Slash Notation
The first letter is the root. If major then B, if minor then Bm, if augmented then B+, if diminished then Bo. If the chord is not in root position, then the letter of the bass note is written, and then a slash and next to it the letter of the original root. For example, if there is a chord built of C#, A, and E, then the slash notation would be A/C#.
