Until we rid ourselves of the notion that the best music of all time was created by a handful of men who lived an ocean away from us and who all died more than a century before any of us were born, we will never have programming that truly reflects the vast array of musical creativity all around us.
Experienced musicians eventually arrive at a point where the physicality of the instruments they play seems to disappear. It’s at this point that proprioception, e.g. muscle memory, provides the player with a cognitive shortcut that frees the conscious mind from primarily focusing on the mechanical details of music performance and allows it to address issues of aesthetics.
There have been few additions to the canon of “classical” music from Africa, or most of southern Asia and Oceania. And yet, despite the efforts of extremists in various parts of the world, some form of music is created, performed, and listened to in every nation on the planet; music is one of the few pan-terrestrial human activities.
Scientific research shows that listening to music is an activity that fosters cohesion and synchronicity in brain function, which is very good for social messaging across large numbers of people who are listening at the same time, whether or not they’re listening to the same thing. I believe the research also shows that improvising music requires a similar mode of cognition, allowing for a kind of “disembodied cognition,” as one researcher calls it.
Charles Ives, George Gershwin, Leonard Bernstein, and John Corigliano have all used music to promote social commentary, but these are all individuals who use their talents to create great music and see it performed. To the Great American Culture Machine, music is still mainly seen as a pastime marketed primarily to sexually frustrated adolescents with enough money to buy new product.
