Etudes for tidal

@kit-christopher and I were chatting recently, and decided we are going to try and golf some etudes for tidal to help improve our real time melody composition/syntax/shortcut game.

I think it'd be great to see how other people see these patterns represented in code too, we might be able to develop some new methods/shortcuts etc :slight_smile:

I'm keeping my results here:

Starting simple - First 8 bars of "In May" by Franz Behr:

-- In May - Franz Behr   
d1  $ stack [
        arp "down" $
            n "<c6'maj d6 c6'maj d6 [c6 d6 e6] [f6 e6 d6] [e6 d6 c6] d6>" 
        , arp "up" $
            n "<[c5'maj] [b4,f,g]>"
    ] # s "superpiano"

[edit] golfed it a bit, fixed a mistake

Thankyou! I will - I got all gee'd up to do a few of these then my spare time ran out...

I'll take a look at it this week hopefully :slight_smile:

5 
note (scale "major"
     $ cat [ cat $ walk  8 [3,2, 3,3, 5,5, 2,2, 2,2, 2,1]
           , cat $ walk 11 [3,2, 2,2, 5,5, 2,2, 2,2, 2,3]
           ] )

using a helper function that builds a zig zag path

walk (8 :: Integer) [2,3,4,5]
-- ==> [8, 7,6, 7,8,9, 8,7,6,5, 6,7,8,9,10]

with possible implementation

walk x ws  = scanl (+) x
  $ concat $ zipWith replicate ws (cycle [-1, 1])

using functions https://hackage.haskell.org/package/base-4.21.0.0/docs/Data-List.html#v:scanl etc.

full code (it's not much longer) and rendered audio: https://git.imn.htwk-leipzig.de/waldmann/computer-mu/-/tree/master/tidal/code/ox?ref_type=heads

Next: any Baroque composer (Telemann, Handel, Corelli, ..) e.g., Sonatas for two recorders, by G. P. Telemann (1681–1767) this looks highly formulaic (= Kolmogorov-compressible in a pattern language) but is highly enjoyable, and the master of it all - is J S Bach, of course.

Thanks for that - very interesting, you reminded me to check it out and I decided I'm going to give it a try with existing tidal functions, there's a few that I'd like to understand a bit better which I think may be related. I also want to try and understand the relationship between scale use and note arithmetic better because I have some grey areas ... we'll see how far I get, there's a lot of patterns in that piece, but also a lot of pattern breaking...
