=16 tone equal temperament= ==Theory== 16-tone equal temperament is the division of the octave into sixteen narrow chromatic semitones. It can be thought of as a Diminished Temperament for it's 1/4 octave period. Also as a rough Slendro temperament with a supermajor second generator (250cents [ideally 233cents]), or as a Pelog or Mavila temperament generated by (fifths greater than 600 and less than 686 cents). The temperament could be popular for it's easy manageability of 150 cent intervals 3/4, 9/4 and 21/4-tones. The 25 cent difference in the steps can have a similar effect the scales of Olympos have with buried enharmonic genera. It can be It can be treated as 4 interwoven diminished seventh arpeggios, or as 2 interwoven 8-edo scales (narrow 11-limit whole tones which when stacked produce traditional 300 cent minor third intervals). 16-tone has the same stacked minor thirds diminished seventh scale/chord available in 12, and It is often cited that the most consonant chords involve the tritone. There are two minor seventh intervals, a harmonic seventh at step 13, a 7/4 ratio approximation, off by 3.5879 cents, followed by an undecimal 11/6 ratio or neutral seventh. The septimal intervals are the 9/4th tone or septimal semi diminished fourth (35/27 ratio) , septimal semi-augmented fifth (54/35), and the septimal harmonic seventh (7/4). The Undecimal intervals are the 3/4 tone or undecimal neutral second (12/11), and the 21/4 tone undecimal neutral seventh (11/6) One neat xenharmonic aspect of 16-tone is how the 11-limit whole tone scale using the neutral second, interlocks with the diminished scale, similar to the augmented scale and whole tone relationship in 12-tone (the whole tone divides the major third in 12, in 16-it's the minor third). In 16-tone, because of the 25 cent difference in the steps from 100 in 12-tone, a western "twelve tone ear" hears dissonance with more complexity and less familiarity than even 24-tone, yet within a more manageable number of tones and a strange familiarity - the diminished. Hence, why 16-tone is a truly Xenharmonic system. 16-edo Diatonic scales are dissonant because of the 25 cent raised superfourth in conjunction with the 25 cent subtracted fifth / poor 3/2 approximation. The septimal semi diminished fourth can be more desirable. Perhaps using Moment of Symmetry Scales an alternative temperament families like the "Anti-Diatonic" Mavila (which reverses step sizes of diatonic), Diminished, Happy, Rice, Grumpy, Mosh, Magic, Lemba, Cynder, and Decatonic can be more interesting and suitable.
