Homechord

Homechord is a chord-progression workbench in the spirit of a Real Book.
Pick a key, tap chords to hear them instantly on a faithful synth voice, and watch harmonic function — tonic, subdominant, dominant — colour the path home.
• Build: diatonic palette, suggestions with coach lines, tempo and feel, loop and arpeggio.
• Chart: print-ready chord chart with piano keyboard and guitar diagrams, capo and easier shapes, copy as text.
• Train: ear-training rounds on genre banks, level-gated, streaks.
• Two themes — Day Paper and Warm Night — following the OS or your toggle.

Works offline. No account, no ads, no tracking — your progressions stay on your device. Share a progression with a link; it opens ready to play.
