Not only in the public functions, but in their domestic life as well, did music assume great importance. From earliest times we have records of folk songs associated with the various occupations of ordinary life. Of these the songs which have reference to the seasons of the year and their phenomena, and which express the emotions called forth by them, are of the greatest antiquity. They were sung by country folk, by the reapers and vintners. There were two distinct classes of folk songs, the songs of sorrow and the songs of joy, both of which existed according to Homer before his time. Karl Bücher in his _Arbeit und Rhythmus_ shows that in the occupational songs, where the dance did not form a part of the music, the rhythm of the occupations themselves--the handling of tools--determined the rhythm of the songs. Among such are the song of the miller while grinding, the song of the spinners, the binders of sheaves, and many others. There is no doubt that these songs, expressing in simple terms the sorrows and joys of the ordinary man, had a refreshing influence upon the more sophisticated artistic creations of Greek musicians, just as our folk songs have had upon the works of our greatest composers. The private practice of the more artistic forms was also common among the Greeks. We read in their literature how the lyre was passed round at the banquet, and each guest was expected to add to the merriment of the occasion; of the bridal songs, and many other forms of choral music executed upon special occasions.
