A, E, G, and D... you're just playing the open strings

Seriously, you can't tell what key you're playing in from that. It could be a number of keys. More info please? What is the whole bass line? Have you got any chords? A recording of you playing it?

Heh, don't worry, no need to feel stupid

Now, when you say the chords are A E G and D, I'd assume you mean A Major, E major, G Major and D Major.

In which case, I'm gonna go with A Major as the key, here. G being the non-diatonic chord.

More specifically, you're playing "Scooby Snacks" by Fun Lovin' Criminals

As for the 'why' part...

Well, the first chord is A, which is the first hint. The second chord is E, which is the dominant in the key of A. So far, this seems to suggest A Major, because these are the two strongest and most common chords in any key - chords I and V (1 and 5). Starting on I and moving to V is a very common thing to do. Ok, the next chord is G. Now this isn't diatonic to the key of A Major (i.e. it contains notes not in the A Major scale - specifically, the G. The A Major scale contains a G# not a G). But that's ok, it doesn't necessarily stop it being in A. The last chord is D - which is diatonic to A Major, and is another very common chord in any key - chord IV (chord 4).

So, what we've got here is a chord sequence which contains three chords belonging to A Major (the A, E and D chords), and one chord that doesn't (the G chord). In fact, there isn't one key, in which all these chords are diatonic. But, it starts on A, and moves to E - a very strong start to an A Major progression. It then moves out of key, for the G Major chord, and then brings it back round with the D Major chord.

So yeah, I'm going with A Major.

Generally speaking, the first and last chord (most often they are the same) will identify the key of the song.
