This is a visual representation of the first 3 minutes of the 2nd Movement of Beethoven’s 7th Symphony. The idea is that the 12 chromatic notes of the scale are represented by the 12 points of a circle like a clock. The notes spiral forward and out as the notes get higher in pitch. The octaves line up so two notes at 12 o’clock are both C but one may be one cycle down the spiral and so an octave lower.
The Stringed instruments are represented by yellow, the Winds by white and the Horns by purple.
The common patterns in this piece are the chord shapes A minor, E major, G, C, B, and Bm. Minor chords make a triangle 3-4-5, for example, Am is A, up 3 notes to C, up 4 to E and up 5 to return to A. Major is a 4-3-5 triangle. Interestingly, as Pythagoras is known as the Father of Music, this echoes the Pythagoraen Theorem. The Chromatic Spiral also echoes Goethe’s and Newton’s illustrations mapping a colour wheel to musical notes. The difference here is that those three characters only worked with 7 notes of the octave and 7 colours. Here is the same idea updated to the 12 chromatic notes and displaying the 3 primary colours, the 3 secondary colours and 6 tertiary.
