“Silent Night” begins with the notes G A G E. “Lo, How a Rose E’er Blooming” starts with the same pitches, G G G A G G E. Arnold Schoenberg was delighted by this coincidence, and in 1921 wrote a little work for piano, string trio, and harmonium, in which one tune morphs into the other. Called Weihnachtsmusik, it’s absolutely charming – and not one new-music fan in thirty that I talk to has ever heard of it. In fact, it’s the one Schoenberg piece about which I feel most affectionate, and I almost have to assume that Schoenberg’s fans hide it because they’re ashamed that he wrote something so damn lovely. I’m adding it to Postclassic Radio, but I also put it here on my website, as a Christmas gift to you for reading me. The recording is an old Decca vinyl record by David Atherton and the London Sinfonietta, and I’ve never seen another. It was well after this, by the way, that Schoenberg asserted, “There’s a lot of great music left to be written in C Major.”
