This ground-breaking collection of Italian madrigals was compiled over twelve years by scholars specializing in Renaissance music. The anthologies include prefatory materials covering the composer, the period, the music, performance practice, and appendices that include notes on the transcriptions, sources, and translations. Each of the anthologies in the series is beautifully engraved and bound in a 7 x 10 inch format suitable for performance or study. Individual numbers of the collections are also available (less the musicological material) as octavos. Listed below are the collections, and beginning on page 9, the individual numbers by voicing. While most are a cappella, some include either optional or required instrumental accompaniment as marked.
Volume 3 of The Flower of the Italian Madrigal (GM3214) and Luca Marenzio: The Complete Four Voice Madrigals (GM3215) are currently out of print, however, all the numbers from those 2 volumes are available as octavos. (See pages 31 and 32 for titles.
