, 440, 442, or 443 Hz. Instantly read pure-interval cent offsets versus equal temperament for every voice.

VOICING TEMPLATES
Start from SATB, SSAA, TTBB, mixed chamber, string quartet, or brass quintet. Drag-reorder the part stack and apply octave shifts to match your ensemble.

TUNING-ORDER COACH
Step a clear sequence—root, fifth, third, then extensions. Spot beat-frequency risk on wide intervals and see pure third and sixth targets marked in cents.

REFERENCE DRONES
Play calculated tones per part with mute and solo toggles for sectional warm-ups. Everything runs on device.

CADENCES AND CLUSTERS
Seed packs cover plagal, authentic, deceptive, jazz ii–V–I, and barbershop swipe. Edit them into custom rehearsal packs you reuse night after night.

INTERVAL EAR-CHECK
Flash a written interval, select the quality you hear, and build a local weak-interval focus list—scored entirely on device.

ENSEMBLE PROFILES
Store name, default pitch, preferred voicing, and notes on device. Duplicate or archive profiles as your season changes.

COMPARE AND SHARE
Side-by-side just intonation versus equal temperament cards and printable-style cent tables for a single chord. Share plain text or CSV through the system share sheet.

BUILT FOR THE PODIUM
Stage-dark visual mode, large-type cent readouts, and left-handed control mirror. On-device persistence keeps ensembles, custom cadences, drill results, and preferences offline—no notifications and no cloud login.

PureCent Ensemble is a live harmony workbench, not a practice log. Lock pitch, lock temperament, lock blend.
