UNIVERSAL LADDER OF SOUNDS

Each wave increases from Mi to Fa to Sol, and as it does the force becomes less. One half of the cone is turned inside out. The notes therefore progress Re, Lab, Tib, Do, Sol, Mi Mib. The small dotted wave at the bottom denotes how the note pendulum sways as it swings along the wave. The NODE-MATTER indicates how the helix changes direction at the point of contact.
One ring is non-matter...
the other is matter...
