Note 3 — Chapter I · MUSIC OF THE EARLY AND MEDIÆVAL CHURCH AND EARLY SECULAR MUSIC

Practically all the music of these ancient collections has been lost, excepting the Spanish or Mozarabic or Visigothic. Recent discoveries have disclosed a considerable portion of the music of this branch of the Church, so that we have some definite information concerning at least three ancient ecclesiastical dialects of ritual-music—the Gregorian, the Ambrosian, and the Visigothic or Mozarabic. In a few Spanish churches the Mozarabic rites and music still survive.
