Start and end your melody with the coloured keys. It will sound good all the time (thanks to black magic and music theory); so you can unleash your rythmic, your improvisation skills, your imagination are the only limit. You have your own mother play it and she will make a beautiful melody which resonates with her and everyone I had try this were shocked from how beautiful it sounds with very little effort. You can share with friends, maybe play together with two smartphones and accompagny each other.

The theory is explained on the website. The website is for smartphone (touch to play) and desktop (keys and mouse).

Next step of the development: accompagny any piece of music without playing any wrong notes by analyzing the music's scale and most resolving keys. Work in progress!

Check the settings for mysteries and untold surprises ;D

Reminder:

Hold Shift to vibrato

Hold Ctrl for bending

Hold Tab for arpeggio

Enjoy!
