While some venues are constructed specifically for operas, other opera houses are part of larger performing arts centers. - A tradition is a belief or behavior passed down within a group or society with symbolic meaning or special significance with origins in the past. Common examples include holidays or impractical but socially meaningful clothes (like lawyers' wigs or military officers' spurs), but the idea has also been applied to social norms such as greetings. Traditions can persist and evolve for thousands of yearsthe word "tradition" itself derives from the Latin "tradere" or "traderer" literally meaning to transmit, to hand over, to give for safekeeping. While it is commonly assumed that traditions have ancient history, many traditions have been invented on purpose, whether that be political or cultural, over short periods of time. Various academic disciplines also use the word in a variety of ways. - An aria (plural: "arie" , or "arias" in common usage, diminutive form arietta or ariette) in music was originally any expressive melody, usually, but not always, performed by a singer. The term became used almost exclusively to describe a self-contained piece for one voice, with or without orchestral accompaniment, normally part of a larger work. The typical context for arias is opera, but vocal arias also feature in oratorios and cantatas, sharing features of the operatic arias of their periods. - A playwright, also known as a dramatist, is a person who writes plays. - Egon Hilbert ( 19 May 1899 -- 18 January 1968 ) was an Austrian opera / theatre director .

It is employed in a variety of disciplines including filmmaking, television production, theatre, sound recording and reproduction, live performance, sound art, post-production, radio and video game development. Sound design most commonly involves the manipulation of previously composed or recorded audio, such as sound effects and dialogue. In some instances it may also involve the composition or manipulation of audio to create a desired effect or mood. A sound designer is one who practices the art of sound design. - Stage combat is a specialised technique in theatre designed to create the illusion of physical combat without causing harm to the performers. It is employed in live stage plays as well as operatic and ballet productions. With the advent of cinema and television the term has widened to also include the choreography of filmed fighting sequences, as opposed to the earlier live performances on stage. It is closely related to the practice of stunts and is a common field of study for actors. Several actors famous for their stage fighting skills have backgrounds in dance or martial arts training. - Stagecraft is the technical aspect of theatrical, film, and video production. It includes constructing and rigging scenery, hanging and focusing of lighting, design and procurement of costumes, makeup, procurement of props, stage management, and recording and mixing of sound. Stagecraft is distinct from the wider umbrella term of scenography. Considered a technical rather than an artistic field, it is primarily the practical implementation of a designer's artistic vision. - A theatre director or stage director is a director/instructor in the theatre field who oversees and orchestrates the mounting of a theatre production (a play, an opera, a musical, or a devised piece of work) by unifying various endeavours and aspects of production. The director's function is to ensure the quality and completeness of theatre production and to lead the members of the creative team into realizing their artistic vision for it. The director therefore collaborates with a team of creative individuals and other staff, coordinating research, stagecraft, costume design, props, lighting design, acting, set design, stage combat, and sound design for the production. If the production he or she is mounting is a new piece of writing or a (new) translation of a play, the director may also work with the playwright or translator. In contemporary theatre, after the playwright, the director is generally the primary visionary, making decisions on the artistic concept and interpretation of the play and its staging. Different directors occupy different places of authority and responsibility, depending on the structure and philosophy of individual theatre companies. Directors use a wide variety of techniques, philosophies, and levels of collaboration. - Drama is the specific mode of fiction represented in performance. The term comes from a Greek word meaning "action" (Classical Greek: , "drama"), which is derived from "to do" (Classical Greek: , "drao"). The two masks associated with drama represent the traditional generic division between comedy and tragedy. They are symbols of the ancient Greek Muses, Thalia, and Melpomene. Thalia was the Muse of comedy (the laughing face), while Melpomene was the Muse of tragedy (the weeping face). Considered as a genre of poetry in general, the dramatic mode has been contrasted with the epic and the lyrical modes ever since Aristotle's "Poetics" (c. 335 BCE)the earliest work of dramatic theory. - A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet). Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion. - Opera (English plural: "operas"; Italian plural: "opere" ) is an art form in which singers and musicians perform a dramatic work combining text (libretto) and musical score, usually in a theatrical setting. In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. - Acting is an activity in which a story is told by means of its enactment by an actor or actress who adopts a characterin theatre, television, film, radio, or any other medium that makes use of the mimetic mode. - Recitative (also known by its Italian name "recitativo") is a style of delivery (much used in operas, oratorios, and cantatas) in which a singer is allowed to adopt the rhythms of ordinary speech. Recitative does not repeat lines as formally composed songs do. It resembles sung ordinary speech more than a formal musical composition. - Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin. - Costume is the distinctive style of dress of an individual or group that reflects their class, gender, profession, ethnicity, nationality, activity or epoch. - A musician (or instrumentalist) is a person who plays a musical instrument or is musically talented.
