Sum of All Parts is an ABC Radio podcast here in Australia.
The podcast episode is called ‘The Magical Mystery Chord’.
Using the research and insights of mathematician and Beatle fan Professor Jason I. Brown, and personal experiences at Abbey Road Studios by Canadian musician Randy Bachman, the podcast un-picks just how The Beatles (with producer George Martin) achieved a chord that has tantalised musicians now for over fifty years…..
There is also a very short Sum of All Parts “bonus” episode, ‘Slow Down, George Solo-son’. Also well worth a listen.
