# Pattern Constructors

The following functions will return a pattern.
These are the equivalents used by the Mini Notation:

| function                       | mini             |
| ------------------------------ | ---------------- |
| `cat(x, y)`                    | `"<x y>"`        |
| `seq(x, y)`                    | `"x y"`          |
| `stack(x, y)`                  | `"x,y"`          |
| `timeCat([3,x],[2,y])`         | `"x@3 y@2"`      |
| `polymeter([a, b, c], [x, y])` | `"{a b c, x y}"` |
| `polymeterSteps(2, x, y, z)`   | `"{x y z}%2"`    |
| `silence`                      | `"~"`            |

## cat

<JsDoc client:idle name="cat" h={0} />

You can also use cat as a chained function like this:

<JsDoc client:idle name="Pattern.cat" h={0} hideDescription />

## seq

<JsDoc client:idle name="seq" h={0} />

Or as a chained function:

<JsDoc client:idle name="Pattern.seq" h={0} hideDescription />

## stack

<JsDoc client:idle name="stack" h={0} />

As a chained function:

<JsDoc client:idle name="Pattern.stack" h={0} hideDescription />

## timeCat

<JsDoc client:idle name="timeCat" h={0} />

## polymeter

<JsDoc client:idle name="polymeter" h={0} />

## polymeterSteps

<JsDoc client:idle name="polymeterSteps" h={0} />

## silence

<JsDoc client:idle name="silence" h={0} />

## run

<JsDoc client:idle name="run" h={0} punchcard />
