Dave Brubeck, Jazz Musician, Dies at 91 Dave Brubeck, a pianist and composer whose distinctive mixture of experimentation and accessibility made him one of the most popular jazz musicians of the 1950s and "60s, died Wednesday morning in Norwalk, Conn. He would have turned 92 on Thursday. He died while on his way to a cardiology appointment, Russell Gloyd, his producer, conductor and manager for 36 years, said. Mr. Brubeck lived in Wilton, Conn. In a long and successful career, Mr. Brubeck helped repopularize jazz at a time when younger listeners had been trained to the sonic dimensions of the three-minute pop single. His quartet's 1959 recording of "Take Five" was the first jazz single to sell a million copies. Mr. Brubeck experimented with time signatures and polytonality and explored musical theater and the oratorio, baroque compositional devices and foreign modes. But he did not always please the critics, who often described his music as schematic, bombastic and - a word he particularly disliked - stolid. His very stubbornness and strangeness - the polytonality, the blockiness of his playing, the oppositional push-and-pull between his piano and Paul Desmond's alto saxophone - makes the Brubeck quartet's best work still sound original. Outside of the group's most famous originals, which had the charm and durability of pop songs ("Take Five," "Blue Rondo à la Turk," "It's a Raggy Waltz"), some of its best work was in its overhauls of standards like "You Go to My Head," "All the Things You Are" and "Pennies From Heaven." David Warren Brubeck was born on Dec. 6, 1920, in Concord, Calif., near San Francisco. Surrounded by farms, his family lived a bucolic life: his father, Pete, was a cattle buyer for a meat company, and his mother, Elizabeth, was a choir director at the nearby Presbyterian church. When Mr. Brubeck was 11, the family moved to Ione, Calif., where his father managed a 45,000-acre cattle ranch and owned his own 1,200 acres. Forbidden to listen to the radio - his mother believed that if you wanted to hear music you should play it - Mr. Brubeck and his two brothers all played various instruments and knew classical études, spirituals and cowboy songs. Dave learned most of this music by ear: because he was born cross-eyed, sight-reading was nearly impossible for him through his early development as a musician. When he was 14, a laundryman who led a dance band encouraged him to perform in public, at Lions Club gatherings and Western-swing dances; he was paid $8 for playing from 9 p.m. to 4 a.m., with a one-hour break. But until he went to college he was an aspiring rancher, not an aspiring musician. At the College of the Pacific, near Stockton, he first studied to be a veterinarian but switched to music after a year. It was there that he learned about 20th-century culture and read about Freud, Marx and serial music; it was also there that he met Iola Whitlock, a fellow student, who became his wife in 1942. He graduated that year and was immediately drafted. For two years he played with the Army band at Camp Haan, in Southern California. In 1944 Private Brubeck became a rifleman, entering basic training - first in Texas, then in Maryland - and was shortly sent to Metz, in eastern France, for further preparation for combat. When his new commanding officer heard him accompany a Red Cross traveling show one day, Mr. Brubeck recalled, he told his aide-de-camp, "I don't want that boy to go to the front." Thereafter, Mr. Brubeck led a band that was trucked into combat areas to play for the troops. He was near the front twice, during the Battle of the Bulge, but he never fought. Finished with the Army at 25, Mr. Brubeck moved with his wife into an apartment in Oakland, Calif., and, on a G.I. Bill scholarship, studied at Mills College with the French composer Darius Milhaud. Milhaud asked the jazz musicians in his class to write fugues for jazz ensembles, and Mr. Brubeck played the results at a series of performances at Mills College. Mr. Brubeck had such admiration for his teacher that he named his first son, born in 1947, Darius. Daniel E. Slotnik contributed reporting. An earlier version of this obituary erroneously attributed a distinction to Mr. Brubeck. He was the second jazz musician to be featured on the cover of Time magazine, not the first. That version also misstated the name of a song at one point. It is "Take Five," not "Time Out." "Time Out" is the name of the album on which "Take Five" first appeared.
