Antonio Vivaldi

**Antonio Vivaldi** (c.1675–1741) wrote at least three choral settings of the hymn *Gloria in excelsis Deo*, whose words probably date from the 4th Century and which is an integral part of the Ordinary of the Mass. Although two survive (RV 588 and RV 589) written in about 1715 the source of the edition used in Kalmus Study Score number 749 edited in 1967 by Clayton Westermann claims to be a faithful representation from the copy in the Biblioteca Nationale in Turin, Raccolta Renzo Giorano - Opere Sacre, (Tome 1 ff 90v—129r) and is traditionally divided into twelve movements. The Viennese **Edwin F. Kalmus** (b. Vienna 15 Dec 1893–d. New York 30 Apr 1989) founded a music publishing house in New York United States in 1926 concentrating on publishing classical musical works that had entered the public domain and making them widely available in inexpensive miniature reprint editions. However in 1976, the Kalmus company sold the study score, vocal, piano and chamber music titles to Belwin-Mills. The Kalmus Study Scores are a series of reduced size (mostly 5.25 by 7 inches) full scores in an easy-to-read format.
