What is the Midle ground to learn scales, chords and Arpeggios????
Yo play like a pro you need as much as those as possible but what do you think is the Midle ground for all knowledge and technique??
Afterall if you font play any song you don't really play any thing do you???
Cheers.

Honestly, just my personal opinion, I don't think there is a middle ground. It's all about translating what you hear in your head to the guitar and into music. Whatever it takes to learn and do that is what you need to do.
