Chord Terminology
What is a chord?
What does 1 chord, 5 chord and so on mean?
The number represents the note in the scale - so a "1 chord" in C-Major simply means the C-Major chord. The "5 chord" would be G-Major.
What does add 9, add 11 mean?
What does sustained mean?
A "sus" chord is a chord with the middle note (todo: proper name here) moved up or down one step. So, sus2 is down, and a sus4 is up.
What does augmented mean?
Augment is to make larger - thats a good way to remember this one.
