What:

Insights into the final (fourth) movement of a string quartet (the tenth).

How:

Extended just intonation, interpreting all musical intervals (melodic as well as harmonic) as small whole-numbered vibration ratios, a process here applied to major and minor (mirror inversion of major) modal tonalities.

Recomposing samples of successive contrapuntal styles: :a “what if” revisionism applied to successive stages in harmonic/melodic stylistic change; demonstrated by a set of “Enigma” (theme not given) variations.

The Enigma theme revealed, providing climax and musical commentary.

Why:

To provide intelligibility via a “how-to guide” for maximum grasp of an as yet unknown system of music composition.
