A musician (or instrumentalist) is a person who plays a musical instrument or is musically talented. Anyone who composes, conducts, or performs music may also be referred to as a musician.
Musicians can specialize in any musical style, and some musicians play in a variety of different styles. Examples of a musician's possible skills include performing, conducting, singing, composing, arranging, and the orchestration of music.
In the Middle Ages, instrumental musicians performed with soft ensembles inside and loud instruments outdoors. Many European musicians of this time catered to the Roman Catholic Church, providing arrangements structured around Gregorian chant structure and Masses from church texts.
Renaissance musicians produced music that could be played during masses in churches and important chapels. Vocal pieces were in Latin—the language of church texts of the time—and typically were Church-polyphonic or "made up of several simultaneous melodies." By the end of the 16th century, however, patronage split among many areas: the Catholic Church, Protestant churches, royal courts, wealthy amateurs, and music printing—all provided income sources for composers.
The Baroque period (about 1600 to 1750) introduced heavy use of counterpoint and basso continuo characteristics. Vocal and instrumental “color” became more important compared to the Renaissance style of music, and emphasized much of the volume, texture and pace of each piece.
