i posted a thread before bout tabs for beginners

but i just hav a questions bout tabs
this is probably gunna sound dumb but w/e:

Are tabs, songs, and riff the same thing?
Tab = modern form of writing down guitar parts.. E|-0-2-0-2-5-2-0-2- as an example.

Song = Exactly what it says on the box^^

Riff=Tiny part of a song. (sort of)

So, no, not really the same thing :3
