Musical composition can refer to an original piece of music , either a song or an instrumental music piece , the structure of a musical piece , or the process of creating or writing a new song or piece of music . ___MASK40___ who create new compositions are called composers in classical music . In popular music and traditional music , the creators of new songs are usually called songwriters ; with songs , the person who writes new words for a song is the lyricist . " Composition " is the act or practice of creating a song or other piece of music . In many cultures , including Western classical music , the act of composing typically includes the creation of music notation , such as a sheet music " score ", which is then performed by the composer or by other instrumental musicians or singers . In popular music and traditional music , songwriting may involve the creation of a basic outline of the song , called the lead sheet , which sets out the melody , lyrics and chord progression . In classical music , orchestration ( choosing the instruments of a large music ensemble such as an orchestra which will play the different parts of music , such as the melody , accompaniment , countermelody , bassline and so on ) is typically done by the composer , but in musical theatre and in pop music , songwriters may hire an arranger to do the orchestration . In some cases , a pop or traditional songwriter may not use written notation at all , and instead compose the song in her mind and then play , sing and / or record it from memory . In jazz and popular music , notable sound recordings by influential performers are given the weight that written or printed scores play in classical music . Esperanto ( or ; in Esperanto : ) is a constructed international auxiliary language . It is the most widely spoken constructed language in the world . The Polish - Jewish ophthalmologist L . L . Zamenhof published the first book detailing Esperanto , "," on 26 July 1887 . The name of Esperanto derives from " ("" translates as " one who hopes "), the pseudonym under which Zamenhof published Unua Libro . ___MASK87___ (), usually credited as L . L . Zamenhof , was a Polish - Jewish medical doctor , inventor , and writer . He is most widely known for creating Esperanto , the most successful constructed language in the world . He grew up fascinated by the idea of a world without war and believed that this could happen with the help of a new international auxiliary language , which he first developed in 1873 while still in school . A national anthem ( also state anthem , national hymn , national song etc .) is generally a patriotic musical composition that evokes and eulogizes the history , traditions and struggles of its ___MASK40___ , recognized either by a nation ' s government as the official national song , or by convention through use by the ___MASK40___ . The majority of national anthems are either marches or hymns in style . The countries of Latin America tend towards more operatic pieces , while a handful of countries use a simple fanfare . An international auxiliary language ( sometimes abbreviated as IAL or auxlang ) or interlanguage is a language meant for communication between ___MASK40___ from different nations who do not share a ___MASK78___ first language . An auxiliary language is primarily a second language . An anthem is a musical composition of celebration , usually used as a symbol for a distinct group , particularly the national anthems of countries . Originally , and in music theory and religious contexts , it also refers more particularly to short sacred choral work and still more particularly to a specific form of Anglican church music . `` La Espero '' ( `` The Hope '' ) is a poem written by Polish - Jewish oculist and doctor L . L . Zamenhof ( 1859 -- 1917 ) , the initiator of the Esperanto language . The song is often used as the anthem of Esperanto , and is now usually sung to a triumphal march composed by Félicien Menu de Ménil in 1909 ( although there is an earlier , less martial tune created in 1891 by Claes Adelsköld , as well as a number of others less well - known ) . It is sometimes referred to as the hymn of the Esperanto movement . Some Esperantists object to the use of terms like `` hymn '' or `` anthem '' for La Espero , arguing that these terms have religious and nationalist overtones respectively . Incidentally the current day Israeli national anthem Hatikvah also translates to `` the hope '' and is based on a poem written in 1878 , first put to music in 1888 and adopted as the anthem of the Zionist movement in 1897 . Dr . Esperanto ' s International Language , usually referred to as Unua Libro , was the first publication to describe Esperanto , then called the International Language . It was first published in Russian on July 26 , 1887 in Warsaw , by Polish oculist L . L . Zamenhof . Over the next few years editions were published in Polish , Russian , Hebrew , French , German , and English . This booklet included the Lord ' s Prayer , some Bible verses , a letter , poetry , the sixteen rules of grammar and 900 roots of vocabulary . In the book Zamenhof declared , " an international language , like a national one , is ___MASK78___ property " and renounced all rights to the language , effectively putting it into the public domain . Zamenhof signed the work as " Doktoro Esperanto " ( Doctor One - Who - Hopes ). Those who learned the new language began to call it " Esperanto " after Zamenhof ' s pen name , and Esperanto soon became the official name of the language .
