A large circle is shown for the MUSIC PROGRESSION -FULL.
In it is a spiral with MUSIC PROGRESSION PART circles.
Each music progression part consists of several RHYTHM
SECTION circles in a spiral. As you add rythm sections, the
spiral fits them
The rhythm section circle consists of several spirals with
RHYTHM PART circles each with 24 angular marks. You can
draw in your basic rhythm or sing it. You can add a circles

longer (and wider) mark on the note location.
Initial entry is done by microphone. You sing in or tap, and

In the center you can: choose to change the scale (with our

without changing the notation location on the circles),
transform (turning the circles - so that the notation
location is now in a different location), select musical
ALL spirals support: Edit, delete, cut, copy and paste.
If it turns out that clicks move things around
unintentionally the spirals should also support: Protect /
The spirals can be rotated and made longer or shorter, so
that things "make sense" to the user.
OK Here goes, I'll spend an hour on the drawings.
