 Seattle's music history begins in the mid-19th century, when the first European settlers arrived.In 1909, amidst the boosterism engendered by the city's first world's fair, the Alaska-Yukon-Pacific Exposition, the Seattle City Council adopted "Seattle, the Peerless City" (words by Arthur O. Dillon; music by Glenn W. Ashley) as Seattle's official song.By the early 20th century, Seattle had an upper-class society that established an urban culture, which included music; the city's high culture was, however, shadowed by that of San Francisco, which was then the major cultural center of the West Coast.
