Gacha Chord: Progression Maker

Write a song in bed. Transcribe one on the train.

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. Record it as a video, or read it while you play


■ 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.


■ 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


■ 3. RECORD IT AS A VIDEO, OR READ IT WHILE YOU PLAY

Post it the moment it lands.

The playing chord can fill the middle of the screen: the song title, the key you are in, the degree, the chord name, the image you attached and the note you left on that chord, all on one screen. Record your screen and the short video is done.

Leave it looping on the big display and it doubles as your chart while you play.
