I was stuck in a practice rut where I was kind of playing the same uninspired thing every time I picked up my guitar. I noticed I was always gravitating to the 5th fret A barre chord whenever I picked up my guitar. I seemed to be stuck strumming the A (I), D (IV), E (V) barre chords over and over. I think part of it was that I was coming to my practices already tired from work and not really feeling up to diving into some complicated song passage. I just wanted to strum. Anyway, so I decided that was okay for having a low energy, unfocused strumming screw-around. However, I figured if I was just going to strum some barre chords, I should probably get off the 5th fret and move around the neck a little. I decided I would strum I, IV, V chords in strumming patterns and chucks that I liked playing. To keep my fretboard memorization going, I decided to say the chord name every time I changed to the new chord. I also threw in the condition that I couldn't move to a new chord until I had its name in my mind. So I started down the fretboard playing the barre chords on the natural notes along the sixth string. Those were my I chords. I'd drop down to the 5th string and play the IV chord, then jump two frets and play the V chord, and then head back to the I chord or noodle around however I wanted. Anyway, this became something of a warm up for me. Chords F-Bb-C (Begin on 1st fret) G-C-D (3rd fret) A-D-E (5th fret) B-E-F# (7th fret) C-F-G (8th fret) D-G-A (10th fret) E-A-B (12th fret) . . . So I played around with this for a couple of days as a warmup. Anyway, so I come to TDPRI and start listening to tunes people link to. The first song I listen to I immediately recognize it starting on the 10th fret D chord. I picked up my guitar strummed along with the song. Yep, it was the 10th fret D chord. Anyway, the upshot of all this is that this little exercise really opened my ear up. It seems so obvious to me now that this would expand my musical consciousness. I wish I had tried it 10 years ago when I first learned barre chords.
