We can play more notes by separating them with spaces:
|
||||
|
||||
<MiniRepl client:idle tune={`note("c e g").punchcard()`} drawTime={[0, 4]} />
|
||||
<MiniRepl client:idle tune={`note("c e g b")`} punchcard />
|
||||
|
||||
Here, those four notes are squashed into one cycle, so each note is a quarter second long.
|
||||
Try adding or removing notes and notice how the tempo changes!
|
||||
|
||||
<MiniRepl client:idle tune={`note("c d e f g a b").punchcard()`} drawTime={[0, 4]} />
|
||||
<MiniRepl client:idle tune={`note("c d e f g a b")`} punchcard />
|
||||
|
||||
Note that the overall duration of time does not change, and instead each note length descreases.
|
||||
This is a key idea, as it illustrates the 'Cycle' in TidalCycles!

We can slow the sequence down by enclosing it in brackets and dividing it by a number (`/2`):
|
||||
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/2")`} />
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/2")`} punchcard />
|
||||
|
||||
The division by two means that the sequence will be played over the course of two cycles.
|
||||
You can also use decimal numbers for any tempo you like (`/2.75`).
|
||||
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/2.75")`} />
|

<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/2.75")`} punchcard />

## Angle Brackets
|
||||
|
||||
Using angle brackets `<>`, we can define the sequence length based on the number of events:
|
||||
|
||||
<MiniRepl client:idle tune={`note("<e5 b4 d5 c5>")`} />
|
||||
<MiniRepl client:idle tune={`note("<e5 b4 d5 c5>")`} punchcard />
|
||||
|
||||
The above snippet is the same as:
|
||||
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/4")`} />
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]/4")`} punchcard />
|
||||
|
||||
The advantage of the angle brackets, is that we can add more events without needing to change the number at the end.
|
||||
|
||||
<MiniRepl client:idle tune={`note("<e5 b4 d5 c5 e5>")`} />

This is more similar to traditional music sequencers and piano rolls, where adding a note increases the perceived overall duration.

Contrary to division, a sequence can be sped up by multiplying it by a number using the asterisk symbol (`*`):
|
||||
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]*2")`} />
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]*2")`} punchcard />
|
||||
|
||||
The multiplication by two here means that the sequence will play twice a cycle.
|
||||
|
||||
As with divisions, multiplications can be decimal (`*2.75`):
|
||||
|
||||
<MiniRepl client:idle tune={`note("[e5 b4 d5 c5]*2.75")`} />

## Elongation

With the "@" symbol, we can specify temporal "weight" of a sequence child:

This algorithm can be found in many different types of music software, and is often referred to as a [Euclidean rhythm](https://en.wikipedia.org/wiki/Euclidean_rhythm) sequencer, after computer scientist Godfriend Toussaint.
|
||||
Why is it interesting? Well, consider the following simple example:
|
||||
|
||||
<MiniRepl client:idle tune={`s("bd(3,8,0)")`} />
|
||||
<MiniRepl client:idle tune={`s("bd(3,8,0)")`} punchcard canvasHeight={50} />
|
||||
|
||||
Sound familiar?
|
||||
This is a popular Euclidian rhythm going by various names, such as "Pop Clave".
|
||||
These rhythms can be found in all musical cultures, and the Euclidian rhythm algorithm allows us to express them extremely easily.
|
||||
Writing this rhythm out in full require describing:
|
||||
|
||||
<MiniRepl client:idle tune={`s("bd ~ ~ bd ~ ~ bd ~")`} />
|
||||
<MiniRepl client:idle tune={`s("bd ~ ~ bd ~ ~ bd ~")`} punchcard canvasHeight={50} />
|
||||
|
||||
But using the Euclidian rhythm notation, we only need to express "3 beats over 8 segments, starting on position 1".
|
||||
|
||||
This makes it easy to write patterns with interesting rhythmic structures and variations that still sound familiar:
|
||||
|
||||
<MiniRepl client:idle tune={`note("e5(2,8) b4(3,8) d5(2,8) c5(3,8)").slow(4)`} />
|
||||
<MiniRepl client:idle tune={`note("e5(2,8) b4(3,8) d5(2,8) c5(3,8)").slow(4)`} punchcard canvasHeight={50} />
|
||||
|
||||
Note that since the example above does not use the third `offset` parameter, it can be written simply as `"(3,8)"`.

|

`beats`: the first parameter controls how may beats will be played.

|

<MiniRepl client:idle tune={`s("bd(2,8)")`} />
|

|
||||
|
||||
### Segments
|
||||
|
||||
`segments`: the second parameter controls the total amount of segments the beats will be distributed over:
|
||||
|
||||
<MiniRepl client:idle tune={`s("bd(3,4)")`} />
|
||||
<MiniRepl client:idle tune={`s("bd(3,8)")`} />

|
||||
<MiniRepl client:idle tune={`s("bd(3,13)")`} punchcard canvasHeight={50} />
|
||||
|
||||
### Offsets
|
||||
|
||||
`offset`: the third (optional) parameter controls the starting position for distributing the beats.
|
||||
We need a secondary rhythm to hear the difference:
|
||||
|
||||
<MiniRepl client:idle tune={`s("bd(3,8,0), hh cp")`} />
|

<MiniRepl client:idle tune={`s("bd(3,8,3), hh cp")`} />
