This kind of thing was almost non-existent in the days when CDs and vinyl records were synonymous with the music business. Back in the old days helping people to play the compositions for themselves was limited to helping aspiring guitar heroes to learn the guitar solos, or aspiring stars to emulate current stars. The stuff you learned was by a larger-than-life player, and you learned in order to become larger than life yourself. It was about career in the sense that a successful learner was one who established a musical career.
For performers to encourage avocational musicians to learn to play the music for themselves is a sea change in publishing. It reflects the move to a participatory and inclusive concept where it’s expected and even intended that covers will show up on YouTube.
Exploring this space is the reason why I created sheet music, guitar tablature, and MIDI for Kristen Hirsh’s song “Elizabeth June.”
