+- We have a word `freq` which is followed by some brackets `()` with some words/letters/numbers inside, surrounded by quotes `"220 275 330 440"` (corresponding to the pitches a3, c#4, e4, a4).
 - Then we have a dot `.` followed by another similar piece of code `s("sine")`.
 - We can also see these texts are _highlighted_ using colours: word `freq` is purple, the brackets `()` are grey, and the content inside the `""` are green.
