Sorry if this was a double post. I want to take several steps back with fingerstyle guitar. I want to take dozens of simple melodies/songs (like nursery rhymes) and arrange them in all keys. So when I hear a new melody I have a few ways of arranging on the spot. For now I just want to take these simple melodies and play them with chords in a handful of different styles (just root 3rd and 5th for now). Is there a resource that teaches this? Something like take mary had a little lamb and do it boom chick style, then just bass notes with the melody, then maybe arpeggios in the bass line with the melody ect.
