Write a song in bed. Transcribe one on the train. Then pick up your guitar and play it. Gacha Chord makes chord progressions simple: you just tap the chords you want. No keyboard, no DAW, so the idea gets built wherever you happen to be. 1. Let it suggest, and write in bed 2. Write down what you transcribe 3. Play it with guitar chord charts โ–  1. LET IT SUGGEST, AND WRITE IN BED The progression you would never have thought of. Place a chord and it offers what could come next: a weighted gacha built on functional harmony. Three safe picks and two adventurous ones. Every suggestion carries a one-line reason. Dominant resolutions, secondary dominants, tritone substitutions, modal interchange, passing diminished chords, chromatic mediants. A star marks the ones that connect most naturally. Press and hold a chord to swap it for a substitute. The further a chord strays from the key, the louder its color, so you can see how far you have wandered. โ–  2. WRITE DOWN WHAT YOU TRANSCRIBE Pull a song apart in the gaps of your day. It works just as well as a notebook for the chords you write or pick up by ear. - Scale degrees and real chord names, side by side. Change the key and the whole progression moves with it - Build the exact voicing: tensions, altered fifths, inversions, slash chords, octaves - Split the progression into verse and chorus, and transpose section by section - See dominant motion, ii-V pairs, pivot chords and the source of borrowed chords marked on the progression - Find saved progressions by name or tag โ–  3. PLAY IT WITH GUITAR CHORD CHARTS Your chart for singing along. In the section view, switch every chord to a guitar chord chart (Pro). Choose between open and barre shapes, and the shape you pick is saved with the song. Hit the play button at the bottom to loop the progression. The chord that is playing lights up, so you can follow along in time. Great for practice, or as a cheat sheet on stage. โ–  GACHA CHORD PRO (ONE-TIME PURCHASE) A single purchase unlocks everything below. There is no monthly fee. - Unlimited saved progressions - Unlimited favorite chords - Recording: hum the melody in your head and play it back over the chords - Arpeggio playback - Notes and an image on a saved progression - MIDI export (opens straight in GarageBand, Logic and others) - Guitar chord charts, with both open and barre shapes - iCloud Backup, with or without your recordings.
