Mendelssohn, in a letter to Zelter on the Palestrina music as heard in the Sistine chapel, says that nothing could exceed the effect of the blending of the voices, the prolonged tones gradually merging from one note and chord to another, softly swelling, decreasing, at last dying out. "They understand," he writes, "how to bring out and place each trait in the most delicate light, without giving it undue prominence; one chord gently melts into another. The ceremony at the same time is solemn and imposing; deep silence prevails in the chapel, only broken by the reechoing Greek 'holy,' sung with unvarying sweetness and expression." The composer Paer was so impressed with the wonderful beauty of the music and the performance, that he exclaimed, "This is indeed divine music, such as I have long sought for, and my imagination was never able to realize, but which, I knew, must exist." Palestrina's versatility and genius enabled him to lift ecclesiastical music out of the rigidity and frivolity characterizing on either hand the opposing ranks of those that preceded him, and to embody the religious spirit in works of the highest art. He transposed the ecclesiastical melody (_canto fermo_) from the tenor to the soprano (thus rendering it more intelligible to the ear), and created that glorious thing choir song, with its refined harmony, that noble music of which his works are the models, and the papal chair the oracle. No individual preeminence is ever allowed to disturb and weaken the ideal atmosphere of the whole work. However Palestrina's successors have aimed to imitate his effects, they have, with the exception of Cherubini, failed for the most part; for every peculiar genus of art is the result of innate genuine inspiration, and the spontaneous growth of the age which produces it. As a parent of musical form he was the protagonist of Italian music, both sacred and secular, and left an admirable model, which even the new school of opera so soon to rise found it necessary to follow in the construction of harmony. The splendid and often licentious music of the theatre built its most worthy effects on the work of the pious composer, who lived, labored, and died in an atmosphere of almost anchorite sanctity. The great disciples of his school, Nannini and Allegri, continued his work, and the splendid "Miserere" of the latter was regarded as such an inestimable treasure that no copy of it was allowed to go out of the Sistine chapel, till the infant prodigy, Wolfgang Mozart, wrote it out from the memory of a single hearing.
