Three Ways to Tune
Axiomatic
Pure Pythagorean ratios (2ⁿ·3ᵐ). Manual note selection. For solo tuning and interval study.
Tonal
Key-based context with alterations (♭♮♯) and sensitivity. For ensemble playing.
INSTRUMENT MODES
Unlocked — Auto-detects any Pythagorean note (voice, winds). Guitar/Violin/Viola/Cello/Bass — Auto-detects only the instrument's open strings. Pluck a string and watch it lock to the correct pitch.
What is Pythagorean tuning?
All frequencies are derived from two primes only: 2 and 3 — octaves (×2) and perfect fifths (×3/2). No equal temperament, no √2, no compromise. The Pythagorean comma (531441/524288 ≈ 23.46 cents) is the gap that emerges after 12 pure fifths — the difference that equal temperament hides, and that orchestral string players, woodwind players and singers have always corrected by ear.
