![]() ![]() Those are natural stopping places when finding new notes above a starting note, whether you're using a vibrating string or air in a pipe. There's a more technical discussion of this in the appendix of Exploring Theory, but basically it means that the ear will hear a noticeable agreement between tones that are an octave apart, or a fifth apart, and to a lesser degree to notes that are a fourth or a major third apart, etc. Take two pitches that at first have no apparent relation to each other, gradually change one, and at certain points they will suddenly come into a kind of agreement that is quite audible: that is the effect of the overlapping partials. And when you play two musical tones together that are tuned just right, some of these other waves, called "partials," will correspond and will reinforce each other so that these combinations seem particularly important. There will be a tone that corresponds to the main shape, one that is twice as fast, which is an octave higher, one that is three times as fast, which is a "fifth" above that, and so on. In that complex sound that makes up a single musical tone there will actually be found a number of pitches combined. ![]() And the shape of the repeating wave gives a different type of sound: a relatively smooth wave for a flute a rougher one for a violin. ![]() If it repeats quickly we hear a high tone, if slowly we hear a low one. Look at the graph of a musical sound and you'll see some kind of shape that repeats over and over. If you look at a graph of the sound wave produced by, say, a sneeze, you'll see an irregular and unique jumble. Musical tones are those that have a recognizable pitch, which means that the sound wave repeats a pattern rather than changing constantly. The basic elements of music are not arbitrary, but result from the nature of vibrating strings or columns of air. But there are going to be a lot of words. Let's try, with an attempt to explain a few terms as we go. It's hard to avoid all technical talk in making an answer. This is the musical equivalent of asking where the universe came from. And the answer is not immediately obvious, either. Question: Why is there only A-G on the chromatic scale? I know, "because music is this way so they came up with this scale to name it." But WHY is music this way? WHY is it only 8 note and then starts over? (Please speak plainly and simply.)- GraceĪnswer: I really love this kind of question. Why are there only seven note names? Why are there only seven note names? ![]()
