Pierre Phalèse the Elder (alias Petrus Phalesius, circa 1510-circa 1575) was an important Flemish music editor and engraver of the sixteenth century. Phalèse was born in Leuven about 1510 where he started as a bookseller in 1545, but soon set up a publishing house, and by 1575 had produced some 189 music books. Phalèse at first outsourced his books to various printers, but by 1553 was printing his own high-quality output from movable type. In 1570 he entered into partnership with Jean Bellère, a printer based in Antwerp, enabling him to reach a wider clientèle. The majority of Phalèse's output is dedicated to sacred music – masses, motets and magnificats - the rest being a mix of French chansons, Italian madrigals, Flemish songs and instrumental works. Phalèse borrowed from many composers and did not hesitate to include works from collections of other publishers. Many pieces are by Clemens non Papa and other Flemish composers such as Lassus and Rore, while some of his instrumental pieces are obviously borrowed from the Parisian publishers Le Roy and Ballard. Notable among these is Selectissima... in guiterna ludenda carmina (Louvain, 1570), a collection containing instructions (in Latin) for amateurs wishing to play the guitar, together with 115 pieces for that instrument. In the same year Phalèse published a collection of music for cittern under the title Hortulus cytherae.
