Chromatic Block System — Piano Workspace

User Manual

Use the Scale Key at the bottom to establish your root tonic.
Click any key on the interactive piano to trigger playback; observe the color-coded strip to identify roles (Block 1, Gap, Block 2).
Select a highlighted scale note to lock it into Note Inspection for metadata and functional roles.

Arc Structures: Horizontal subsets carved from the master NBS (Diatonic, Pentatonic, Tritonic ii-V-I cadences).
Octave Structures: Vertical harmonies dictating how notes stack (Triads, Quartals, Symmetric divisions, and Shells).
Audition any structural footprint in real-time by clicking the Block or Arp buttons.

Octave structures utilize two bracketed coordinate systems:

Interval Signature (e.g., [4, 3, 5]): Maps vertical distance in semitones. Values always sum to 12.
CoF Signature (e.g., [+4, -3, -1]): Maps the horizontal vector along the circle of fifths (+ is clockwise, - is counter-clockwise). Vectors sum to 0.
