psalm tone

It is the oldest and most original psalm melody. The content is 150 psalms in the "Bible Old Testament". These psalms have different rhythms. Strictly, each sentence is of different lengths, with only the upper and lower sentences as the framework of one section, and mainly the steady and even repetition of homophones. It is a "syllabic" chant. Its form basically includes the introduction of "qi" (only used in the first verse), chanting sounds (sounds repeated with the same sound, singing a verse or sentence quickly), the "turn" in the middle (half-stop) and the end "He" (which is the most melodic part of the heart).

Antiphon

It was originally a way of singing psalms. The upper and lower lines of each stanza of the psalm were sung alternately by two choirs. Later, this alternating Part of it became independent and became the "Alternate Hymn", which belongs to the "Newham-style" hymn.

Responsory (responsory)

It is the most artistic form of Gregorian chant. Like the alternate chant, it originally refers to the singing form-the soloist leads the singing. A psalm in which the choir repeats the first half of the stanza. After that, the choir part chose other content as lyrics, and the melody became more and more fancy, becoming a unique 'response part'. It belongs to the "flower-singing" chant.

Hymn (hymn)

It is the only poetic form among the early Gregorian chants. It is "syllabic" and has strict rhythm

Hymn (canticle)

Similar to the melody of Psalms, but the lyrics are from other contents in the Bible, and the melody is slightly more decorative

Short verse (versicle)

With Sing in responsor form and sing content other than psalms.
