So referring to the image Buoy linked, it explains how mare flat/sharp keys of a certain note are there, over varying octaves then?
It tells you how many flats or sharps there are for each scale/key (per octave).
Btw when I say key I mean scale, not an individual key on an instrument. (Confusing? Yeah.)
Now modulation's something else that I don't get. How does it work/What the purpose of it?
Modulating can have many different meanings in music. It depends on the context. Generally it means to change pitch (to transpose). Like if a song is written in E flat, it's based around the E flat scale/key. If you want to play it in D, you need to shift each note halve a tone down.
You can also modulate within a song. In some cheesy pop-songs they repeat the chorus, but they transpose it a few tones upwards. This is for an uplifting effect or something.
On key instruments there often is a modulation wheel. This is to add vibrato, and has nothing to do with the aforementioned definitions.
I think there are more meanings of the word modulation, but those are less common and I don't know all of them.
