This arrangement of Johan Pachelbel's famous melody is very challenging because it literally goes everywhere on the fretboard.
It is possible to edit it to a simpler form, but I decided to leave it as is.
It is also very possible on any chord, to play just the highest sounding three notes. That would be the first thing you could do to make it a little easier to play.
Other than that, besides length, number of chords and all over the neck, it's not all that bad!
