Does the color of one’s skin have any bearing on the kind of music one writes? Should a black composer be expected to incorporate jazz or spiritual inflections into his or her music?

Tune in tomorrow morning to have lazy expectations confounded. We’ll have representatives of the jazzy and spiritual schools, of course, but we’ll also hear works by a Pulitzer Prize winner who makes his home in New Jersey, an Afro-Cuban master of the guitar, a musketeer in the service of Louis XVI, and an Englishman infatuated with the works of Henry Wadsworth Longfellow.

Clipper Erickson, piano of Westminster Conservatory of Music will drop by at around 10:00 to talk a bit about R. Nathaniel Dett, the grandson of fugitive slaves, who went on to become an important voice in American music. Erickson’s album of Dett’s complete piano works, “My Cup Runneth Over,” has recently been issued on the Navona Records label.

In addition, we’ll hear recordings of the late conductor Paul Freeman, some spirituals sung by Marian Anderson, and the cantata “Done Made My Vow” by Adolphus Hailstork, in a recording made by the Baltimore Symphony Orchestra.

In advance of MLK Day, it’s an exploration of content, character and color, with music by composers of African descent, tomorrow morning from 6 to 11 ET, on WPRB 103.3 FM or at wprb.com. Music is King, on Classic Ross Amico.
