Definition

• Plainchant is a single line of melody, sung in unison without instrumental accompaniment. It is also known as Gregorian chant.

Historical Background

• The term 'plainchant' comes from the Latin 'cantus planus', meaning 'clear song'. It is one of the earliest forms of music notation known.
• It was primarily used in the Christian church liturgy, particularly in the Roman Catholic tradition. It originated around the 9th or 10th Century.
• Named after Pope Gregory I, who is traditionally believed to have ordered the codification of church music during his papacy from 590-604 AD.

Characteristics of Plainchant

• Plainchant is monophonic, which means it's made up of a single, unaccompanied melodic line.
• There is no regular metre in plainchant. Instead, the rhythm is dictated by the Latin liturgical text.
• Melodies are often narrow in range and are sometimes set to Latin texts.
• Several modes, scales used in plainchant, were used to create different moods, providing variety to the music. Modes used in plainchant are known as church modes.

Types of Plainchant

• There are several types of plainchant, including responsorial and antiphonal chants. In responsorial singing, a soloist or small group sings verses that are responded to by the full choir. In antiphonal singing, two halves of the choir sing in alternation.
• Another type is the Gregorian chant, named after Pope Gregory the Great, which is the most well-known type of plainchant.

Significance of Plainchant

• Plainchant had a considerable influence on the development of Western music, contributing significantly to the evolution of musical notation.

Listening

• Listening to various examples of plainchant can help understand the simplicity, tranquillity, and spirituality associated with this style of music.
