Music theory on a grid

Present a grid-based note layout to visualize whole steps, fifths, and major/minor scale shapes with enharmonic spellings and alternate semitone-shifted grids.

Excerpt from the original

Let me draw a grid: C D E F# G# A# F G A B C# D# C D E F# G# A# This is a whole step: C D This is a perfect fifth: C G The shape of C major is: C D E F G A B C The shape of E major is: E F# G# A B C# D# E The shape of A minor is: A B C D E F G A The shape of E minor is: E F# G A B C D E So how do you spell your intervals and scales? You know your whole steps. Whole steps on the C row: v Fb Gb Ab Bb C D E F# G# A# ^ Whole steps on the F row: v Cb Db Eb F G A B C# D# ^ If you shift the rows in such a way, so the diagonal step is a diatonic semitone instead of a fifth, you get a different kind of grid: C D E F# G# A# Db Eb F G A B C# D# Fb Gb Ab Bb C D E F# G# A# This kind of grid is especially
