There are bad pedagogists (word - ? ) that use caged but the pattern, map, orientation, focal points, system - whatever you wanna call it - definitely exists (it can't not exist in standard tuning) and guitar players use it ... consciously or not. Now whether you (me as well) 'call' it that is another thing entirely. We (guitar players) play shapes and grips. It's the nature of our instrument. Some of us maybe have a lot more shapes and grips in our kit bag - ? It's just a 'nuts and bolts' thing. Musicality is of course the main objective. Just knowing the notes does not lead to tonal organization. For the record, I'd never even heard of caged until I found this forum. *I will also iterate that even though I know 'cold' where all my notes are and how to construct any scale and chord anywhere on the fretboard practically instantaneously - and I've known this for a long time, musicality as well as appropriate tonal organization can still be elusive ... regardless of my 'system'.
