As for Pachelbel's Canon In D, it was for a chamber orchestra originally, wasn't it?
At any rate, this issue came up some weeks ago in one of the piano forums. Where is the TRUE version of the Canon in D? Actually, when the Canon is written for solo piano, it is a transcription and there is no standard.
I have sort of collected them, and have about 5 transcriptions. Some are not even in the key of D. One is in G, and one is in C.
They are in varied levels of difficulty.
One of them, that I most detest, is really variations on the Canon in D. No trace of the original melodic line exists. The composer just uses the chord progression as a "trip" to do his own thing.
The George Winston version appears to be thought of as quite excellent, but I -- alas-- don't have this particular version.
Lots of luck. Good question --
