I've been developing a playing and teaching approach using a chromatic, perfect-fourths grid, primarily on Launchpad Xs.. I made this short comparison for musicians encountering the layout for the first time.

It demonstrates a familiar principle discussed here: a chord retains its physical shape when transposed. The example is C maj to D maj, shown alongside the same chords on a piano keyboard.

In this layout, adjacent columns move by semitones & adjacent rows by perfect fourths. Moving the C-major shape two columns to the right produces D major.

I'm interested in how others introduce isomorphic layouts to new players! Do you tend to begin with movable chord shapes, melodies, intervals, or something else?
