Maestro (//; Italian: [maˈestro]) (from the Italian maestro, meaning "master" or "teacher") is an honorific title of respect. The term is most commonly used in the context of Western classical music and opera, in line with the ubiquitous use of Italian musical terms.
The word maestro is most often used in addressing or referring to conductors. Less frequently, one might refer to respected composers, performers, impresarios, and music teachers.[example needed] In the world of Italian opera, the term is also used for musicians who act as répétiteurs and assistant conductors during performances (maestro sostituto or maestro collaboratore). Even the prompter (maestro suggeritore) may be referred to by this title.
Usage outside music
By extension, it is used in English to designate a master in an artistic field, usually someone with strong knowledge who instructs others in the field, though the term may sometimes be conferred through sheer respect for an artist's works. The word is sometimes used in fine arts such as painting and sculpture, though their "master", as in Old Master, is far more common. Maestro is used in the sport of fencing, for a fencing instructor, and may be used in other sports to convey respect for an individual's skill.
Particularly influential U.S. Federal Reserve Chairmen are also called maestro.
