Willie Ruff

Ruff was awarded with the Sanford Medal in May 2013. The Sanford Medal is the highest honor from Yale University's School of Music.

Ruff is known for uncovering links between traditional black gospel music and unaccompanied psalm singing. Ruff's theory is that the Scottish Presbyterian practice of lining out – in which a precentor read or chanted a line of the psalm, which was then sung by the congregation – led to the call and response form of black gospel music. Ruff co-created the documentary "A Conjoining of Ancient Song", which focuses on a rapidly vanishing form of congregational singing that is shared by Scottish, African American, and Native American music. It received its world premiere screening at Yale in 2013. Ruff's work in this area is also a subject of Sterlin Harjo's 2014 documentary film, This May Be the Last Time.

Ruff received the Connecticut Governor's Arts Award in 2000 for his work with the Duke Ellington Fellowship Program.

He is a 1994 inductee of the Alabama Jazz Hall of Fame.

In 1992, Ruff published his memoir, titled A Call to Assembly: The Autobiography of a Musical Storyteller. The autobiography was hailed as "an unmitigated delight" and was awarded the ASCAP Deems Taylor Award.

He is one of the founders of the W. C. Handy Music Festival in Florence, Alabama. The first festival was held in 1982.

In 1976-1977, he held a visiting appointment at Duke University, where he oversaw the jazz program and directed the Duke Jazz Ensemble.

He is founding Director of the Duke Ellington Fellowship Program at Yale, a community-based organization sponsoring artists mentoring and performing with Yale students and young musicians from the New Haven Public School System. The program was founded in 1972 as a "Conservatory Without Walls" to "'capture the essence and spirit' of the tradition of African-American music". By its 30th anniversary in 2002, the program had reached an estimated 180,000 students in New Haven schools.

Ruff was a faculty member at the Yale School of Music from 1971 until his retirement in 2017, teaching music history, ethnomusicology, and arranging. Ruff's classes at Yale, often with partner Dwike Mitchell, were free-flowing jam sessions: roller-coaster rides through the colors of American Improvisational Music. The duo could play in the style of most notable jazz artists and related styles. They had a large repertoire.

Ruff was chosen by John Hammond to be the bass player for the recording sessions of Songs of Leonard Cohen, an album first released in 1967. During those sessions, he and Cohen laid down the bed tracks for most of the songs on the album.

Ruff attended the Yale School of Music as an undergraduate (Bachelor of Music, 1953) and graduate student (Master of Music, 1954).

Ruff played in the Mitchell-Ruff Duo with pianist Dwike Mitchell for over 50 years. Mitchell and Ruff first met in 1947, when they were teenaged servicemen stationed at the former Lockbourne Air Force Base in Ohio; Mitchell recruited Ruff to play bass with his unit band for an Air Force radio program. Mitchell and Ruff later played in Lionel Hampton's band but left in 1955 to form their own group. Together as the Mitchell-Ruff Duo, they played as "second act" to artists such as Louis Armstrong, Count Basie, Duke Ellington, and Dizzy Gillespie. From 1955 to 2011, the duo regularly performed and lectured in the United States, Asia, Africa, and Europe. The Mitchell-Ruff Duo was the first jazz band to play in the Soviet Union (1959) and in China (1981). Mitchell died in 2013.
