Girolamo Scotto, Il primo libro delli madrigali a due voci nuovamente ristampati et da lui proprio con nuova giunta ampliati (Girolamo Scotto, Venice 1558).

info       title page

The first edition (1541) of this collection contains the largest number of duos and is better edited than the following ones because it has the most correct music and text. It includes all the madrigals but one – Io vorrei pur fuggir, crudel Amore – and all the motets. Otherwise, the six textless duos are included in 1558 only.
