I have recently discovered Just A Minute radio on the Tune-In Radio app. Continuous relay of nearly 50 years of this amusing BBC panel game is offered.Each programme is introduced with Chopin’s so-called Minute Waltz. The waltz is in  D flat major. I have enjoyed getting my fingers round the notes over the years. A party trick is to let the right hand get well ahead of the rhythmic left hand.

Listening to these programmes I have been pleased to note that Chopin’s waltz is in D flat as consistently as Nicholas Parsons is in the chair. I hope that it is so deeply embedded in my auditory DNA after over 40 years of listening to Just A Minute and playing the music myself that it wll never shift.
