/foh"beuhr don'/; Fr. /foh boohrdd dawonn"/, n.

1. Music. a 15th-century compositional technique employing three voices, the upper and lower voices progressing an octave or a sixth apart while the middle voice extemporaneously doubles the upper part at a fourth below.

2. the use of progressions of parallel sixth chords.

(French), English  false bass , also called  faburden 

      musical texture prevalent during the late Middle Ages and early Renaissance, produced by three voices proceeding primarily in parallel motion in intervals corresponding to the first inversion of the triad. Only two of the three parts were notated, a plainchant melody together with the lowest voice a sixth below (as e below c′); occasional octaves (as c–c′) occurred as well. The middle part was realized by the singer at the interval of a fourth below the plainchant melody (as g below c′). The result was a particularly “sweet” sound in contrast to the mixture of passing dissonants and open sonorities favoured in earlier music.

      Guillaume Dufay (c. 1400–74) is said to have been the first to introduce fauxbourdon into written music. Other early 15th-century Burgundian and Netherlandish composers, too, embraced this essentially homophonic technique, especially for psalm and hymn settings requiring distinct textual articulation and clear enunciation. In more elaborate compositions the fauxbourdon texture appeared at times greatly varied and ornamented, as in several settings of the Magnificat by Gilles Binchois (died 1460). Fauxbourdon was, therefore, an important element in the transition from the medieval emphasis on perfect consonants to the euphony that characterized the a cappella polyphony of the Humanist era.

      At least one school of musical scholarship holds that fauxbourdon represents a continental adaptation of an English method of extemporaneous singing in which upper and lower voices were added to a chant melody to form ⁶/₃ chords. If so, it would seem that by the mid-15th century the designation fauxbourdon, anglicized to faburden, was being applied to the original practice. At any rate, English composers did favour successions of ⁶/₃ chords in any number of written compositions with the crucial melody in the middle or at the top and the rest often richly enhanced. This style of composition, too, is often called English descant, faburden, or fauxbourdon. In addition, English composers employed fauxbourdon in its continental form as well. It is now generally believed that English descant originally involved singing in two parts with an upper voice extemporaneously added to a plainchant, frequently in contrary motion, as opposed to the parallel motion typical of fauxbourdon.

      In 16th-century Italy and Spain, simple chord settings of psalms, usually in four parts, were frequently labelled falsobordone. But unlike the earlier fauxbourdon, falsobordone was based on chords in root position. Even though inversions do not necessarily alter the harmonic implications of chords, root positions do convey a greater sense of harmonic stability, since the fundamental tone, the chord root, appears in the bass, acoustically its natural habitat.

      Finally, in the 16th century, English keyboard music, too, was sometimes based on a cantus firmus, or underlying melody, called “faburden of the chant,” consisting not of the original plainchant but of its transposition to a lower pitch, as in the second voice of a fauxbourdon. “O Lux on the faburden” by John Redford (died 1547) is a well-known example based on such a derivative melody.
