In which I find out I really can't say the word "mininotation"..
This video is a few things lumped together - a run through the tasks on the last worksheet, how to upgrade tidal, and finally how to use the "Euclidean notation". Use the links below to jump to a particular part.
0:00 - hello
0:27 - run through the tasks from the previous video
8:47 - how to upgrade Tidal
10:34 - how to check the tidal version you're on with tidal_version
10:50 - Euclidean notation - making all the rhythms with just two numbers
In brief:
Upgrade Tidal by opening a terminal window and running
cabal update
cabal install tidal --lib
If you're on an older version of haskell, you might have to remove the --lib and just run cabal install tidal.
If you're on a mac and get 'command not found' or similar, you might have to run . ~/.ghcup/env before the above.
The main difference is the addition of the draw function, which I use in the video to explore what the euclidean syntax is doing. There's also drawLine which I forgot to show in the video - it's actually clearer as it shows multiple cycles.. e.g.:
drawLine $ "[x [a c b]/2 x x, a x [c d]]"
draws:
[6 cycles]
|x--a-c---x--|x-- b-x--x--|x--a-c---x--|x-- b-x--x--|x--a-c---x--|x-- b-x--x--
|a---x---c-d-|a---x---c-d-|a---x---c-d-|a---x---c-d-|a---x---c-d-|a---x---c-d-
I'll paste the list of example Euclidean structures below. So for the Persian rhythm "Khafif-e-ramal"
d1 $ sound "clap(3,5,2)"
It's useful to have a kick or something at the start of each cycle as a reference point:
d1 $ sound "kick:5"
