    Select Temperament

    The topmost controller shows a scrollable list of available temperaments. Select temperament by scrolling the list vertically.

    Modulate Temperament

    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.

    Temperament Definition

    The third list shows all 12 semitones of the selected temperament based on the current tonic and the A4 reference frequency.

Temperament Collection

The preset collection of temperaments includes the following temperaments.

  • circle
    Equal Temperament

    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.

  • circle
    1/4-Comma Meantone

    Was the most common meantone temperament in the sixteenth and seventeenth centuries.

  • circle
    Just Intonation

    Often called pure intonation, is a musical tuning in which the frequencies of notes are related by ratios of small whole numbers.

  • circle
    Pythagorean Temperament

    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.

Remove Temperaments

Scroll the list at the top and select the temperament that you want to remove. Click the trashcan button to remove it. Note that any temperament from the preset collection cannot be removed.

Import Temperaments

You may define your own 12 tone scale temperament. All you have to do is create a text file that defines the temperament. The definition of the temperament has to follow a few rules outlined in the File Format section. Use the file sharing service in iTunes to actually import your temperament to Concert Pitch. Connect your device to a computer with iTunes installed and in iTunes scroll down until you find the File Sharing section. Click on the Concert-Pitch app to activate it and upload your temperament in the Document section.
