The pleasure derived from music arises from its exciting agreeable sensations, and creating pleasing mental images and emotions. Apart from words, it expresses passion and sentiment; joined to words it becomes a beautiful illustration of language. From the earliest ages of the world music was held in high esteem, and in Egypt and Greece was considered an essential part of the religion of these ancient nations. God's greatest gift for man's pleasure is the hearing of sweet sounds. He gives us music in songs of the birds and there is such a variety of these aeriel musicians. In Paraguay, South America, is a bird called the "bell." When traveling through the forest one hears it at early morning, at mid-day and in the evening. So wonderfully like a bell is the note of this bird that on hearing its clear ring at regular intervals, one would suppose he were listening to the Angelus-bell from the tower of some church or monastery.
