A musician (Greek: μουσική [τέχνη]; Latin: mūsicus) is a person who plays a musical instrument. Anyone who composes, directs, or performs music is called a musician. A musician who plays a musical instrument is also known as a performer or instrumentalist.
Musicians can specialize in any style of music, and some play a variety of different styles depending on their culture and background. Some examples of the multiple activities that a musician can develop include interpretation, direction, singing, musical improvisation, composition, arrangements, orchestration and musical production.
They are those musicians who have formal music studies, in musical conservatories, music study centers, universities, institutes or academies, in order to perform as:
Instrumentalists (pianists, violinists, cellists, double bass players, percussionists, classical guitarists, etc.)
Music critic (not understanding entertainment and entertainment journalists)
They are those musicians who, not having formal music studies, interpret and compose in a self-taught way. Sometimes they are called amateur musicians, although they should not be confused with those musicians who, although they have training, perform their music on an honorary or amateur basis, that is, without receiving any economic benefit in return. Many of the empirical musicians play an instrument as a means of subsistence.
For Catholics, Santa Cecilia is the patron saint of music, according to a bull of Pope Gregory XIII of 1594. The patronal feast is celebrated on November 22, the date of the death of the martyr, which became the date to celebrate Musician's Day.
