The Souterliedekens is a Dutch metrical psalter, published in 1540 in Antwerp, and which remained very popular throughout the century. The metrical rhyming psalms were, probably, arranged by a Utrecht nobleman: Willem van Zuylen van Nijevelt. For the melodies he used folksongs from the Low Countries. This publication has great value, because the publisher not only added the phrase 'sung to the tune of...' but also provided the actual music (melody) with the texts.
