When asked about his musical style in the discussion preceding the 2009 premiere of his opera The Dawn Makers, Shearer answered that it varies according to the demands of the medium. Critics also describe it variously. The Harvard Biographical Dictionary of Music observes that Shearer’s music, "though it recalls postwar serialism in its rhythms and textures, relies on traditional counterpoint and on tonal centers."[2] Its lyric quality is frequently cited: Jeff Rosenfeld, reviewing Shearer’s Outbound Passenger, found the music "tuneful and harmonious;"[3] and of Shearer’s cantata King Midas, critic Robert Commanday wrote, ‘The singing lines are fluid and supple, animated, alive; the harmony and scoring for a quintet of instruments and percussion battery (two players), rich but delicately so."[4] In the British periodical Opera, Allan Ulrich wrote that the score of Shearer’s chamber opera The Dawn Makers has "genuine personality. The hour-long opera abounds in extended ariosos and bravura outbursts and unfurls in a conservative idiom, spiced with dissonances which neatly evade the neo-Romantic pitfalls that prevail in American opera circles."[5] Of the same work, Thomas Busse wrote in San Francisco Classical Voice, "The music’s greatest strength was its singability, attributable to the composer’s being a vocalist himself. I would describe Shearer’s eclectic style as more declamatory than lyrical."[6] Of Shearer's opera Middlemarch in Spring[7] Janos Gereben wrote in the San Francisco Examiner, "Shearer's music is pleasantly dissonant, with a sound that sticks in the ears and memory. It's ambiguous music, seemingly wondering [sic] between keys, but landing securely each time."[8]
