"Feeling" is the unteachable aspect of guitar playing. If two people took the same music courses in college, it's the quality that makes them different as musicians. Over an A Minor chord, one would perhaps play, C, B, A, E, whereas the other might play B, A, G, E.

Your "feeling" cannot be taught to you because it's yours. If someone taught you feeling, then you wouldn't have feeling, you'd be a copy.

Play and play and play and play some more over chord progressions. Your inner ear will tell you what's good and what's not. This is your "feeling". You're not playing other people's notes, but the ones that YOU like.
