How a ground works
A ground is a short bass line repeated under changing music above it. Chaconnes and passacaglias are triple-time grounds; the passamezzo, romanesca and folia are older dance basses.
What it is
Long before the loop, there was the ground: a repeating bass line that players built on, varied and danced over for hours. Groundwork brings that tradition into your studio. Pick a ground, a dance or a continuo pattern, choose any key, and Groundwork generates the bass and the chords above it, ready to drag into your session.
It doesn’t stop at the Baroque. Groundwork also covers jazz, blues and pop progressions and son montunos. When you’re ready, you can build a ground of your own.
