"Music is considered to have three primary parts: melody, harmony, and rhythm. ... The most prominent part of the music should be the melody. It is the horizontal arrangement of sounds which is recognized first when we sing a song like `When I Survey the Wondrous Cross.' . The harmony is the vertical aspect of the music, or the chords of the music. It is the sounds which are heard when the individual parts coincide. In what is called homophonic music, the voices sound simultaneously most of the time. By contrast, in polyphonic music in which the individual voices are more independent, the harmony is less pronounced because of the dominance of the melodic lines and their linear movement. The rhythm makes the music move. If it were not for the rhythm, the music could not progress-it would stand still as one continuous, quickly boring, and uninteresting sound.
"The part of music to which the spirit responds is the melody. Ephesians 5:18-19 gives us a clear indication the part of music which God wants to be preeminent in the music of a Christian. Verse 18 commands us to be `filled with the spirit.' The word `filled' literally means `to be controlled.' The very next verse then states that we should be `making melody.' The words translated `singing and making melody' in Ephesians 5:19 come from two Greek words: adontes, meaning `singing' and psallontes, meaning `psalming,' or `putting music to poetry' (setting poetry to music), which is what the word melody means. Melody comes from two Greek words, meloidia meaning `choral song,' derived from melos, tune, plus aoidein, `to sing.'... This instrumental term refers to the music and only by implication to the words. Thus, when the King James Version of Scripture follows the command to be filled with the Spirit with the musical form melody, it is accurately teaching that this element of music and God's control in our lives are closely related.
"The part of music to which your mind responds is the harmony. Harmony is the intellectual part of music. Extensive training and a disciplined lifelong study are required to write and understand music with correct harmony. ... A correct, good-sounding, mood-producing harmony can be arranged and effectively written only by a trained musician. The word harmony, ultimately from the Greek word for `joint,' suggests the idea of fitting together. The harmony joins the melody and the rhythm together.
"The part of music to which your body responds is the rhythm. The Greek word from which the word rhythm comes is rheo, which means `to flow,' or `to pulse.' Although this word is not used in relation to music in the Bible, its meaning and use do give some insight concerning rhythm in music. For instance, Jesus used this word in John 7:38 when He said, `He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.' The rhythm is the pulse of the music, and the analogy between the pulse and rhythm will help any desirous Christian to gain discernment in his choice of music.
Too much (or erratic pulse Body is sick
Too much (or erratic rhythm Music is sick
No pulse Body is dead
No rhythm Music is dead
Pulse under contro Body is well
Rhythm under control Music is `well'
"Rhythm is the physical part of music.
"The Christian with a Scriptural order and balance in his life emphasizes the spiritual first (Matthew 6:33), the intellectual or emotional second (2Co 10:5), and the physical last (Romans 13:14). Consider also Proverbs 3:5-6 and Luke 12:31.
"Just as the spiritual considerations of life receive priority by the balanced Christian, so the melody (that part of music to which the spirit responds) must dominate the music in the Christian's life. Similarly, the harmony (that part of music to which the mind and emotions respond) needs to have a supportive role in music, just as the mind and the emotions play a secondary role in the Christian experience. Last, and most obvious, the rhythm (that part of music to which the body responds) must be under strict control in music, just as the body and its desires need to be disciplined in the Christian's life. If we genuinely want to do right and understand, then these concepts become extremely sensible and logical. But frequently, as in other areas of the Christian life, our tastes, preferences, and opinions blur our vision and interfere with comprehension. Consider Paul's words as he speaks of the body: `For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live (Romans 8:13). `But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway' (1 Corinthians 9:27).
"The body must be in proper relationship with the mind and spirit. It is not that rhythm should be abandoned, but it needs to be in proper balance with the harmony and the melody. ...
"If the body and physical things are a priority in one's life, that person is sensual. If the rhythm is the primary dominating part of any piece of music, then that music is sensual. ...
"The pulse is there to sustain life. It does not call attention to itself in that role. Rhythm should play the same part in music. It is there to keep the music moving, not to dominate the sound"
