If a person desires to deliver a discourse, it will prove more effectual after musical melodies. The ancient Greeks, as well as Persian philosophers, were in the habit of delivering their discourses in the following manner: -- First, playing a few musical melodies, and when their audience attained a certain receptivity thereby they would leave their instruments at once and begin their discourse. Among the most renowned musicians of Persia was one named Barbod, who, whenever a great question had been pleaded for at the court of the King, and the Ministry had failed to persuade the King, they would at once refer the matter to Barbod, whereupon he would go with his instrument to the court and play the most appropriate and touching music, the end being at once attained, because the King was immediately affected by the touching musical melodies, certain feelings of generosity would swell up in his heart, and he would give way. You may try this: If you have a great desire and wish to attain your end, try to do so on a large audience after a great solo has been rendered, but it must be on an audience on which music is effective, for there are some people who are like stones, and music cannot affect stones.
