What kind of music is Gregorian chant?

In the early Middle Ages, European churches used several different religious ritual songs. Byzantine hymns combine elements of ancient Greek and oriental music and adopt eight classification modes. Ambrosi hymn is a hymn compiled by Saint Ambrosi of Milan (Bishop of Milan, 374-397), who introduced Syrian duet hymns to Western Europe for the first time and created popular hymns. In addition, there are Franck's Gaul hymn and Spanish Mosala Bakenz.

It is said that at the end of the 6th century AD, Pope Gregory I (reigned from 590 to 604) collected the ritual songs and hymns used by various churches into an aria called Gregorian hymns.

There are two extant early Gregorian chants. One is the hymn in Frank style, which was circulated in the Frankish kingdom in the 8th and 9th centuries. This is a transcript handed down by Charlemagne, the king of Frank, who vigorously promoted the standard Roman mass ceremony and hymns in the vast area under his rule. The other is the ancient Roman version of 1 1 to 13. According to textual research, its history can be traced back to the 8th century.

Gregorian chant is monophonic music, Latin words, male singing, and the score is just a pitch record without beat. Gregorian chants are mainly used for daily prayers and mass ceremonies in Catholic churches. It has a strong religious concept and function, pursues the spirit of transcending the secular "other shore" and avoids the secular individual feelings.

Some words of Gregorian hymns are taken from the Bible, some are essays, and some are poems. Singing methods include: duet (two groups of chorus alternate), chorus (lead singer and chorus response) and solo or chorus. There are three main melody types: syllable, the lyrics of a Latin syllable and a sound; Flowers sing, one word at a time; Singing, between the first two, a syllable sings 2 to 4 or 5 notes. There are eight types of Gregorian hymns: Doria, Frikia, Lydia and mixed Lydia, and four different styles are derived from them.
