Chord progression tool

I will ask some feedbacks to my little cousin 8 years old and I will tell you his point of view.

It seems that some sonic pi users are great children for ever :blush:

By the way a little joke :
What is the difference between a jazz band and a rock band ?
A jazz band it’s 2000 chords by song and 3 people into the public. You guess for the rock band ?

Cheers and keep sharing friens your amazing scripts !
