Morello, who was 82, was best known for his work with the Dave Brubeck Quartet. He was a member of the group for more than 12 years and was featured on such jazz classics as "Take Five" and "Blue Rondo a la Turk."
Morello also played with many leading jazz musicians over the years, including pianist Marian McPartland's Hickory House Trio in the early '50s.
After Brubeck disbanded the quartet in 1968, Morello turned to teaching and writing instructional books.
