Pythagorean Tuner is a precision tuning application designed for string musicians and singers. It focuses on true Pythagorean intonation, using pure 3:2 perfect fifths to achieve distinct pitches for sharps and flats.
Unlike equal-tempered tuners, Pythagorean Tuner places each sharp and flat at its true, distinct pitch. This means a flat will sound lower than its enharmonic sharp, mirroring how string players often perceive these notes.
This tuner is ideal for violinists, cellists, violists, and bassists. It is also beneficial for singers who aim for precise intonation in their vocal performances.
