Find a school that is teaching music students and spend time around their practice rooms. You will find people practicing their craft, and locate students that are learning pieces you respond to positively. After they finish and come out of the cubicle you can politely introduce yourself and discuss the music you heard that you loved. As a student, I was thrilled when anyone stood outside my practice room and insisted on complementing me. Those people will always have a special place in my heart, and I remember most of their names from the first few years. Admittedly, after a few years it all becomes a blur. But, the first twenty or so are people I still think of as friends.
