The principal influence of these different classes of popular minstrel was temporary, in keeping alive a love for music and a certain appreciation of it. The most of their music was rather slow and labored, and it is impossible to discover in the later development of the art material traces of their influence upon it. In this respect they differ materially from the Celtic and English bards mentioned in the previous chapter. Although the productions of those minstrels have all passed away, they have left a distinct impress upon musical composition, even to our own day, in certain simple forms of diatonic melody of highly expressive character. The troubadours, trouveres and minnesingers, on the other hand, never acquired the art of spontaneous melody, and as for harmony, there is no evidence that they made any use of it. Their instrument of music was a small harp of ten or twelve strings, but no more--a much smaller and less effective instrument than the Irish harp of the eleventh century, or the Saxon of the tenth. (See Fig. 28.) [Illustration] CHAPTER X. THE INFLUENCE OF THE CHRISTIAN CHURCH. It is not easy to define the influence of the Christian Church in this transformation, for the reason that upon the technical side it was slight, although upon the aesthetic side it was of very great importance. From the circumstance that all the early theoretical writers from the sixth century to the thirteenth were monks or ecclesiastics of some degree, and from the very important part played by the large cathedrals in the development of polyphonic music, many historians have concluded that to the Church almost this entire transformation of the art of music is due. This, however, is wide of the truth. The Church as such had very little to do with developing an art of music through all the early centuries. The early Christians were humble people, for the most part, who had embraced a religion proscribed and at times persecuted. Their meetings were private, and attended by small numbers, as, for instance, in the Catacombs at Rome, where the little chapels in the dark passage ways under ground were incapable of holding more than twenty or thirty people at a time. Under these circumstances the singing cannot have been essentially of more musical importance than that of cottage prayer meetings of the present day. In another way the Church, indeed, exercised a certain amount of influence in this department as in all others, an influence which might be described as cosmopolitan. The early apostles and bishops traveled from one province to another, and it is likely that the congregation in each province made use of the melodies already in existence. The first Christian hymns and psalms were probably sung to temple melodies brought from Jerusalem by the apostles. As new hymns were written (something which happened very soon, under the inspiration of the new faith and hope), they were adapted to the best
