Melody pattern

Arpeggio

An arpeggio plays the notes of a chord one after another instead of all at once, here climbing on every sixteenth note, all 16 steps of 16. Every note belongs to the chord, so it always fits, and it turns a held chord into a running pattern: the shimmer of synthwave, trance and a lot of film music.

Also called arp, arpeggiated chords, broken chord.

Faded lanes are a guide: they are there so the pattern has something to sit against. The loop runs over four chords, Am7, Fmaj7, Cmaj7, G7, one bar each. Tap any box to change it.

Tap any note to take it out. The notes after it shift along, because each hit plays the next note of the chord: an arpeggio counts hits, not steps.

How it works

Each chord here has four notes: the root, the third, the fifth and the seventh. The arpeggio climbs through them, starts again and climbs again, four times per bar. When the chord changes, the same shape moves to the new notes on its own.

Synthesizers have a button for this, the arpeggiator: hold a chord and it plays the notes in turn, up, down or up and down, at a speed locked to the tempo.
