The title of "music director" or "musical director" is used by many
symphony orchestras to designate the primary
conductor and artistic leader of the orchestra. The term "music director" is most common for orchestras in the United States. With European orchestras, the titles of "principal conductor" or "chief conductor" are more common, which designate the conductor who directs the majority of a given orchestra's concerts in a season. In
musical theatre and
opera, the music director is in charge of the overall musical performance, including ensuring that the cast knows the music thoroughly, supervising the musical interpretation of the performers and pit orchestra, and conducting the orchestra. The
artistic director refers to someone who directs a
musical ensemble and is the primary leader in the implementation of all artistic plans. In most countries the title is generally understood to be equivalent or interchangeable with that of
music director, and carries the corresponding responsibilities of directing (conducting or rehearsing) the ensemble, programming repertoire and performers, and (often) cultivating an artistic vision and often a long-term artistic strategy for the organization. The title and corresponding position is understood to be the highest level of artistic or musical decision-making inside the hierarchy of the organization, often working with an administrative counterpart such as an
Executive Director, managing director, or CEO. Some organizations, including some large orchestras, opt to have a primary conductor who reports to an artistic director in charge of long-range planning and artistic decision-making outside of that directly related to the rehearsal and performance process. The term "music director" or "musical director" became common in the United States in the middle of the 20th century, following an evolution of titles. Early leaders of orchestras were simply designated as the "conductor." In the 1920s and 1930s, the term musical director began to be used, in order to delineate the fact that the person in this position was doing much more than just conducting, and to differentiate them from guest conductors who simply led one particular program or concert.
George Szell, for instance, was appointed as "musical director" of the
Cleveland Orchestra in 1946, and his position was so named until his death in 1970. His successor,
Lorin Maazel, was given the title "music director." Other major American orchestras kept more current with the times and began using the simpler term in the 1950s and 1960s. The term can also refer to the person who directs a school band or heads the music program. ==Film and theatre==
