# Live demo

- http://learnharmony.net

# Instructions

- Open index.html

- Click on the piano keyboard (or press SPACE) to start playing

- Please note that you can click only the light blue buttons on the keyboard

- To stop, press SPACE

- Adjust the parameters as you like, toggles/sliders work while playing, while the others take effect on the first restart

# How does this work

- Plays chords according to predefined progressions, in various keys taken from the Circle of fifths

- It always starts from the key you pressed; if you use SPACE, it starts from A3 note (so the first key is A major or A minor)

- At times, shifts to a new key (using pivot chords) according to the rules chosen in the select field

- To modulate from a major key to its relative minor, it makes use of *ii - iv* correspondence or *iii - i* correspondence (in the latter case it doesn't switch to the strict relative key, but to its neighbouring key)

- To modulate form a minor key to its relative major, it makes use of *I - vi* correspondence or *VI - I* correspondence (in the latter case it doesn't switch to the strict relative key, but to its neighbouring key)

- At times, shifts to a new progression

- At times, makes a chord inversion (if Inv parameter is toggled on)

- Rhythm is generated randomly and changes at each restart
