meantone temperament

Meantone temperament is a musical temperament, which is a system of musical tuning. In general, a meantone is constructed the same way as Pythagorean tuning, as a stack of perfect fifths, but in meantone, each fifth is narrow compared to the ratio 2^7/12:1 used in 12 equal temperament. The meantone temperament:

• generates all non-octave intervals from a stack of tempered perfect fifths; and
• by choosing an appropriate size for major and minor thirds, tempers the syntonic comma to unison.
