One shouldn't, of course, anchor a general claim on a single phenomenon - but, yes, Alan, I agree with you fully. Sadly, the BBC can't be said to much progress our musical knowledge (or shake us out of complacency): it rather reflects what is fashionable and thereby, I suppose, pats itself on the back for delivering what the public wants. And that is surely not what the BBC should be doing.
And that great Suk masterpiece is an apt case in point. It was composed in 1905 (I believe, without having checked!), but then didn't really emerge into the English musical consciousness until about the early 1980s. And as far as I recall it wasn't the BBC that pushed into that status, but a series of distinguished recordings that have continued ever since (several are on my shelves, and each one is a stunner). So three cheers for the private record companies and nil praise for the BBC here.
But I'm going to stay on the lower slopes and not climb up higher and attempt an explanation of its reception from the 1980s onwards. But - and I don't intend to be trivial - the following comes to mind. First, 'Suk' unlike e.g. 'Stojowski' is an easy name to drop (and to spell); second, the symphony has a title (and cf the named symphonies of Haydn are, for good or ill, more memorable than 'Symphony No. 7 in E flat major'); third, and most important here, the work is always associated with the biographical circumstances of its composition and as, Schopenhauer pointed out, it is the dreadful and the tragic that fully impress themselves on the human mind and not the happy or joyful. In other words the PR departments of record companies have had a fairly easy time in selling records of the Asrael Symphony. I've never seen liner notes accompanying recordings of the work that don't tell us about the deaths of those close to Suk. And Mr Public thrives on it. Would the Symphony have achieved its present status had these three factors not been the case? I somehow doubt it, and the work would have continued its pre-1980 status and the BBC would have received a few postings from the enlightened pleading for a broadcast.
So Aunty Beeb has received quite a pasting in this thread. Anyone like to defend it?
