Gounod wrote twelve operas, in a variety of the genres then prevailing in France. "Sapho" (1851) was an early example of opéra lyrique, smaller-scale and more intimate than grand opera but through-composed, without the spoken dialogue of opéra comique. Berlioz wrote of it, "Most of the choruses I found imposing and simple in accent; the whole third act seemed to me very beautiful ... But the quartet in the first act, the duet and trio in the second, where the passions of the principal characters break out with such force, absolutely revolted me". A more recent reviewer remarks on Gounod's "genuine talent for music-drama ... exercised in the Quartet of Act 1 where each character has an independent part, making effective counterpoint in dramatic as well as musical terms". Gounod revised the work in 1858 and again, more radically, in 1884, but it was never a success. The one fairly well known number from the score, Sapho's "O ma lyre immortelle", is a reworking of a song he had composed in 1841.
