# Words & Sounds

Word definitions let you abstract sound design into reusable units.

## Defining Sounds

```forth
: lead "saw" s 0.3 gain 1200 lpf ;
```

Use it with different notes:

```forth
c4 note lead .
e4 note lead .
```

## Self-Contained Words

Include the emit to make the word play directly:

```forth
: kk "kick" s 1 decay . ;
: hh "hihat" s 0.5 gain 0.5 decay . ;
```

Steps become simple:

```forth
kk
0.5 at hh
```

## Effect Presets

```forth
: dark 800 lpf 0.6 lpq ;
: wet 0.7 verb 8 verbdiff ;
```

```forth
c4 note saw s dark wet .
```
