"wasserklavier" is a piano piece by Luciano Berio.

• The score.
• A Numula program that renders it.
• The rendition with nuance
• The rendition without nuance

For reference, a couple of human performances:

• By me
• By Hélène Grimaud

Program notes:

• The score has 6 lines, so for clarity I divided things into functions accordingly. I tagged notes with "line1", "line2" etc. so that I could select them in nuance selector functions.
• The music divides pretty cleanly into left and right hands parts, each of which is mostly sequential (i.e. has no overlapping notes). I tagged the RH notes with "rh", using the "(rh" notation, so that I could roll RH and LH notes separately.
• I emphasize top notes (those tagged "top") fairly strongly: 1.2. The synthesizer I'm using (Pianoteq) seems to play lower notes louder.
• I tagged a few notes with "more" and "less", and changed their volume accordingly.
• I added a normally-distributed time offset with stddev .015 sec to give it a human feel. This makes a surprisingly big difference.
• I didn't use pedal, either sustain or soft, but I probably should.
