Mr. Blue Sky is a feel-good song for the ages. It’s highly orchestrated and is often called “Beatlesque”. This transcription of the song has several different parts transcribed for the guitar including the vocal melody, piano, bass, strings, calliope (a type of steam organ), synth, and lead guitar.
It’s a lot of fun to learn and play through different parts. It’s educational too because you get to play through things that you normally wouldn’t play on the guitar such as the piano part. Playing parts created by different instruments can be a big eye-opener because each instrument has a different approach.
