note: See BridgmanM, 200-1. It is unclear whether the cc. incipits refer to Giustinian’s lauda ‘Regina del cor mio a te con mente pia’, or to his canzonetta, ‘Regina del cor mio non ti par tempo ancora’, though probably the latter since Ch266 transmits the lauda text with the full incipit of the secular song as its cc. The secular text is in RA2435, pp. 144-5, and ed. in Wiese, 225-8; the lauda text is ed. in LuisiLG, i, 285-6. Music in Grey à2 (prob. a contrafactum), a setting of the lauda text, ed. CattinG, no. 14 (notes on p. xxi), and LuisiLG, ii, 120. Different music a3 in P676. A rubric in RA2274, fol. 298v indicates that Antonio di Guido wrote his lauda for Giovanni di Cosimo de’ Medici ‘alle Murate’ (at the convent of the Murate, or for performance at the convent).
