A Suspended 2nd
Asus2 is made of 3 notes: A, B and E. Here it is in root position, with A at the bottom.
Inside Notley Piano: all the inversions of Asus2, fingering for both hands, a play button, and practice that helps you remember it.
| Note | Degree | Interval from A |
|---|---|---|
| A | 1 | root |
| B | 2 | major 2nd |
| E | 5 | perfect 5th |
A sus2 chord replaces the 3rd with a major 2nd. With no 3rd it sounds open and airy, neither happy nor sad, and it often moves back to a major or minor chord.
