Here’s another version that introduces much more variety of texture, longer than the previous ones due to more long measures chosen than other versions. The pre-processor chooses which measure length from the following code:
.pick-len-s32 &chor-x*.&all-32-a*. &vel.d32&w-pick-len32.
.pick-len-s48 &chor-x*.&all-48-a*. &vel.d48&w-pick-len48.
.pick-len-m64 &chor-x*.&all-64-a*. &vel.d64&w-pick-len64.
.pick-len-m96 &chor-x*.&all-96-a*. &vel.d96&w-pick-len96.
.pick-len-l128 &chor-x*.&all-128-a*. &vel.d128&w-pick-len128.
.pick-len-l192 &chor-x*.&all-192-a*. &vel.d192&w-pick-len192.
.pick-len-l256 &chor-x*.&all-256-a*. &vel.d256&w-pick-len256.
.pick-len-l384 &chor-x*.&all-384-a*. &vel.d384&w-pick-len384.
.pick-len-x512 &chor-x*.&all-512-a*. &vel.d512&w-pick-len512.
.pick-len-x768 &chor-x*.&all-768-a*. &vel.d768&w-pick-len768.
The 32 beat measures are short, and the 768 beat measures are 24 times longer, so if more longer ones are picked, the piece will last a longer time. The &chor-x*. variable chooses the key. &w-pick-lenxx. writes out to a log file the choices.
Here’s what it picked this time:
pick-len-256
pick-len-192
pick-len-256
pick-len-192
pick-len-32
pick-len-32
pick-len-32
pick-len-32
pick-len-128
pick-len-768
pick-len-32
pick-len-768
pick-len-192
pick-len-128
pick-len-96
pick-len-128
pick-len-32
pick-len-32
pick-len-32
pick-len-32
pick-len-192
pick-len-768
pick-len-512
pick-len-768
pick-len-384
pick-len-256
pick-len-384
pick-len-512
Lots of those long 768 beat measures and not so many 32 and other short measures.
On top of the Markov Chain process, there’s the chance that a note will be silent regardless of all the chains at work. In this version, the odds are as much as 68.5% that a note will sound, to as low as 31%. That leaves a more sparse landscape for much of the piece. The keys are at the edges of the list of available keys, and wrap-arounds make the changes more strange than usual.
The list of potential keys:
Cn-Maj
Ab-Maj
Fn-Maj
D+-Maj
A+-Maj
F+-Maj
E--Maj
Db-Maj
Fn-Min
A--Min
Cn-Min
D+-Min
Gn-Min
B--Min
Db-Min
Eb-Min
The choices this time:
E--maj
Db-maj
Fn-min
Db-maj
E--maj
Db-maj
Fn-min
A--min
Cn-min
D+-min
Cn-min
A--min
Fn-min
Db-maj
Fn-min
Db-maj
E--maj
Cn-min
F+-maj
A+-maj
D+-maj
Fn-maj
D+-maj
A+-maj
D+-maj
Fn-maj
D+-maj
A+-maj
D+-maj
Fn-maj
The bulk of the time it’s in Db Major, and E- Major. All at the far reaches of the diamond.
I should mention that Castilleja miniata is the latin name for the common paintbrush, responsible in part for the proliferation of colors on the mountains up here.
