If you’re a serious student of guitar (like me) you might consider playing extemporaneously over a backing track as part of you practice regimen. It doesn’t have to be complicated- the best ones to get started with are simple, like a 1/4/5 change you can run your blues riffs over. Don’t forget to experiment with your phrasing, voicing and texture. “Texture” in music refers to how melodic, harmonic, and rhythmic elements combine and interact, creating the “feel” or density of the sound, like layers in fabric, described as thin/thick, light/heavy, or sparse/dense. In practical terms, that might mean playing more than one note at a time, bending a note while holding another one, or finding the note you want an octave above or below your current position. Really though, the list of things you can do to add texture to your playing is endless.
