"Giant Steps" is a 1959 jazz standard by John Coltrane known for changing key often. It's considered a rite of passage in jazz to be able to improvise over it. Now you can improvise over this chord progression just by dragging your mouse up and down! - Click "Start improvising" when you're ready to jump in. - Then hold down your mouse and drag it up and down. You can also change the transposition of the chords (not the melody though, that's intentional). #games #jazz #/music
