such compositions considered collectively
A song is a vocal piece of music nearly always with words and accompaniment that expresses a human situation or emotion; no other musical genre has older roots or encompasses a wider repertoire of traditional sub-species. Folk songs evoke national characteristics yet can show a startling similarity of melody or rhythm, suggesting archetypes. The more sophisticated ‘art’ songs began with the chansons of medieval minstrels and reached a pinnacle in the 19th cent. Lieder of Schubert and Schumann — Amanda Holden
