Enum tune::temperament::TemperamentType

pub enum TemperamentType {
    Meantone,
    Porcupine,
}

Variants

Meantone

Octave-reduced temperament treating 4 fifths to be equal to one major third.

The major third can be divided into two equal parts which form the natural or primary steps of the scale.

The note names are derived from the genchain of fifths [ … Bb F C G D A E B F# … ]. This results in standard music notation with G at one fifth above C and D at two fifths == 1/2 major third == 1 primary step above C.

Porcupine

Octave-reduced temperament treating 3 major thirds to be equal to 5 fifths.

This temperament is best described in terms of primary steps three of which form a fourth. A primary step can formally be considered a minor second but in terms of just ratios may be closer to a major second.

The note names are derived from the genchain of primary steps [ … G# A B C D E F G Ab … ]. In contrast to meantone, the intervals E-F and F-G have the same size of one primary step while G-A is different, usually larger.
