Music in Mohammedan countries has peculiarities which differentiate it quite distinctly from music in China and in India. In India music has always been largely associated with religion, especially in connection with the dance. Mohammedanism has never encouraged religious music. It is true that the chanting of the muezzin calls the faithful to prayer from the minarets; but except this the music which accompanies the dances of the whirling dervishes of Cairo, Bagdad, and Constantinople offers practically the only example of Mohammedan religious music.[17] Nevertheless in the brilliant days of the Abbaside caliphs and the Moorish kings of Spain music was a passion with the Saracens. Haroun-al-Raschid lavished rewards of gold and lands on his musicians and the 'Thousand and One Nights’ proves in what esteem music was held throughout the Mohammedan Orient at the time of the Caliphate. There was a rich and elaborate musical literature, but the decadence of the Arab civilization brought with it entire oblivion of the many treatises and writings of these glorious days. The old science is forgotten, just as in China the musical wisdom of ancient times has fallen into neglect. Yet throughout the wide territories in which Mohammedanism established itself, that peculiar and distinctive type which more than any other represents Oriental music to us, a type resulting from a mixture of Persian and Arabian styles, complicated with Christian and other influences, has been traditionally handed down to the present day. As in the other systems we have discussed, harmony is practically non-existent. The scales are seven-toned and there are some eighteen theoretical modes. Both duple and triple rhythms are employed with greatest variety. In fact, one of the most striking characteristics of Mohammedan musical art is the variety and complexity of its sharp rhythms. The melodies are excessively adorned with every sort of flourish and ornament, slides, turns, grace-notes, shakes, and arabesques of every description not pleasing to our ears. Popular songs and professional musicians are to be found throughout all the Mohammedan Orient. The love song in particular is held in high esteem in all Mohammedan countries, and the following example may illustrate its charm:
