I feel just like Bernard! I am pretty sure I have heard it before, but totally forgotten what it is! I am however almost certain that it is not Chopin. Instead of a "twiddle" I remember it as the first note being a dotted quarter-note (in 3/4 rhythm). I agree the last three notes are wrong. It is a piano piece allright, and if I remember correctly there is also an unobtrusive accompaniment of strings?

If I *really* rack my brain, I seem to remember that there is a woman's name in the title, and the composer just might be English. I could be totally wrong on the last two counts though.

It comes up fairly often on the radio stations that play light classical music.
