Passacaglia

The passacaglia (/pæsəˈkɑːliə/; Italian: [passaˈkaʎʎa]) is a musical form that originated in early seventeenth-century Spain and is still used today by composers. It is usually of a serious character and is typically based on a bass-ostinato and written in triple metre.

The term passacaglia (Spanish: pasacalle; French: passacaille; Italian: passacaglia, passacaglio, passagallo, passacagli, passacaglie) derives from the Spanish pasar (cross, pass) and calle (street). It originated in early 17th-century Spain as a strummed interlude between instrumentally accompanied dances or songs. Despite the form's Spanish roots (confirmed by references in Spanish literature of the period), the first written examples of passacaglias are found in an Italian source dated 1606. These pieces, as well as others from Italian sources from the beginning of the century, are simple, brief sequences of chords outlining a cadential formula.

The passacaglia was redefined in the late 1620s by Italian composer Girolamo Frescobaldi, who transformed it into a series of continuous variations over a bass (which itself may be varied). Later composers adopted this model, and by the nineteenth century the word came to mean a series of variations over an ostinato pattern, usually of a serious character. A similar form, the chaconne, was also first developed by Frescobaldi. The two genres are closely related, and since "composers often used the terms chaconne and passacaglia indiscriminately ... modern attempts to arrive at a clear distinction are arbitrary and historically unfounded".

In early scholarship, attempts to formally differentiate between the historical chaconne and passacaglia were made, but researchers often came to opposite conclusions. For example, Percy Goetschius held that the chaconne is usually based on a harmonic sequence with a recurring soprano melody, and the passacaglia was formed over a ground bass pattern, whereas Clarence Lucas defined the two forms in precisely the opposite way. More recently, however, some progress has been made toward making a useful distinction for the usage of the seventeenth and early eighteenth centuries, when some composers (notably Frescobaldi and François Couperin) deliberately mixed the two genres in the same composition.

The melodic pattern—usually four, six or eight (rarely seven) bars long—repeats without change through the duration of the piece, while the upper lines are varied freely, over the bass pattern serving as a harmonic anchor.

The seventeenth-century chaconne, as found in Frescobaldi's music, more often than not is in a major key, while the passacaglia is usually in a minor key. In eighteenth-century French practice, the passacaglia leans more strongly to the melodic basso ostinato, while the chaconne, "in a reversal of the [seventeenth-century] Italian practice, in various respects undergoes a freer treatment".

Some examples are the organ passacaglias of Johann Sebastian Bach, Dieterich Buxtehude, Johann Pachelbel, Sigfrid Karg-Elert, Johann Caspar Kerll, Daniel Gregory Mason, Georg Muffat, Gottlieb Muffat, Johann Kuhnau, Juan Bautista Cabanilles, Bernardo Pasquini, Max Reger, Ralph Vaughan Williams (Passacaglia on B–G–C, 1933), George Frideric Handel and Leo Sowerby.

Passacaglias for lute have been composed by figures such as Alessandro Piccinini, Giovanni Girolamo Kapsperger, Sylvius Leopold Weiss, Esaias Reusner, Count Logy, Robert de Visée, Jacques Bittner, Philipp Franz Lesage de Richée [fr], François Dufault, Jacques Gallot, Denis Gaultier, Ennemond Gaultier, and Roman Turovsky-Savchuk, a passacaglia for bandura by Julian Kytasty, and for baroque guitar by Paulo Galvão, Santiago de Murcia, Francisco Guerau, Gaspar Sanz, and Marcello Vitale.^{[citation needed]}
