Re: 20/20 Lennon Specal Last Night

The Beatles knew chords, they knew voicing, they learned 3-part harmony,
which is counterpoint.
Learning notation, per se, might have inhibited their style of creating,
which is through playing first.  Or, they might even have been fibbing
about not 'reading' music, as part of the myth that they were untrained
musicians...when they were, in fact, quite sophisticated...you see them
flipping from major to minor chords, using tritone substitutions,
rethinking old progressions...savvy stuff...
