One cool thing about the harpejji: it's isomorphic. That means that the "shape" of a chord will be the same, everywhere on the playing surface. So, switching from playing in C major to D major just means moving your hands over one string. (Guitar and piano players know that it's more complex than that on their instruments.) |

A long time ago I asked on a music theory forum (probably on Usenet, but maybe on Reddit) what would be the best instrument to accompany learning music theory on. The answer given was the chromatic button accordion.
The buttons are in regular rows with alternating rows offset so that from any given button (except on the edges) there are 6 neighboring buttons arranged so that they are on the vertices of a hexagon. Moving diagonally through the hexagons moves in consecutive minor 2nds on one diagonal, major 2nds on another diagonal, and minor 3rds on the remaining diagonal.
On the harpejji each note position you'd have 2 directions that give minor 2nds, one that gives major 2nds, and one that gives minor 3rds, so should similar to the chromatic button accordion.
I wonder if in practice the offset rows of the accordion are easier or harder to deal with then the non-offset rows of the harpjji?
