Meaning of Fauxbourdon in Music

Fauxbourdon is a musical texture that was prevalent during the late Middle Ages and early Renaissance. It is characterized by three voices progressing primarily in parallel motion. The technique involves two voices, the upper and lower voices, progressing an octave or a sixth apart, while the middle voice doubles the upper part at a fourth below, often extemporaneously.

The earliest explicit example of fauxbourdon may be found in the manuscript I-BC Q15, compiled around 1435, which contains several examples, including one by composer Dufay dating probably to around 1430. Dufay's contribution to this collection contains the first actual use of the term "fauxbourdon".

Fauxbourdon can also refer to the use of progressions of parallel sixth chords. It is worth noting that fauxbourdon is related to the English technique called faburden, and the two practices may have evolved from each other.

In summary, fauxbourdon is a compositional technique that involves three voices progressing primarily in parallel motion, with the upper and lower voices progressing an octave or a sixth apart, while the middle voice doubles the upper part at a fourth below .

1. In plain song, this term implies simple three part harmony, the plain song being the top voice, and the two other voices each, respectively, a sixth and a fourth below the plain song. This practice may have evolved from the English faburden, or vice-versa.

2. Simple harmonization of plain song in four parts with no polyphonic elaboration.

3. In hymn singing, a fauxbourdon is a treble descant superimposed upon the melody sung by the congregation.

The earliest definitely datable example of fauxbourdon is in a motet by Dufay, Supremum est mortalibus, which was written for the treaty reconciling the differences between Pope Eugene IV and Sigismund, after which Sigismund was crowned as Holy Roman Emperor, which happened on 31 May 1433.

drone, French bourdon, in music, a sustained tone, usually rather low in pitch, providing a sonorous foundation for a melody or melodies sounding at a higher pitch level.

Introduction. A Bourdon gauge is a mechanical device used to measure and display pressure. The gauge can be used for measuring pressure in both gas and liquid state systems. The bourdon gauge may appear like one of the least interesting pieces of equipment out there, but it is still one of the most widely spread.

Bourdon gauge type The Bourdon gauge consists of a tube bent into a coil or an arc. As the pressure in the tube increases, the coil unwinds. A pointer connected to the end of the tube can be attached to a lever and a pointer calibrated to indicate pressure.

The Bourdon pressure gauge works by measuring the amount of change in a coiled or semicircular metal tube by a pressurized fluid inside. This is due to the principle that a flattened tube tends to regain its circular form when pressurized.

Bourdon tube pressure gauges Bourdon tube pressure gauges are used for the measurement of gauge pressures from 0.6 7,000 bar (8.7 101,526.4 psi). They are classified as mechanical pressure measuring instruments, and thus operate without any supply voltage.

The Bourdon gauge consists of a tube bent into a coil or an arc. As the pressure in the tube increases, the coil unwinds. A pointer connected to the end of the tube can be attached to a lever and a pointer calibrated to indicate pressure.

gauge pressure Bourdon gauge is used to measure gauge pressure. Bourdon gauges are available to cover a large range of pressures. Bourdon gauges are purely mechanical devices utilising the mechanical deformation of a flattened but bent tube that winds or unwinds depending on the pressure difference between the inside and the outside.

In 1849, the French engineer Eugène Bourdon patented the pressure-measuring device commonly known today as the Bourdon tube.

Three forms of Bourdon tube. (a) C-type; (b) spiral type; (c) helical type. C-type tubes are available for measuring pressures up to 6000 bar.
