Pythagorean Tuner

Pythagorean Tuner is a precision tuner for violinists, cellists, violists, bassists, and singers who play in true Pythagorean intonation, built on pure 3:2 perfect fifths. Unlike equal-tempered tuners, it places every sharp and flat at its true, distinct pitch, so a flat sits lower than its enharmonic sharp, just as string players hear it.
