Handel L'Allegro IL Penseroso Ed IL Moderato - Vocal Score - English and German Text. This oratorio is based on 2 poems of 1623 by John Milton. Their main focus draws on merriment, as expressed in the joys of the dawn, the hunt, a pastoral idyll and thriving towns: and on melancoly, as felt in the coolness of the nocturnal forest, a song of the nightingale, and the observation of the stars. Handel has written a lyric work that gives broad latitude to the musical depiction of nature.
