Ranieri de' Calsabigi came to Vienna in 1761, after making himself known by an edition of Metastasio's works, with an aesthetic introduction proving their perfection as tragedies and operas; he had also written several libretti for operas and cantatas. He had formed an idea that music fitted for dramatic poetry must approach as nearly as possible to natural, energetic declamation; for since declamation was only unperfected music, dramatic song could only be elaborated declamation enriched by the harmonies of the accompaniment. The poetry for such music must be intense, forcible, passionate, moving, and harmonious, and it could not fail of its result. Full of this idea he wrote "Orfeo," and submitted it to Count Durazzo; the latter wished it to be put on the stage, and recommended Gluck as the composer who could best carry out the intentions of the poet. Calsabigi declaimed his "Orfeo" repeatedly before Gluck, and noted his declamation in the text-book with signs which he illustrated by remarks.[61] Gluck, while giving full justice to the impulse {FRENCH OPERA.} (20) which he had received from his poet,[62] could only partially yield to his whimsical exaggeration of declamatory music. But Calsabigi's ideas accorded with his own so far as to aid him in giving them clearness and precision. Gluck's demands on the musical drama went farther and deeper than Calsabigi's comprehension and powers could reach.[63] But in the meantime he accepted what was offered to him, and so were produced "Orfeo ed Euridice" (1762), "Alceste" (1767), and "Paride ed Elena" (1769).
