Prelude (music)

A prelude (Präludium or Vorspiel; praeludium; prélude; preludio) is a short piece of music, the form of which may vary from piece to piece. While, during the Baroque era, for example, it may have served as an introduction to succeeding movements of a work that were usually longer and more complex, it may also have been a stand-alone piece of work during the Romantic era. It generally features a small number of rhythmic and melodic motifs that recur through the piece. Stylistically, the prelude is improvisatory in nature. The term may also refer to an overture, particularly to those seen in an opera or an oratorio. The first preludes to be notated were organ pieces that were played to introduce church music, the earliest surviving examples being five brief praeambula in the Ileborgh Tablature of 1448. These were closely followed by freely composed preludes in an extemporary style for the lute and other Renaissance string instruments, which were originally used for warming up the fingers and checking the instrument's tuning and sound quality, as in a group of pieces by Joan Ambrosio Dalza published in 1508 under the heading tastar de corde (in Italian, literally, "testing of the strings"). Keyboard preludes started appearing in the 17th century in France: unmeasured preludes, in which the duration of each note is left to the performer, were used as introductory movements in harpsichord suites. Louis Couperin (c.1626–1661) was the first composer to embrace the genre, and harpsichord preludes were used until the first half of the 18th century by numerous composers including Jean-Henri d'Anglebert (1629–1691), Élisabeth Jacquet de la Guerre (1665–1729), François Couperin (1668–1733) and Jean-Philippe Rameau (1683–1764), whose very first printed piece (1706) was in this form. The last unmeasured preludes for harpsichord date from the 1720s. The development of the prelude in 17th century Germany led to a sectional form similar to keyboard toccatas by Johann Jakob Froberger or Girolamo Frescobaldi.
