The tab reads

e|--0---------------|--------------------|-------------------|-----------------|
B|--1---------------|--2-----------------|--0----------------|-4---------------|
G|--0---------------|--0-----------------|--0----------------|-4---------------|
D|--2---------------|--2-----------------|--2----------------|-4---------------|
A|--3---------------|--1-----------------|--2----------------|-2---------------|
D|------------------|--------------------|-------------------|-----------------|

I understand that the last two are e minor and b major, but how about the first two? What kind of chords are those?!
#2
First one is a C chord? Literally one of the most common chords of all time. Frankly i'm shocked you know the last 2 and not that one.
As for the second..
My theory isn't too brilliant but i thought it was like.. an A7 chord with an A# on the root. It has the notes of an A7 pretty much (A, C#, E, G), so I'm just assuming the A# is for a little wacky flavour.I'm sure a more enlightened person will be able to answer that chord in particular.

... The first one is C major. You should know that without even having to think.

The second is a bit more unusual but it's an A# diminished.

There we go. While you're here by the way Zaphod, do you have any particular place to recommend going for learning up on the theory behind augmented and diminished chords? I should probably learn them already.

You can probably do some google research.

That second one is a Dim7, not Dim. It's functioning as a dominant chord leading to the tonic Em.

I't's also amazes me that you've never seen an open C chord.

Actually now that you mention it I do recognise the C major chord shape, I'm just not used to seeing it written as a tab.

I've checked and it is indeed Dim7, though I would have never have thought of looking for a 7th diminished if you've never figured it out. Thanks for the help.
