Prattica di musica, utile et necessaria si al compositore per comporre i canti suoi regolatamente, si anco al cantore per assicurarsi in tutte le cose cantabili

This book is the first part of Lodovico Zacconi's "Prattica di musica," published in 1596. The contents of this book are divided in four parts covering: the history of music, definition of musical terms, introduction to musical notation, modes, time and prolation, rules of counterpoint, musica ficta, classification of musical instruments, and proper manner of singing polyphonic works and musical ornaments. A second part, "Prattica di musica seconda parte," was published in Venice in 1622. \ud \ud The library's copy contains the following pagination errors: leaves 30, 67, 124, 130, 134, 188 were numbered incorrectly as 29, 140, 130, 122, 130, 194, respectively. \ud \ud There are two leaves numbered 50, each containing the parts for the alto, bass and tenor with underlaid text "Beatus author seculi" and "Residuo." Each leaf is preceded by another leaf that contains the singing parts for the cantus, quintus and tenor. These are two versions of a polyphonic setting, in duple time and triple mensuration, respectively. In the second example, the words Gloria tibi domine" appear under the cantus and quintus
