Giovanni Pierluigi da Palestrina
Giovanni Pierluigi da Palestrina ( 1525 – 2 February 1594) was an Italian Renaissance composer of sacred music and the best-known 16th-century representative of the Roman School of musical composition. He had a lasting influence on the development of church music, and his work is considered as the culmination of Renaissance polyphony.
Knud Jeppesen
Jeppesen's name is invariably associated with the study of musical counterpoint, particularly in the style of Palestrina, of whom he was the leading scholar of his day. His 1930 work "Counterpoint: The Polyphonic Vocal Style of the Sixteenth Century" has been a standard textbook since its appearance in German (1935) and English (1939), and remains in print today (the third and final edition remains untranslated). His doctoral thesis was expanded in 1923 and appeared in English in 1927 as "The Style of Palestrina and the Dissonance" – a work which "The New Grove" cites as being the "most distinguished and influential example of stylistic analysis at this time".
