Hi ,

What exaclty is this 2 thats added to a chord somethimes ? does it just mean play the barred shape ? ive found this with almost all the notes C, G, F etc.....and always tht C2 or Em2 was a different chord ....but recently i saw a few tabs were the designation for the chords was just the barred shape of the chords

Em2: 1 2 b3 5
Em: 1 b3 5

The '2' Indicates which interval to add to the minor chord.
In this case, you would add the second interval to E minor.

Example:
Em: E G B
Em2: E F# G B

Sometimes a tabber will say C2 to mean C barred and just C to mean an open chord. Same goes for an Em. Its just a way to distinguish the two in a song. If they mean an Em with an added 2, they would say Emsus 2, as then it would be a sustained chord.

Sus2 means that the 2nd or 9th replaces the the 3rd in the chord.
