I'm looking to take several steps backwards. Rather than learn Emil's more advanced arrangements, I want to learn dozens of melodies/songs and have a process of arranging with different feels. Also be able to take them in all keys and all over the neck.

Ex. Take the melody of a pop song. Play it with just bass lines, then add to the bass, add rhythm ect. I can learn melodies and chords by ear it just struggle to arrange it into something.

Any advice on how to approach this or course recommendations? Teachers?

Thanks,
Brock
