The Renaissance period ushered in the rebirth and rediscovery of the arts such as music, painting, sculpture and poetry and also saw the beginnings of some scientific discoveries. The Baroque period saw a refinement of science and further advances in that field. These advances helped to pave the way for new inventions and, gradually, the improvement of medicine, mining, navigation, and industry.
Music history in the baroque period had many fine composers. Four of the best-known composers of the Baroque period are George Friedrich Handel, Johann Sebastian Bach, Antonio Vivaldi, and Claudio Monteverdi. The music written by these composers was largely on commission, meaning that composers were asked to write a certain piece for a specific location. The court of the aristocracy, churches, opera houses, and municipalities commissioned music. They employed musicians and required new music for each occasion. Composers of this period tended to use more homophonic texture in their music, one main melody accompanied by either other voices or instruments, in contrast to the polyphonic style of the Renaissance age. They stressed the contrast of sound, such a solo singers against a chorus or voices against instruments.
Music in the Baroque period also had several distinct characteristics. Unity of mood meant that a Baroque piece usually expressed one basic emotion. Rhythmic patterns that were heard at the beginning of the piece and repeated throughout the piece were referred to as unity of rhythm. An opening melody that was heard again and again in the course of the piece was called continuity of melody. Terraced dynamics meant that the volume tended to stay constant for a period of time, and that when the dynamics did shift, it was sudden, as if stepping from one dynamic level to another. Gradual changes in dynamics were not typical of Baroque music. The words and meanings for the words were depicted vividly in the music; this is called Word Painting. For example, the word heaven might be set to a high tone or notes moving upward and the word hell to a lower tone or a descending scale.
Also in the Baroque period, there were two very important developments in the use of musical groups. One was the beginning of the orchestra. The orchestra evolved into a performing group that was based on instruments from the violin family. Certain Woodwind and brass instruments were added as the Baroque period progressed. The other new form was opera. Up to the beginning of the Baroque period, opera had not existed. At the very beginning of the Baroque period, opera developed as an important art form. Perhaps the most important composer to help develop opera was a great composer named Claudio Monteverdi.
