I am concerned with Christ: He ordained HIS School of the Word in the FIRST CENTURY. I personally do not know what all churches of Christ do.
I seem to be the only one who has discovered that SPEAK is the opposite of SING or people just don't want to give up their career path.
The Church of Christ (the Rock) was ordained in the wilderness after the nation was split because of musical idolatry at Mount Sinai on the Rest day. The command excluded "vocal or instrumental rejoicing or rhetoric."
Hymnody developed systematically, however, only after the emperor Constantine legalized Christianity (AD 313); and it flourished earliest in Syria, where the practice was possibly taken over from the singing by Gnostics and Manichaeans of hymns imitating the psalms. The Byzantine Church adopted the practice; in its liturgy, hymns maintain a much more prominent place than in the Latin liturgy; and Byzantine hymnody developed complex types such as the kanon and kontakion (qq.v.; see also Byzantine chant). Saint Ephraem--a 4th-century Mesopotamian deacon, poet, and hymnist--has been called the "father of Christian hymnody." Britannica Online
In the West, St. Hilary of Poitiers composed a book of hymn texts in about 360. Not much later St. Ambrose of Milan instituted the congregational singing of psalms and hymns, partly as a counter to the hymns of the Arians, who were in doctrinal conflict with orthodox Christianity [WORSHIP WARS] In poetic form (iambic octosyllables in four-line stanzas), these early hymns--apparently sung to simple, possibly folk melodies--derive from Christian Latin poetry of the period. By the late Middle Ages trained choirs had supplanted the congregation in the singing of hymns. Although new, often more ornate melodies were composed and many earlier melodies were elaborated, one syllable of text per note was usual. Some polyphonic hymn settings were used, usually in alternation with plainchants, and were particularly important in organ music.
Congregational singing in the liturgy was re-established only during the Reformation, by the Lutheran Church in Germany.
The early chorale (q.v.), or German hymn melody,
was unharmonized and sung unaccompanied,
although harmonized versions,
used by varying combinations of choir, organ, and congregation,
Swiss, and later, French, English, and Scottish Calvinism promoted the singing of metrical translations of the psalter (see psalmody), austerely set for unaccompanied unison singing. English and Scottish Protestantism admitted only the singing of psalms. English metrical psalms were set to tunes adapted from the French and Genevan psalters. These were fairly complex melodies written on French metres. The English psalter used only a few metres, and the custom of singing each psalm to its “proper” tune was soon replaced by the use of a few common tunes. The common metre 8, 6, 8, 6 (the numbers give the number of syllables in each line), a form of English ballad metre, remains the archetypal English hymn metre.
You can do what you are gonna do but you cannot focus on MUSIC and be a New Testament Christian or Church.
I know that once you have been sorcerized with music it is hard to catch on but:
The command is to SPEAK that which is written for our learning. Psalms, hymns and spiritual songs are in the BOOK OF PSALMS.
Nothing written for our learning is in lyric poetry.
Therefore, neither then nor now can you be a follower of Christ and sing YOUR OWN STUFF and set it to MELODY.
