+Pull requests welcome! Consider starting with discussion or proof-of-concept first, rather than do loads of work on something and then find it doesn't fit the collective goals of the project, or something like that.

+
+Strudel is a project handmade by humans, with thought and nuance. 
+
+If you have used LLMs (so called 'AI'), please detail that in the pull request. We are still developing our response to the onslaught of LLM technology, but for practical and legal reasons are currently not accepting wholly LLM-generated code. We are also not accepting PRs that add LLM features to strudel itself.

+There are #llm-chat and #llm-share channels on our discord. Please do not discuss or share LLM-related things outside of those channels.

 ## Report a Bug

 ### Additive Synthesis

-To tame the harsh sound of the basic waveforms, we can set the `n` control to limit the overtones of the waveform:
+Periodic waveforms are composed of several [harmonics](https://en.wikipedia.org/wiki/Harmonic) above a fundamental frequency, lying at integer multiples. These overtones combine to give a sound its unique timbral quality.
+
+For the basic waveforms, we offer you control over these harmonics with the `partials` and `phases` functions.
+
+#### Partials
+
+`partials` refers to the magnitude of each harmonic relative to the fundamental frequency. They can thus be used to spectrally filter these waveforms and tame some of their harshness:

 <MiniRepl
  client:idle
  tune={`note("c2 <eb2 <g2 g1>>".fast(2))
 .sound("sawtooth")
-.n("<32 16 8 4>")
+.partials([1, 1, "<1 0>", "<1 0>", "<1 0>", "<1 0>", "<1 0>"])
 ._scope()`}
 />

-When the `n` control is used on a basic waveform, it defines the number of harmonic partials the sound is getting.
-You can also set `n` directly in mini notation with `sound`:
+`partials` can also be used to construct _new_ waveforms not present in our basic set with the 'user' sound source:

 <MiniRepl
  client:idle
  tune={`note("c2 <eb2 <g2 g1>>".fast(2))
-.sound("sawtooth:<32 16 8 4>")
+.sound("user")
+.partials([1, 0, 0.3, 0, 0.1, 0, 0, 0.3])
 ._scope()`}
 />

-Note for tidal users: `n` in tidal is synonymous to `note` for synths only.
-In strudel, this is not the case, where `n` will always change timbre, be it though different samples or different waveforms.
+We may algorithmically construct lists of magnitudes with Javascript code like:
+
+<MiniRepl
+  client:idle
+  tune={`const numHarmonics = 22;
+note("c2 <eb2 <g2 g1>>".fast(2))
+.sound("saw")
+.partials(new Array(numHarmonics).fill(1))
+._scope()`}
+/>
+
+which acts as a spectral filter. Or:
+
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>").fast(2)
+.sound("user")
+.partials(new Array(50).fill(0)
+  .map((_, idx) => ((-1) ** (idx + 1)) / (idx + 1))
+)
+._scope()`}
+/>
+
+which recovers a familiar waveform.
+
+`partials` is also compatible with pattern functions designed to produce lists, like `randL` or `binaryL`:
+
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>").fast(2)
+.sound("user")
+.partials(randL(10))
+._scope()`}
+/>
+
+and with lists _of_ patterns:
+
+<MiniRepl
+  client:idle
+  tune={`note("c2 <eb2 <g2 g1>>".fast(4))
+.sound("user")
+.partials([1, 0, "0 1", "0 1 0.3", rand])
+._scope()`}
+/>
+
+Note that the first value in the `partials` array controls the magnitude of the fundamental harmonic rather than the DC offset, which is fixed at 0.
+
+#### Phases
+
+Earlier, we mentioned that periodic waveforms can be broken into a set of harmonics above a fundamental frequency. Each harmonic has two defining properties: its magnitude (how loud it is) and its phase, which determines where in its cycle that sine wave starts when the waveform is built.
+
+These phases too can be declared in Strudel and can give your sounds interesting depth.
+
+<MiniRepl
+  client:idle
+  tune={`s("saw").seg(16).n(irand(12)).scale("F1:minor")
+  .penv(48).panchor(0).pdec(0.05)
+  .delay(0.25).room(0.25)
+  .compressor(-20).vib(0.3)
+  .partials(randL(200))
+  .phases(randL(200))`}
