century. Instrumental music was also cultivated at the Burgundian courts, often for dancing. A peculiarity of the Burgundian instrumental style is that the dukes preferred music for loud instruments (trumpets, tambourins, shawms, bagpipes) and more of this survives than for other current instruments such as the lute or the harp. In contemporary practice, the loud instruments would usually play from an elevated location, such as a balcony, while the other instruments would play closer to the dancers. Instrumental forms included the basse danse, or bassadanza, which was a ceremonial dance of a rather dignified character, and relatively slow tempo. Typically it was in a duple meter subdivided into threes (in modern notation, 6/8), and often the dance would be immediately followed by a quick dance, the tordion or pas de Brabant. The Burgundian School was the first generation of what is sometimes known as the Netherlands School, several generations of composers spanning 150 years who composed in the polyphonic style associated with the mainstream of Renaissance practice. Later generations, which were no longer specifically associated with either the court or the region of Burgundy but were interlinked by adjacent geography and by common musical practice, included such names as Johannes Ockeghem, Jacob Obrecht, Josquin des Prez, Adrian Willaert and Orlandus Lassus. Manuscript sources There are approximately 65 manuscript sources which contain music by Burgundian composers. The most prominent of these include: Canonici Manuscript (containing music from around 1400 to 1440). This manuscript is at the Bodleian Library in Oxford, England; it is named after a previous owner, Matteo Luigi Canonici, an 18th-century Venetian Jesuit. It has 380 compositions in all, including works by 60 composers. Both sacred and secular music are well represented in this collection. Laborde Chansonnier (containing music mainly composed during the reign of Charles the Bold, 1467–1477). It is named after the Marquis de Laborde, and is presently at the Library of Congress in Washington, DC. It has 106 pieces of music in all. Mellon Chansonnier (containing music from approximately 1440 to 1477). It is named after Paul Mellon, who gave it to Yale University; currently it is in the Beinecke Library there. It has 57 compositions, and includes some non-Burgundian music as well (for example, works by contemporary English and Italian composers) Dijon Chansonnier (containing music from approximately 1470 to 1475). Some of the music is by composers not normally associated with the Burgundian school, such
