However, it is believed that these chants were actually composed by multiple anonymous authors over the centuries, rather than solely by Pope Gregory I. They are an important part of the early Christian liturgical music tradition.

Most of the chants were created during the Early Middle Ages. The best known chants today are the Gregorian chants, which were compiled according to the wishes of Pope Gregory I, who was pope from 590 to 604.

The consensus of musicologists may be that the chants date from after the year 300. I have seen some disagreement on this, and there have been some important authors who have expressed the view that they were much older than that.

Very much so. Gregorian chants later in the Middle Ages started to become composed by artists who would write pieces for the church and pieces for secular crowds as well. So basically it was the artists that transitioned causing attention to the secular style of their pieces.

Early medieval sacred music had a homophonic, or one line structure, such as Gregorian chants. Its sole quality was free flowing with some syllables extended out over several notes. Gregorian chants evolved into Organum, which added several additional lines to the structure.
A salient characteristic of secular music from the Medieval period are strong, dance-like rhythms performed by a combination of instruments and voices.

* Genre: Classical There are arguments concerning the proper use of the term "Gregorian" in reference to chants. Generally the term refers to any chants written in the church modes, often employing texts from the psalms or the gospels. They developed during the papacy of Gregory the Great (d.604) but generally refer to the Church music of the 11th through 13th centuries. There is a distinction between Roman and Gregorian chants that obfuscates the origin and characterizes true Gregorian chant (that which developed with Gregory I and Gregory II), and Roman chants. There certainly are distinctions that scholars have drawn; however, the distinctions most accurately refer to different styles than to two different types of chants. The Gregorian chant contained phrases that are aesthetically pleasing to the eye often in the form of arches. Musical strains were often related to the text in the context of the contours of the musical line and what the text is addressing. Clearly there was also a balance between melisma and syllabic writing without an over abundance of the former. Though there were exceptions to the eight Church modes, most Gregorian chants were written in that vein. http://www.answers.com/topic/gregorian-chant

Pope Gregory the Great loved liturgical music and compiled all the chants that were being used throughout the Church. Later this music came to be called Gregorian Chant in his honor.

Created by Pope Gregory the chants are a form of music that praises God through the use of the voice only. There is no instruments involved. They are very soothing to listen too and are unlike any other music.

Franz Xaver Haberl was a German musician, musicologist, and conductor who was known for his work on Gregorian chant. He was the founder of the Paleographic Commission of the International Society of Music and a significant figure in the field of musicology.
