Tell Chordseed the mood you want and it suggests the next chord, plays it on real instruments, shows you where to put your fingers and explains why it works.
Works now in any browser on computer, tablet and phone. No download needed.
Chordseed is for anyone who plays a little and wants to write their own music, without needing to know theory first.
Pick happy, melancholic, epic, dreamy, tense or dark. Chordseed ranks the chords that fit, with a short reason for each one.
Piano, acoustic and electric guitar, strings, flute and synth, with drums and bass in your style: pop, rock, neo-soul, bossa, metal and more.
Guitar shapes, piano keys, violin and flute fingerings for every chord, plus famous songs that use the same progression.
Turn your progression into parts, put them in order and play the whole song with a band behind you.
Seven short lessons take you from your first note to understanding why chords work. Each one explains the idea in plain words, lets you hear it and ends with a quick question.
“I’m Lumen. I keep the light on while you find your way through the forest of chords.”
Lumen walks you through every lesson, explains each part of the app when you turn on Learn mode, and celebrates with you when you get it right.
