The name nonagon is a prefix hybrid formation , from Latin ( nonus , "ninth" + gonon ), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

The ditone can be anywhere from 16 / 13 to 9 / 7 (3.55 to 4.35 semitones) and the microtones can be anything smaller than 1 semitone. [5] Some examples of enharmonic ...

For example, Seitenwechsel ("die Seiten wechseln" translates as "to exchange sides") mapped a triad on to its parallel minor or major, transforming C major to C minor and conversely. [7] Riemann's theory of transformations formed the basis for Neo-Riemannian theory , which expanded the idea of transformations beyond the basic tonal triads that ...
Major/minor compositions are musical compositions that begin in a major key and end in a minor key (generally the parallel minor), specifying the keynote (as C major/minor).). This is a very unusual form in tonal music, [1] [2] although examples became more common in the nineteenth century
