Song is a piece of music for singing, either by a solo singer supported by instrumentalists or by a group consisting of a duo, trio or larger ensemble (larger classical vocal forms are termed aria and recitative). Speech and song have been combined from the earliest times; music heightens the effect of words by accentuating their projection and passion, and by giving them a resonance that is not possible with spoken language alone. The style of singing varies widely within and between cultures. Some value a relaxed, natural vocal quality, and others seek a highly trained sound with precisely articulated lyrics.
Generally, songs consist of lyrics and tunes, but there are many other aspects to a song. A well crafted song connects to a wide audience and causes them to react; it might make them cry, laugh, dance or tap their feet. Some songs become international hits, reaching the top of one or more charts. Then there are the mega-hits, the songs that have a global impact beyond the confines of any chart.
The Library has an extensive collection of resources on the subject of song, from individual essays that give the history of specific songs to broader topics such as American Popular Songs; Parlor and Concert Stage; and Traditional and Ethnic Songs. Some articles provide a different framework for studying song by examining themes, such as Social Change; Work and Industry; and Religion and Spirituality.
