This is a generative jazz example with a style chooser: modal minor-nine harmony with major lifts, suspended returns, and grounded chord swells over a pedal bass, an ambient variant held long in a large room, a nordic cycle with brushes, a ballad in two, a bossa nova with its clave, swing over an AABA form with a walking bass, or a jazz blues with a shuffle. The lead, a jazz guitar, a flute, a harp, or a piano, improvises phrases that resolve to chord and colour tones on strong beats. Every run picks a new key and solo; listen in the browser, or render the same ensemble from the Node CLI.
