Born in
Taos, New Mexico on January 13, 1939, Cheetham grew up with a musical background. In 1962, he went on to attend the
University of New Mexico where he earned both bachelor's and master's degrees in music. During his attendance at the university, he became the first trombonist in the campus orchestra, which was known as the
New Mexico Symphony Orchestra until 2011. This allowed him several opportunities for exposure to new literature, which broadened his musical perspective. In 1965, Cheetham attained a Doctor of Musical Arts in composition from the
University of Washington. ==Personal life==
