Parry.—Evolution of the Art of Music, Chapter V. Barrett.—English Glee and Madrigal Writers. QUESTIONS AND SUGGESTIONS. Who was the most important of the earlier composers for the Church? Give a sketch of his life. What did he do for the music of the Church? What peculiarities marked his style? Give a brief résumé of the Council of Trent. (Consult a general history or church history.) What attempts at part music did the Minstrels make? Who took up this work later? What is the origin of the word Madrigal? Name some composers of Madrigals in Italy. In what other country did the Madrigal take hold? Name some of the composers in that country who cultivated the Madrigal style. Name some characteristics of the Madrigal. What influence did the Madrigal exert? Who invented printing music from movable types? If the members of the class cannot sing a madrigal or there is no choral society at hand that sings them, a string quartet can play the parts, or any combination of instruments that can represent the necessary four, five or six parts; two or four players at two pianos can give some idea. Novello & Co. publish in cheap octavo form many of the finest madrigals by the Italian and English composers. The members of the class should sing or follow the playing of each part of at least one madrigal and note its essentially melodic character. This class of compositions will also give an idea of the character of the old Church motet and the methods used in the masses. LESSON XV. MUSICAL INSTRUMENTS. =Classification of Instruments=.—The means for the production of musical sound are few in number, and of such universality and antiquity that we cannot say when, how, or by whom they were invented. Modern skill has not added one new means, but has simply improved the contrivances by which musical sound is produced. We can, however, trace the evolution and growth of the various instruments with considerable accuracy, and to this end it is of the utmost importance to have a clear understanding of the principles upon which musical instruments are constructed, in order to avoid bewilderment among the endless variety that have been and are yet made. All instruments may be divided into three general classes: Percussion Instruments, Wind Instruments, Stringed Instruments.
