Mathematica 95 112 100 97 104 chars
Admittedly not very streamlined:
Take[Flatten@Table[# <> ToString@k & /@ Partition[Characters[" CDb DEb E FGb GAb ABb B"], 2], {k, 0, 8}], {10, 97}] The Flat symbol, although it occupies a single character, is transcribed to SO as \[Flat] so I used the letter "b" here.
Output:

Length@% (* out *) 88
