Avo Sõmer (born 1934) is an American musicologist music theorist, and composer, of Estonian birth. Sõmer was born in Tartu, Estonia. He emigrated from Estonia with his parents in 1944, when he was ten years old, first to Germany and then to the United States. He had already begun playing the piano as a child in Pärnu. In Germany he took some piano lessons and instruction in theory, and began to compose, but systematic instruction in music came only later. He majored in music education, piano performance, and composition at Wayne State University in Detroit, Michigan, followed by graduate studies at the University of Michigan where, in 1957, he earned an M. A. with a thesis on Monteverdi's madrigals, and then, in 1963, a PhD with a dissertation "The Keyboard Music of Johann Jakob Froberger"
