McKinley wrote mainly for orchestra, and had pieces performed by the Philadelphia Orchestra and the New York Philharmonic. He also composed for organ, for chorus, and for piano, and wrote a handful of songs. He has been described as a "conservative modernist" who acknowledged that his own style borrows something from Richard Wagner.
He retired from the New England Conservatory in 1963, having reached the post of chairman of theoretical studies. Robert Cogan succeeded him.[1] He died in Centerville, Massachusetts, in 1966, aged 71.
