The Renaissance Reform of Medieval Music Theory, (Hardcover)

Modern scholars have often portrayed the method of hexachordal solmization - the sight-singing method introduced by the 11th-century monk Guido of Arezzo - as the diatonic foundation of early music.

Stefano Mengozzi challenges this view by examining a representative sample of the primary sources of solmization theory from Guido of Arezzo to Gioseffo Zarlino.

These texts show that six- syllable solmization was only an option for sight-singing that never imposed its operational 'sixth-ness' onto the diatonic system, already grounded on the seven pitch letters.
