* Music Hath the Soul to . . . Note: The top tune last week in South Africa was Paul McCartney's paean to racial harmony, "Ebony and Ivory," according to the British music publication New Musical Express . . .

* Ars Longa, Vita Brevis Note: Rainer Werner Fassbinder, the German filmmaker who died last month at the age of 36, worked fast and often. At the time of his death he had three films in the can. One of them, "Lola," will be opening in New York later this week. The film is the second in a trilogy depicting postwar Germany that began with "The Marriage of Maria Braun."

* Stars for Stars Note: When "Mass Appeal" ran last season on Broadway it garnered good reviews and Tony nominations but not enough, well, mass appeal at the box office. Now a production has surfaced in Aspen, Colo., with Charles Durning and John Travolta . . . and is rumored for a tour of the West Coast.

* No Taxation Without Representation (in the audience) Note: As the audience, some of whom had paid $142 for a ticket, gathered last Monday at the Salzburg Music Festival to hear Loren Maazel conduct Beethoven's opera "Fidelio," they were greeted by a chorus of jeers. One hundred Austrian demonstrators had gathered to protest the use of public money for the festival, which they claimed draws mostly foreigners. They were also angry about having to pay twice to get into the festival: once when they are taxed and once at the box office . . .

* Read Between the Lines Note: "A Doll's Life," the new musical directed by Harold Prince that carries on the story of Ibsen's heroine Nora after she leaves the doll's house, is closing its Los Angeles tryout run early. According to a spokesman for the show, the Mark Hellinger Theater, the Broadway house where the play is to open, became available earlier than expected . . . also the L.A. box office was slow . . .

* Typecasting Note: It was inevitable that Jurgen Prochnow, who made a large impression on the public playing the U-boat captain in "Das Boot," would be signed for his first American film, "The Keep." It was also inevitable what role he would play in this movie set in Romania during World War II: that of a Nazi captain . . .
