[Western] Music is the dynamic interplay of Twelve with itself and Time;
Thirteen completes the octave;
Seven defines a standard scale,
Eight completes such a scale.

Seven is Six around One
Eight is Four times Two.
Fyve is the number if Life; four around One;

Four is Three around One
Three is One flanked Evenly

Two is what is become of One

One is where it all begins.
