This article is about the musical composition. For a singing group (sometimes called chorale), see choir.
A chorale was originally a Lutheranhymn sung by the entire congregation. In casual modern usage, this term also includes classical settings of such hymns and works of a similar character.
Chorales tend to have simple and singable tunes, because they were originally intended to be sung by the congregation rather than a professional choir. They generally have rhyming words and are in a strophic form (with the same melody being used for different verses). Within a verse, most chorales follow the AAB pattern of melody that is known as the German Bar form.
Chorales were at first monophonic tunes (melody only). However, as early as 1524, Johann Walter published a book of these chorales arranged for four or five voice parts.
Today, many of the Lutheran chorales are familiar as hymns still used in Protestant churches, sung in four-voice harmony. Often the harmonizations are taken from the final sections of cantatas by Johann Sebastian Bach. The melodies of the chorales were only in a few instances composed by Bach; the large majority of melodies were based on chorales that were already familiar to his congregation.
Chorale tunes also appear in chorale preludes, pieces generally for organ designed to be played immediately before the chorale in worship. A chorale prelude includes the melody of the chorale, and adds other contrapuntal lines. One of the first composers to write chorale preludes was Samuel Scheidt. Bach's many chorale preludes are the best-known examples of the form. Later composers of the chorale prelude include Johannes Brahms and Max Reger.
Derived from his understanding of musical settings of liturgy and Bach's chorale preludes, the symphonies, masses and motets of Anton Bruckner make frequent use of the chorale as a compositional device, often in contrast to and combination with the fugue.
Chorales have been the subject of many different musical treatments, most but not all from the GermanBaroque. See chorale setting for a description and a list of all the different types of musical setting and transformation that this important liturgical form has undergone.
