The Monkees had the good fortune to get songs from great songwriters. Daydream Believer was written by John Stewart, who had spent the previous years with The Kingston Trio.
The Monkees’ arrangement was quite different, even as far as the chord progression, but really captured, and even amplified the ‘feel good’ nature of the song.
Their version is in the key of G and the main accompaniment was done on keyboards. This lesson is done in G but uses Dropped D Tuning to keep the relationship of the bass notes faithful.
