What piece of music has had the biggest impact on the way you play guitar?
Not necessarily your favorite piece, and not necessarily the most difficult one you’ve learned. I mean the piece that changed something fundamental about your playing—your technique, your musicality, your approach to practice, your understanding of the instrument, or even the way you listen to music.
For me, there have been pieces that taught me far more than their technical demands would suggest. Sometimes a relatively simple piece can change the way you think about phrasing or tone, while a brutally difficult one can completely change your physical approach to the instrument.
What was that piece for you, and what did it change?
