they know the words

Play it a tune and a congregation sings it back: twelve people and a reed organ in a cold church, late, flat and quavering. Each cup makes them younger. At the seventh they turn, cold and perfect, a note ahead of you. Dawn takes them one by one.
Turn a knob: drag it or tap either side of it, roll the wheel over it or use the arrow keys; a double click puts it back. CUP and DAWN are buttons to press: a cup, and the sunrise. The patches step on by themselves until you touch anything.

Everything FAITHFUL does here is its engine as designed, running in your browser. The sequencer and the drums are a stand-in rack.
They pick it up as it repeats. Once they've heard the same notes at the same gaps twice running they know it, and drag less.
