It's a simple goal, really.

There are tons of excellent guitar players who play efficiently, melodically and with great innovation when it comes to using the whole neck of the guitar. Not all of them know what notes they are playing.

But I want to go from looking at the neck of my guitars as decreasingly wide spaces punctuated here and there with birds to seeing, no, knowing every fretted note.

I'm on a campaign now to know my neck.

Have you done it? Was it a conscious effort or did it just happen over time? Did you set out to learn it as a goal with exercises or did you just one day realize that you weren't thinking about where the G#s is are the fourth string?
