The Mavila Experiments - 25-EDO Version by Mike Battaglia

==25-EDO VERSION==

These musical examples are tuned to what is known as "mavila" temperament. It is named after the Mavila village of the Chopi people in southern Mozambique, where this tuning system was first discovered by Kraig Grady.

By virtue of the structure of this unique tuning, every existing piece of common practice music has a "shadow" equivalent rendition in mavila. That is, when Bach wrote Fur Elise, he actually wrote two songs - the one that you know, and the anti-diatonic equivalent in mavila temperament. It's only that the anti-diatonic versions have never been heard before.

Mavila is a tuning system whereby four stacked perfect fifths, rather than getting you to a major third, gets you to a minor third - meaning that the fifths are flat. Conversely, four stacked perfect fourths gets you to a major third, rather than a minor third. This has some very strange implications for music. The mavila diatonic scale is similar to the normal diatonic scale - except interval classes are flipped. Wherever there was a major third, you'll find a minor third, and vice versa. Half steps become whole steps and whole steps become half steps (closer to neutral second range, however). When you sharpen the leading tone in minor, you end up sharpening it down instead, meaning you flatten it. Also, minor is now major - you end up with three parallel natural/harmonic/melodic major scales, and only one minor scale. Instead of a diminished triad in the major scale, there is now an augmented triad.

In these examples, the chosen mavila temperament is 25-equal, which was chosen so as to make all of the intervals in the mavila anti-diatonic scale to be as "distinct" from one another as possible, albeit at the sake of accuracy in approximating the harmonic series. 23-equal gains harmonic accuracy at the cost of categorical clarity, and 16-equal mediates between the two.

A special thanks goes out to Graham Breed; his custom Lilypond code and several weeks worth of gchat discussion are what made all of this possible.
