Upper Structure Triad Generator

How To Use:
(1) Choose default UST to apply for each chord quality, at below console.

(2) Write song in the text area. (default : "Autumn Leaves")
- Write chords with measure separator " | ".
- In case multiple chords are in a measure (1, 2 or 4), use comma " , " between chords.
- Available chord types are listed in the right table.
- If you want to specify UST, you can do it by adding option listed in the right table.
- If option is given, that specific chord uses given UST, other chords still follow default UST set in below console.

(3) You can choose the highest & lowest notes of left hand comping.

(4) Press "Generate". Have FUN :)

*Unusual enharmonic chord or chord with double sharp/flat notes may give weird notation.
