# Strudel Code
Now that we have played some notes using different sounds, let's take a step back and look how we actually achieved this using _code_.

Generally, `xxx` and `yyy` are called [_functions_](https://en.wikipedia.org/wiki/Function_(computer_programming)), while `foo` and `bar` are called function [_arguments_ or _parameters_](https://en.wikipedia.org/wiki/Parameter_(computer_programming)).

So far, we've used the functions to declare which aspect of the sound we want to control, and their arguments for the actual data.
The `yyy` function is called a [_chained_ function](https://en.wikipedia.org/wiki/Method_chaining), because it is appended with a dot (`.`).

# Comments
The `//` in the example above is a line comment, resulting in the `delay` function being ignored.
It is a handy way to quickly turn code on and off.
It is a handy way to quickly turn code on and off.
Try uncommenting this line by deleting `//` and refreshing the pattern.
You can also use the keyboard shortcut `cmd-/` to toggle comments on and off.
# Strings
Ok, so what about the content inside the quotes (e.g. `"a3 c#4 e4 a4"`)?
In JavaScript, as in most programming languages, this content is referred to as being a [_string_](https://en.wikipedia.org/wiki/String_(computer_science)).

A string is simply a sequence of individual characters.
In TidalCycles, strings are used to write _patterns_ using the mini-notation, and you may hear the phrase _pattern string_ from time to time.
