We have checked Chord Nebula 158 times since 15 Sept 2026, and it answered every time. Its visible text has not changed since we started watching.

What it does

Connect a MIDI keyboard or a MIDI-capable phone app, then pick a genre, scale, key and level. Notes and chords fall from the top of the play area and you play each one in time before it lands. The genre sets which progressions and scales you get: pop and classical stay in major and minor, rock and blues add mixolydian, jazz and funk add dorian, and EDM adds phrygian.
