The AI does not write your song. You do.
The AI extends what you give it. The more you put in, the better the return.
Minimum to get anything useful: 3 chords, a section, a BPM, a feel. To get something worth using: full structure, lyric fragments, chord progression, drum feel, key and scale, a title, an emotional direction.
This is not AI generation. This is AI collaboration.
The song is yours. The AI is the session musician who reads your chart.
Minimum 3 chords. More gives the AI more to work with.
This is what you have built. This is what the AI will read.
Go back and add more if it feels thin. The AI cannot invent what is not there.

The AI is reading your foundation. It will extend — not replace.
Playback uses your chords and BPM. Drums use Web Audio synthesis. This is a rough arrangement sketch — not a demo recording.

Ear Training
Listen to the interval. Identify it. This is how McCartney, Gilmour, and every great melodicist trained their ears.
Select a root and scale to see every note across all four strings. Purple dots = root notes. These are the same notes you see on Piano — same theory, different layout.
The piano is the universal theory reference. Every scale, every mode, every chord is visible on the keys. What you see here is the same notes on your bass and guitar — different layout, same music.
