An Italian
concerto relies upon the contrasting roles of different groups of instruments in an ensemble; Bach imitates this effect by creating contrasts using the
forte and
piano manuals of a two-manual
harpsichord throughout the piece.
Related works Along with the
French Overture and some of the
Goldberg Variations, this is one of the few works by Bach which specifically require a 2-manual harpsichord. However, it is not unusual in being a solo keyboard work based on Italian concertos. Long before the publication of the
Italian Concerto, Bach produced a number of
concerto transcriptions while working at Weimar. These are of music by
Vivaldi and others, reflecting the court's interest in Italian music. They are for harpsichord (BWV 972–987), and for
organ or
pedal harpsichord (BWV 592–596). ==Movements==
