A chorale is a type of musical composition typically written for a choir, often featuring four vocal parts: soprano, alto, tenor, and bass. It is commonly associated with Christian worship and is characterized by its harmonized melodies, which are easy to sing and remember. Chorales often serve as hymns in religious services, allowing congregations to participate in singing. The term "chorale" can also refer to a specific style of music developed during the Baroque period, particularly in the works of composers like Johann Sebastian Bach. In this context, chorales are often based on existing hymns and are used as themes in larger compositions, showcasing rich harmonies and intricate vocal arrangements.
