The topmost controller shows a scrollable list of available temperaments. Select temperament by scrolling the list vertically.
The horizontal list of notes may be used to redefine the intervals of the currently selected temperament. The selected tone becomes the tonic of the temperament, which corresponds to shifting the halftone intervals of the scale. Doing so redefines the frequency definition for most tones in the scale. Note that modifying the Equal Temperament is meaningless and therefore not possible.
The third list shows all 12 semitones of the selected temperament based on the current tonic and the A4 reference frequency.
A musical temperament, or a system of tuning, in which every pair of adjacent pitches is separated by the same interval. The most common temperament in modern music.
Was the most common meantone temperament in the sixteenth and seventeenth centuries.
Often called pure intonation, is a musical tuning in which the frequencies of notes are related by ratios of small whole numbers.
A musical tuning in which the frequency ratios of all intervals are based on the ratio 3:2, found in the harmonic series. This ratio, also known as the “pure” perfect fifth, is chosen because it is one of the most consonant and easiest to tune by ear.
