Voicing (music)

Various voicings: V/V-V-I progression.  1st ,[1] 2nd ,[2] 3rd ,[3] 4th , 5th [4] and 6th [5]

In music composition and arranging, a voicing is the instrumentation and vertical spacing and ordering of the pitches in a chord (which notes are on the top or in the middle, which ones are doubled, which octave each is in, and which instruments or voices perform each).

Voicing is "the manner in which one distributes, or spaces, notes and chords among the various instruments" and spacing or "simultaneous vertical placement of notes in relation to each other."[6]

For example, the following three chords are root-position C major triads voiced differently:

Close position  Play 
Open position  Play 
Open position, doubled fifth  Play 

All three voicings above are in root position, while the first is in close position, the most compact voicing, and the second and third are in open position, which includes wider spacing. In triadic chords, close root position voicing is the most compact voicing in thirds which has the root in the bass. Open and closed harmony are harmony and harmonization constructed from open and close position chords, respectively.

The Psalms chord is noted for its characteristic spacing of an E-minor triad.

Doubling

Octave doubling in John Philip Sousa's "Washington Post March", m. 1-7[7] Play .
Non-octave doubling in Debussy's Sarabande from Pour le Piano (For the Piano), m. 1-2[7] Play .

Melodic doubling in parallel is the addition of a rhythmically similar or exact melodic line or lines at a fixed interval above or below the melody to create parallel movement[8] while octave doubling (and doubling at other intervals, also called parallelism[7]) of a voice or pitch is a number of other voices duplicating the same part at the same pitch or at different octaves. The doubling number of an octave is the number of individual voices assigned to each pitch within the chord. For example, in the three images in the introduction above only one pitch is doubled, the G in the rightmost image (above).

J.S. Bach – "Gigue" from English Suite no. 1 in A Major, BWV 806, m. 38  Play .

Parallelism destroys, creates, or maintains independence of lines; for example, in deference to the practices of his day always requiring and desiring a degree of independence in all lines, in Bach's "Gigue" from his English Suite no. 1 in A Major, BWV 806, m. 38 note that neither thirds (at the beginning) nor sixths (at the end) are maintained throughout the entire measure, nor any interval for more than four consecutive notes, but rather that the bass line is given its own part.[7]

The Italian sixth moving to V.  Play  Note that the third of the first chord (tonic, C) is doubled.

Consideration of doubling is important when following voice leading rules and guidelines, for example when resolving to an augmented sixth chord never double either notes of the augmented sixth, while in resolving an Italian sixth it is preferable to double the tonic (third of the chord).[9]

Some pitch material may be described as autonomous doubling in which the part being doubled is not followed for more than a few measures often resulting in disjunct motion in the part that is doubling, for example, the trombone part in Mozart's Don Giovanni.[10]

Drop Voicings

One nomenclature for describing certain classes of voicings is the "drop-n" terminology, such as "drop-2 voicings", "drop-2-and-4 voicings", etc. (sometimes spelled without hyphens).

This systems views voicings as being built from the top down (probably from horn-section arranging where the melody is a given). The implicit, non-dropped, default voicing in this system is where all voices are in the same octave, with the individual voices being numbered from the top down. The highest voice is the first voice or voice 1. The second-highest voice is voice 2, etc. There is no provision in this nomenclature for having more than one voice on the same pitch.

A dropped voicing is where one or more voices are lowered by an octave relative to the default state. Dropping the first voice is undefined; a drop-1 voicing would still have all voices in the same octave and would result in a new first voice. There is no provision in this nomenclature for indicating the dropping of voices by two or more octaves or for having the same pitch represented in multiple octaves.

A drop-2 voicing is where the second voice is lowered by an octave. For example, a C triad has three "drop-2 voicings": reading down from the highest voice, C E G (the G has been dropped an octave), G C E, and E G C, which can be heard as the voicings supporting the first three melody notes of the Super Mario Bros. video game theme.

These are the drop-2-and-4 voicings for G7: (reading from the top down) G D F B (F and B have been dropped an octave), F B D G, D G B F, and B F G D.

Various drop combinations are possible, given enough voices, such as drop-3, drop-2-and-3, drop-5, drop-2-and-5, drop-3-and-5, etc.
