Bach was renowned for his improvisations on the organ, and organists today still continue the tradition that has become attenuated in other branches of WAM (see Unpacking “improvisation”). So in an invigorating Sunday-morning Prom (on BBC i-Player until the end of August), Martin Baker alternated his own improvisations on organ works by Bach with the original pieces—which presumably had a life as improvisations before he committed them to paper.
Of course, whereas Bach himself improvised in the tradition of his time (in the style of… Bach!), today’s organists improvising on his music have the whole diverse soundscape since then as their palette, though Baker opted for a relatively traditional language (indeed, some modern players like Robert Levin on fortepiano even improvise in the style of Mozart). Baker ended with a stimulating improvisation on English melodies familiar to the Prommers.
Here he is with an earlier, um, medley on Bach themes:
He was standing in for Oliver Latry, for whose remarkable performances *do* refer to my post on French organ improvisation—which also includes his elaboration on the B-A-C-H motif, as well as a film of Messiaen himself at the age of 76 playing three resplendent improvisations!!!
It all goes to show that
