  let bars = 4
      key = "8"
      righthand = "[[4 -3] [0 _ _ _ _ _ 0]] [[-3, -8] [7 5 4 0]]"
      lefthand = "[0 9 12 16] [4 12 16 19] [5 12 17 19] [2 12 17 16]"
  d1 $ slow bars
     $ stack [
         n (righthand + key + "<24 36>/2"),
         n (lefthand + key)
       ]
     # s "midi"
     # octave "3"
     # velocity "0.3 0.5 0.8 0.9"
     # sustain "[2 0.7]*4"

This is super cool. Could you explain what is actually meant by the code for the righthand and how that is combined with the lefthand using this stack concept? This tidal language seems very cool.

@davispolito stack plays a list of patterns simultaneously, and lefthand and righthand refer to the separate piano parts.

so what would be [[4 -3] [0 _ _ _ _ _ 0 ]] vs [4 -3 0 0] ?
I assume "_" is a rest. are the duration values based on size of the array? i.e. for an array [0, 1, 2, ... , n] each note would get a duration of 1/n.
And then what is the difference between [a b] and [a, b]

Note: To get this working locally after installing TidalCycles follow the SuperDirt MIDI Tutorial to define a MIDI Out for SuperCollider named midi.

In my case I defined MIDI Out to point to a VIRTUAL MIDI-Out Host running on my laptop. I was then able to receive MIDI events over Web MIDI and play audio via Web Audio in a browser. :)
