No MIDI keyboard? Play with your computer keys: bottom rows are the lower octave, top rows the higher one. Hold Shift to sustain. ← → octave, ↑ ↓ semitone.

Notes swell in rather than striking, like voices in a candlelit chapel. Hold three or four together and let them move; this is a sound for slow music, not fast playing.
