Hovhaness was inducted into the National Institute of Arts and Letters (1951), and received honorary D.Mus. degrees from the University of Rochester (1958), Bates College (1959) and the Boston Conservatory (1987). He moved to Seattle in the early 1970s, where he lived for the rest of his life. In 1973, he composed his third and final ballet score for Martha Graham: "Myth of a Voyage", and over the next twenty years (between 1973 and 1992) he produced no fewer than 37 new symphonies.
