Turn on "Tension as distance" to see which chords are at rest (near the middle) and which pull to resolve (out at the edge).
Click any chord to hear it; play then starts from that bar. Bars with two chords are split down the middle. Above the chart: ⏮ to the top, ◀ ▶ a bar at a time, ⏭ to the next section (or the last bar), and Loop.
