Britten’s Blake cycle returns in places to the dark intensity of his much earlier Blake setting, ‘The Sick Rose’ (‘Elegy’) from the Serenade for tenor, horn and strings of 1943. Both the fully chromatic melody and striking image of cankerous corruption in the earlier song look directly ahead to the Songs and Proverbs—which are based on texts drawn from Blake’s Songs of Experience (1794), in which ‘The Sick Rose’ is also to be found. With the addition of one poem from the Songs of Innocence (1789) and several epigrams from the undated Proverbs of Hell, Britten created a continuous structure in which the Proverbs are set to recurrent but constantly reworked ritornello material, a structural plan familiar from other Britten works of the late 1950s and early 1960s (principally the orchestral song-cycle Nocturne, the opera A Midsummer Night’s Dream and the Cantata Misericordium). These stark Proverbs are clearly distinguished from the songs they punctuate by their disconcerting lack of metrical synchronization between voice and piano—a feature retained from the Church Parable Curlew River, composed in the previous year—and they also make limited use of twelve-note techniques.
As so often in Britten’s later music, the tension between luminous diatonicism and elusive chromaticism is exploited throughout the cycle as a potent symbol for the conflict between innocence and experience at the heart of Blake’s poetry. The settings of ‘London’ and ‘Every Night and every Morn’ that frame the cycle are closely related in their ambiguous and subtly disturbing chromaticism, while greater tonal simplicity is reserved for natural scenes: the bright glow of ‘The Tyger’ and the lament for ‘The Fly’. Moments of tremendous rhetorical power are strategically located in ‘A Poison Tree’ and ‘Ah, Sun-flower’. ‘A Poison Tree’ features a highly original use of simple major and minor triads within a context of chromatic saturation. The young Britten had previously set this same Blake text to music on 2 March 1935; the earlier song remained unperformed until 1986. As in the opera The Turn of the Screw (1954), the intense chromaticism of the mature treatment of this gripping text serves as a graphic symbol of cankerous evil, and forms the utterly chilling core of the cycle.
