The tablature can be played from 'Standard G tuning' or G lowered to 'E tuning' (as John Hartford used to do)... Played in the key of cm... cm registers as am, however, in the lowered E tuning. All instrumental, although I included the lyrics for the intro... Moderately Challenging, depending on your skill level...
Supposedly, Pink Floyd had to hire a classical guitarist to play the guitar part of this tune as Pink Floyd did not have a fingerstyle-fluent guitarist (I found this out in the bio of the song in question on Wikipedia).
The arpeggiated chord progression with walking melody/bass works as well on the banjo as it does on the guitar.
Satisfying to the ears.
Fun to play...
