Symphonie espagnole Symphonie espagnole The Symphonie espagnole in D minor, Op. 21, is a work for violin and orchestra by Édouard Lalo. The work was written in 1874 for violinist Pablo Sarasate, and premiered in Paris in February 1875. Although called a "Spanish Symphony" (see also Sinfonia concertante), it is considered a violin concerto by musicians today. The piece has Spanish motifs throughout, and launched a period when Spanish-themed music came into vogue. (Georges Bizet's opera "Carmen" premiered a month after the "Symphonie espagnole".) The "Symphonie espagnole" is one of Lalo's two most often played works, the other being his Cello Concerto.
