"D" Novice/Beginner You play a repertoire chosen to be within your technical limitations. On a first reading, you usually aim to get through the music and end together without too many stops and starts in between.

"C" Fair You are in the process of exploring the standard repertoire, perhaps avoiding those works that are currently too technically challenging. You concentrate on not making major mistakes while reading an unfamiliar part, though you are aware of what the others are doing. You often slow down a fast movement for technical reasons.

"B" Good You are quite familiar with portions of the standard repertoire (perhaps pieces from certain periods or for certain instrumental/vocal combinations). You generally sound good and sight-reading is not a problem. You usually pay attention to blend, balance, dynamics, and basic phrasing on a first reading.

"A" Excellent You have extensive experience with and a strong command of the standard repertoire, from many time periods and for a variety of ensembles that include your instrument or voice. If your partners make a mistake, you can often bring them back in without stopping. You are a superior sight-reader and you consistently sound good (both in tune and at tempo). You already aim for cohesive musical expressiveness with attention to fine nuance on a first reading.

"Pro" Professional Musician You perform professionally.
