I like playing the piano by following guitar chords. However I don't understand, and nor can I find any reference material, on what certain chords mean.
Here's the example (click below to view - the rest of this question will make more sense if you do! :-)):
Trail We Blaze - Chords
I understand most of these chords (or "tabs"). For example:
E = E major = E + G# + B
A/E = A major using E as root note = E + A + C#
B6 = B major 6th = B + D# + F# + G#
But there are a few I don't understand. Your help please :-)
C# no 3rd add 4th.
I am GUESSING this means C + E + G. (no 3rd = no D#, add 4th = E). But then why not just write C?
F# Natural. I am guessing this is F# + A# + C#. But then why is "nat" needed, surely it is natural by default unless there are qualifiers added?
G/A. This is the most confusing of all. There is no "A" in the G major chord. How can A be the root note if it doesn't even exist in the chord of G?
Em4th. I'm not familiar with 4ths as I am with 7ths. It would be great if someone could explain what this is and why.
Thanks so much - and I'd appreciate if you give the actual notes and the reason why those notes are the ones!
