Click on the Chords in the Circle to listen to them. Every time you click on one of them, there will be new suggestions for new chords that are related to them. The relationships of the chords are often non functional and typical of romantic harmony. If you click on the middle chord, you can add a new chord to the suggestions. (For example: C maj7 or Db 7b5. The space in between is important.) Turbo mode is recommended.
