Answer the following question: Information: - Opera buffa (plural: "opere buffe"; Italian for "comic opera") is a genre of opera. It was first used as an informal description of Italian comic operas variously classified by their authors as "commedia in musica", "commedia per musica", "dramma bernesco", "dramma comico", "divertimento giocoso". - 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. - Sonata (Italian: , pl. "sonate"; from Latin and Italian: "sonare", "to sound"), in music, literally means a piece "played" as opposed to a cantata (Latin and Italian "cantare", "to sing"), a piece "sung". The term evolved through the history of music, designating a variety of forms until the Classical era, when it took on increasing importance, and is vague. By the early 19th century, it came to represent a principle of composing large-scale works. It was applied to most instrumental genres and regardedalongside the fugueas one of two fundamental methods of organizing, interpreting and analyzing concert music. Though the musical style of sonatas has changed since the Classical era, most 20th- and 21st-century sonatas still maintain the same structure. - An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments. - In musical terminology, tempo ("time" in Italian; plural: "tempi" ) is the speed or pace of a given piece or subsection thereof, how fast or slow. Tempo is related to meter and is usually measured by beats per minute, with the beats being a division of the measures, though tempo is often indicated by terms which have acquired standard ranges of beats per minute or assumed by convention without indication. Tempo may be separated from articulation, or articulation may be indicated along with tempo, and tempo contributes to the overall texture. While the ability to hold a steady tempo is a desirable skill, tempo is changeable, and often indicated by a conductor or drummer. While practicing, an electronic or mechanical device, a metronome, may indicate the tempo, as one usually works one's way up to being able to perform at the proper tempo. In other words it is the speed at which a passage of music is or should be played. - 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. - A libretto is the text used in, or intended for, an extended musical work such as an opera, operetta, masque, oratorio, cantata or musical. The term "libretto" is also sometimes used to refer to the text of major liturgical works, such as the Mass, requiem and sacred cantata, or the story line of a ballet. - A bassline (also known as a bass line or bass part) is the term used in many styles of popular music, such as jazz, blues, funk, dub and electronic, or traditional music, for the low-pitched instrumental part or line played by a rhythm section instrument such as the electric bass, double bass, cello, tuba or keyboard (piano, Hammond organ, electric organ, or synthesizer). It is also used sometimes in classical music. In solo performance, basslines may simply be played in the lower register of any instrument such as guitar while melody and/or further accompaniment is provided in the middle or upper register. In solo music for piano and pipe organ, these instruments can be used to play a deep bassline. - Rhythm (from Greek , "rhythmos", "any regular recurring motion, symmetry" ) generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions" . This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years. - Ad libitum is Latin for "at one's pleasure"; it is often shortened to "ad lib" (as an adjective or adverb) or "ad-lib" (as a verb or noun). The roughly synonymous phrase "a bene placito" ("in accordance with [one's] good pleasure") is less common but, in its Italian form "a piacere", entered the musical "lingua franca" (see below). - Opera seria (plural: "opere serie"; usually called "dramma per musica" or "melodramma serio") is an Italian musical term which refers to the noble and "serious" style of Italian opera that predominated in Europe from the 1710s to c. 1770. The term itself was rarely used at the time and only attained common usage once "opera seria" was becoming unfashionable and beginning to be viewed as a historical genre. The popular rival to "opera seria" was "opera buffa," the 'comic' opera that took its cue from the improvisatory commedia dell'arte. - 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. - Theatre or theater is a collaborative form of fine art that uses live performers, typically actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek (theatron, "a place for viewing"), itself from (theaomai, "to see", "to watch", "to observe"). - 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. - Dramma per musica (Italian, literally: "drama for music", plural: "drammi per musica") is a term which was used by dramatists in Italy and elsewhere between the late-17th and mid-19th centuries. In modern times the same meaning of "drama for music" was conveyed through the Italian Greek-rooted word "melodramma" (from = song or music + = scenic action). "Dramma per musica" never meant "drama "through" music", let alone music drama. - An opera house is a theatre building used for opera performances that consists of a stage, an orchestra pit, audience seating, and backstage facilities for costumes and set building. While some venues are constructed specifically for operas, other opera houses are part of larger performing arts centers. - Melodramma (plural: "melodrammi") is a 17th-century Italian term for a text to be set as an opera, or the opera itself. In the 19th-century, it was used in a much narrower sense by English writers to discuss developments in the early Italian libretto, e.g., "Rigoletto" and "Un ballo in maschera". Characteristic are the influence of French bourgeois drama, female instead of male protagonists, and the practice of opening the action with a chorus. - A symphony is an extended musical composition in Western classical music, most often written by composers for orchestra. Although the term has had many meanings from its origins in the ancient Greek era, by the late 18th century the word had taken on the meaning common today: a work usually consisting of multiple distinct sections or movements, often four, with the first movement in sonata form. Symphonies are scored for string (violin, viola, cello and double bass), brass, woodwind, and percussion instruments which altogether number about 30100 musicians. Symphonies are notated in a musical score, which contains all the instrument parts. Orchestral musicians play from parts which contain just the notated music for their instrument. A small number of symphonies also contain vocal parts (e.g., Beethoven's Ninth Symphony). - Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows: European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity. - 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. - Art music (also known as Western classical music, cultivated music, serious music, canonic music, or more flippantly, "real music" and "normal music") is an umbrella term that refers to musical traditions, implying advanced structural and theoretical considerations and a written musical tradition. The main tradition in the Western world is usually called classical music. "Serious" or "cultivated" music are terms frequently used as a contrast for ordinary, everyday music (popular and folk music, also called "vernacular music"). After the 20th century, art music was divided into two extensions: "serious music" and "light music". - 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. - A concerto (from the , plural "concerti" or, often, the anglicised form "concertos") is a musical composition, whose characteristics have changed over time. In the 17th century, "sacred works for voices and orchestra were typically called concertos." J. S. Bach "was thus reflecting a long-standing tradition when he used the title 'concerto' for many of the works that we know as cantatas.". But in recent centuries, up to the present, a concerto is a piece usually composed in three parts or movements, in which (usually) one solo instrument (for instance, a piano, violin, cello or flute) is accompanied by an orchestra or concert band. - A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores). - 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. - Popular music is music with wide appeal that is typically distributed to large audiences through the music industry. These forms and styles can be enjoyed and performed by people with little or no musical training. It stands in contrast to both art music and traditional or "folk" music. Art music was historically disseminated through the performances of written music, although since the beginning of the recording industry, it is also disseminated through recordings. Traditional music forms such as early blues songs or hymns were passed along orally, or to smaller, local audiences. - 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. - Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove. - Italian opera is both the art of opera in Italy and opera in the Italian language. Opera was born in Italy around the year 1600 and Italian opera has continued to play a dominant role in the history of the form until the present day. Many famous operas in Italian were written by foreign composers, including Handel, Gluck and Mozart. Works by native Italian composers of the 19th and early 20th centuries, such as Rossini, Bellini, Donizetti, Verdi and Puccini, are amongst the most famous operas ever written and today are performed in opera houses across the world. - Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms". - This is an inclusive list of opera festivals and summer opera seasons , and music festivals which have opera productions .
