[Q]: Information:  - 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).  - 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".   - Antonio Caldara (1670  28 December 1736) was an Italian Baroque composer.  - 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.  - 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.  - 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.  - Demofonte ( also Demofoonte ; Il Demofoonte ; Demofoonte , ré di Tracia ( King of Thrace ) ; Démophon ; Demophontes ; or Dirce , L'usurpatore innocente ( `` Dirce , The Innocent Usurper '' ) is an opera seria libretto by Metastasio . The libretto was first set by Antonio Caldara in 1733 , but remained popular throughout the eighteenth century and was set over seventy times .  - 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.    What entity does 'demofonte' has the relation 'original language of work' with?
