7. The entire history of music is merely an illustration of these principles. Wherever there has been vigorous movement of mind and material prosperity (and they have always been associated) there has been an art of music, the richness of which, however, has always been limited by the state of the musical ears of the people or generation, and the perfection of their musical instruments. The instruments are an indispensable ingredient in musical progress, since it is only by means of instruments that tonal combinations can be exactly repeated, the voice mastering the more difficult relations of tones only when the ear has become quick to perceive tonal relations, and tenacious to retain them—in other words, educated. Hence in the pages following, the instruments peculiar to each epoch will receive the attention their importance deserves, which is considerably more than that usually allotted them in concise accounts of the history of this art.
8. The conditions of a satisfactory Art Form are three: Unity, the expression of a single ruling idea; variety, the relief of the monotony due to the over-ascendency of unity (or contrast, an exact and definite form of variety); and symmetry, or the due proportion of the different parts of the work as a whole. These principles, universally recognized as governing in the other fine arts, are equally valid in music. As will be seen later, all musical progress has been toward their more complete attainment and their due co-ordination into a single satisfactory whole. Every musical form that has ever been created is an effort to solve this problem; and analysis shows which one of the leading principles has been most considered, and the manner in which it has been carried out. Ancient music was very weak in all respects, and never fully attained the first of these qualities. Modern music has mastered all three to a very respectable degree.
9. The art of music appears to have been earliest of all the fine arts in the order of time; but it has been longer than any of the others in reaching its maturity, most of the master works now current having been created within the last two centuries, and the greater proportion of them within the last century. Sculpture came to its perfection in Greece about 500 B.C.; architecture about 1200 to 1300 A.D., when the great European cathedrals were built; painting about 1500 to 1600 A.D. Poetry, like music, representing the continual life of soul, has never been completed, new works of highest quality remaining possible as long as hearts can feel and minds can conceive; but the productions of Shakespeare, about 1650, are believed to represent a point of perfection not likely to be surpassed. Music, on the other hand, has been continually progressive, at least until the appearance of Beethoven, about the beginning of the present century, and the romantic composers between 1830 and the present time.

10. The history of music may be divided into two great periods—Ancient and Modern—the Christian era forming a dividing line between them. Each of these periods, again, may be subdivided into two other periods, one long, the other quite short—an Apprentice Period, when types of instruments were being found out, melodic or harmonic forms mastered; in other words, the tonal sense undergoing its primary education. The other, a Master Period, when an art of music suddenly blossoms out, complete and satisfactory according to the principles recognized by the musicians of the time. In the natural course of things such an art, having once found its heart, ought to go on to perfection; but this has not generally been the case. After a period of vigorous growth and the production of master works suitable to the time, a decline has ensued, and at length musical productivity has entirely ceased. Occasionally a cessation in art progress of this kind may have been dependent upon the failure of one or other of the primary conditions of successful art mentioned above, especially the failure of material prosperity. This had something to do with the cessation of progress in ancient Egypt, very likely; but more often the stoppage of progress has been due to the exhaustion of the suggestive powers of the musical instruments in use. The composers of the music of ancient Greece had for instruments only lyres of six or eight strings, with little vibrative power. After ten centuries of use every suggestion in the compass of these instruments to furnish, had been carried out. If other and richer instruments could have been introduced, no doubt Greek music would have taken a new lease of life, i.e., supposing that the material prosperity had remained constant.
The apprentice periods of ancient history extend back to the earliest traces of music which we have, beginning perhaps with the early Aryans in central Asia, whom Max Müller represents as circling around the family altar at sunrise and sunset, and with clasped hands repeating in musical tones a hymn, perhaps one of the earliest of those in the Vedas, or a still older one. From this early association of music with religious worship we derive something of our heredity of reverence for the art, a sentiment which in all ages has associated music with religious ritual and worship, and out of which has come much of the tender regard we have for it as the expression of home and love in the higher aspects.
All the leading types of instruments were discovered in the early periods of human history, but the full powers of the best have been reached only in recent times.
11. The art of music was highly esteemed in antiquity, and every great nation had a form of its own. But it was only in three or four countries that an art was developed of such beauty and depth of principle as to have interest for us. The countries where this was done were Egypt, Greece and India.
12. Modern music differs from ancient in two radical points: Tonality, or the dependence of all tones in the series upon a single leading tone called the Key; and Harmony, or the satisfactory use of combined sounds. This part of music was not possible to the ancients, for want of correctly tuned scales, and the selection of the proper tone as key. The only form of combined sounds which they used was the octave, and rarely the fifth or fourth. The idea of using other combined sounds than the octave seems to have been suggested by Aristotle, about 300 B.C. The period from the Christian era until about 1400 A.D. was devoted to apprentice work in this department of art, the central concept wanted being a principle of unity. After the beginning of the schools of the Netherlands, about 1400, progress was very rapid. The blossoming time of the modern art of music, however, cannot be considered to have begun before about 1600, when opera was commenced; or 1700, when instrumental music began to receive its full development. Upon the whole, the former of these dates is regarded as the more just, and it will be so used in the present work.
