In the course of preparing a study of Lasso's Libro Quarto of five-voice madrigals (1567), my attention was drawn to the Libro Primo de Madrigali a 6 voci of Giovan [Jean, Jan] Turnhout, published in Antwerp in 1589, in which a large number of pieces–half the contents of the book–are settings of texts used by Lasso. One Netherlandish composer turning to the work of an older and more famous compatriot, to be sure. That is easily said; but sixteenth-century musicians did not have access to the resources of modern libraries, and the whole question of how madrigalists came upon the texts they set is a far from simple one. Turnhout was not, to judge from this volume, a serious student of Lasso's music; his madrigals are far closer in style to the canzonetta of the 1570s and 1580s than they are to Lasso. A few fleeting allusions tell us none the less that he did see not only the texts but the music of the older composer, and indeed music prints must have been an important source for composers in search of texts to set, even if their purpose was not musical parody. Is there some reason for Turnhout to have seen volumes of Lasso madrigals and to have chosen, or have recommended to him, the texts he set?
