Arnold Schoenberg's 2 tone music

Oh dear, the spell is broken!

Radio 4's often spellbinding Something Understood was talking about 'desire lines' this morning and its most regular presenter, Mark Tully - the ultimate in BBC authoritative voices - played us a waltz by Arnold Schoenberg.

As the music played, the infallible voice of Mark Tully re-entered, saying:

Oh, not even to be able to believe in the infallibility of Mark Tully and Something Understood any more! The BBC is truly lost.

For those who aren't up on music, this is what Schoenberg's waltz sounds like:

And this is what two tone music sounds like:

Mark Tully meant twelve tone music,

My faith in the BBC will never recover from this.
