Music is made up of rhythms. Tones, from which we build melodies and harmonies, are produced by rhythmical vibrations (a certain number of vibrations per second produces a given note). In fact, the first three elements of music-melody, harmony, and tone color-are the result of the arrangement and "quality" of these rhythmical vibrations. What we usually refer to as "rhythm" includes the grouping of tones into "measures" of music, as well as the tempo at which these groupings are played or sung.
An interesting fact that may give us clearer insight as to why music has such power over the human frame is that we are also essentially rhythmical creatures. "There is rhythm in respiration, heartbeat, speech, gait, etc. The cerebral hemispheres are in a perpetual state of rhythmical swing day and night."*
Since both music and man are rhythmical, it is not difficult to understand why a person exposed to music begins to assimilate its beats. This is demonstrated when a person begins tapping the feet or exhibiting some kind of body movement in response to music. Thus, the body automatically alters its own rhythms to synchronize with the outside stimuli.
What is actually happening within the body is that "sound vibrations acting upon and through the nervous systems give shocks in rhythmical sequence to the muscles, which cause them to contract and set our arms and hands, legs and feet in motion. On account of this automatic muscular reaction, many people make some movement when hearing music."* It is because of this automatic rhythm emulation that music can alter us physically, mentally, and emotionally. The critical question, then, is which types of music or what part of music reacts adversely with our body functions and brings about these changes?
In 1987, scientists conducted a series of experiments to find out what kinds of music would be harmonious to body rhythms and what kinds would not. They divided 36 newborn mice into three groups: the control group, which was not exposed to music; the harmonic* group, which was exposed to simple classical music; and the disharmonic* group, which was exposed to disharmonic rhythms typical of rock music.
For two months, the harmonic and disharmonic groups were exposed to music night and day. After these two months, 12 mice-four from each group-were sacrificed and their brains were properly prepared and frozen for later study.
Next, the other 24 mice were exposed to three weeks of maze "training." Then they were given three weeks of rest, during which time no testing or maze reinforcement occurred. Finally, the mice were exposed to another three weeks of maze training to establish their degree of learning retention. Throughout this process, behavior changes and discrepancies were carefully noted. At the conclusion of the maze training, these 24 mice were sacrificed and their brains were studied along with those of the previous 12 mice.
The results of the study were sobering. The mice of the control and harmonic groups were very similar; no significant differences appeared. However, the disharmonic group showed a significant decrease in learning retention/memory, hyperactivity, and aggression. (During the three-month preliminary testing, some of the mice exposed to the disharmonic music resorted to cannibalism.) Some mice in the disharmonic group experienced lethargy and inattentiveness, while all experienced significant brain alterations.
Because of the nature of the study and the particular animals chosen for the experiment, we have every reason to believe that these same results occur in humans. This means that the rhythms typical of rock music are the main culprits: "disharmonic" music causes brain damage and behavior degradation. It is interesting to note that these behavioral changes are easily observable at any rock concert, as I mentioned earlier in the description of the Michael Jackson concert in Bucharest.
An added problem of rock music is the words of each song, which penetrate with force and seek to seduce the hearer. Once the person is mentally disoriented, the mind is then open to whatever suggestions the words may carry, whether it be sex, drugs, suicide, violence, abandonment, or even religion.
Because of the dangers inherent in this now-American legacy, it is important for Christians to guard themselves from its effects. We should learn to adjust our taste in music to that which is a melodic, purely "harmonic" style of music. In this style, the rhythmic groupings will always be very loyal to the naturally accented beats of the time signature (i.e., in 4/4 time, the first and third beats of the measure).
On the other hand, disharmonic music can most quickly be identified by its "swing" beat or syncopation, which moves the hearer away from the naturally emphasized beats (i.e., it emphasizes the second and fourth beats in a measure with 4/4 time). This off-beat syncopation tends to cause a side-to-side movement in the listener's body, thus distinguishing it as "dance" music. This side-to-side movement is a "telltale" sign that music has had a disorienting effect on the listener's body rhythms.
Because music enters directly into the autonomic nervous system, thus bypassing the master brain, the only time one can choose what happens to his body is before he listens to the music. Let's make those choices count on the side of healthy bodies and sound minds.
