Chord builder

Build chords, choose the inversion and the bass note, and hear them right away. Arrange the chords into bars and loop the progression with a band: steel-string or nylon guitar, clean or distorted electric guitar, piano, electric piano, bass and drums, each with its own groove, volume and pan. Save your progressions by name and use swing to give the eighth notes some bounce. The harmonic field shows the chords that belong to the chosen key.
