Summer nigths (les nuits d'eté) Op. 7 is a song cicle by Berlioz. A setting of six poems by Théophile Gautier. The collection was completed in 1841 and initially composed for tenor and mezzo-soprano, later arranged for baritone, contralto, or soprano, and piano. Berlioz later gave it full orchestra accompaniment, almost all modern performances stem from this version. The title of the collection is, of course, a nod to Shakespeare.
