André Previn, 89, who blurred the boundaries between jazz, pop and classical music — and between composing, conducting and performing — in an extraordinarily eclectic, award-filled career, died Thursdayat his home in Manhattan.

Previn wrote or arranged the music for dozens of movies and received four Academy Awards. Audiences knew him as a jazz pianist who appeared with Ella Fitzgerald, among others, and as a composer who turned out musicals, orchestral works, chamber music, operas and concertos, including several for his fifth wife, violinist Anne-Sophie Mutter. He was also the music director or principal conductor of a half-dozen orchestras.

Ira Gitler, 90, who was one of the most respected and prolific jazz writers of the postwar era and an early champion of bebop, died Feb. 26 in Manhattan.

In 2017, Gitler was named a Jazz Master by the National Endowment for the Arts. “He had a terrific ear, and could not be fooled by reputation, no matter how venerated,” jazz writer Gary Giddins said in an email. “Musicians respected him; they considered him one of the tribe. You can’t say that about a lot of critics.”

Dorothy Masuka, 83, a vocalist and songwriter who blazed a trail for female pop stars in South Africa and became a dogged advocate of the struggle against apartheid, died Feb. 26 at her home in Johannesburg. The cause was complications of a stroke Masuka suffered last year while touring Europe.
