Take, for example, the compositions of Antonio Vivaldi, who is familiar to many listeners entirely on the basis of the first four concertos, called ``The Four Seasons,'' of his elaborate 12-part Opus 8. And this seems a bit of a shame, given the treasury of accessible and accomplished 17th-century music that is still largely unknown. But now, recording the golden oldies of the Baroque has faded from fashion. Almost at once a search began for other ``Great Hits of 1700.'' As a result, we now have a long list of recordings of lovely adagios and airs by various Baroque composers. This orchestral version of an organ piece by the little-known 17th-century German composer became a hit. Then, quite suddenly, recording after recording was released of Pachelbel's Canon in D.

A DECADE ago, audiophiles rarely encountered the music of an obscure Baroque composer by the name of Johann Pachelbel.
