Complementary scales refer to the relationship between any series of tones selected from the twelve-tones and the other tones which are omitted from the series. They are discussed in Parts V and VI. This theory, which is perhaps the most important— and also the most radical— contribution of the text, is based on the fact that every combination of tones, from two-tone to six-tone, has its complementary scale composed of similar proportions of the same intervals.

of all of the possible sonorities contained in the twelve tones of

the equally tempered chromatic scale, in both their melodic and

harmonic implications, our

to explain the reasons for

Such chromatic tones are commonly analyzed

but the student will find

useful also to observe their

position in an "expanded" scale structure.

Study the thematic material of the Beethoven symphonies and determine

how many

projection.

A

useful device of

many contemporary composers

is

to begin

a passage with only a few tones of a particular projection and

then gradually to expand the

medium by adding more

tones of

the same projection. For example, the composer might begin a

phrase in the perfect-fifth projection by using only the

    the perfect-fifth-pentatonic scale C-D-E-G-A. Begin in the key of C, being careful to use only the five tones of the scale

    same scale on E (E-F#-G#-B-CJj:). Now moduon F# (F#-Gif-A#-C#-D#) and from F# to Eb (Eb-F-G-Bb-C). Now perform a combined modal and key modulation by going from the pentatonic scale on E^ to the pentatonic scale on B (B-C#-D#-F#-G#), but with G# as the key center. Conclude by modulating to the pentatonic scale on F, with D as the key center ( F-G-A-C-D ) and back to the original

    E— retains

    common tone. The second modulation, from E to F#, retains three common tones. The third, from F# to E^, has two common tones. The fourth, from E^ to B, like the first modulation, has only one common tone. The fifth, from B to F, has no common tones, and the sixth, from F to C, has four common tones. only one

    it

    will

    be seen that the six-tone major-third

    something of the same homogeneity of material that

    The

    is

    includes only the intervals of the perfect

    fifth,

    scale

    the major third,

    the minor third, and the minor second, or their inversions.

    does not contain either the major second or the tritone.

    however, a more striking scale than the whole-tone

    It

    scale, for

    It is,

    it

    contains a greater variety of material and varies in consonance

    from the consonant perfect

    The

    we

    fifth to

    six-tone major-third scale

    is

    the dissonant minor second.

    an isometric

    scale,

    because

    begin the scale CgDSiEgGiGJgB on B, and project

    reverse, the order of the intervals remains the same.

    Projection of the Tritone

    The student will have observed, in examining the five series which we have discussed, the strategic importance of the tritone. Three of the six-tone series have contained no tritones— the perfect-fifth,

    minor-second, and major-third series— while in the

    other two series, the major-second and minor-third series, the tritone

    is

    therefore, in judging the relative importance of the tritone in scale to multiply the

    number

    of tritones

    by two.

    In the whole-tone scale, for example, thirds, six is

    The

    'Maverick' Sonority

    The vertical projection

    of the

    minor third and major second

    forms a sonority which can be described only as a "maverick,"

    because

    it is

    the only sonority in

    twelve-tone scale which

    plementary

    scale. It

    complementary examine

    it

    is,

    not

    of the tonal material of the

    itself

    a part of

    its

    own comits own we should

    instead, a part of the "twin" of

    Because of

    its

    unique formation,

    carefully.

    In Example 47-1, line

    1 gives

    the tone

    and major second above and below

    it.

    forms the descending complementary

    C

    with the minor third

    The second

    scale,

    half of line 1

    beginning on

    G# and

    containing the remaining seven tones which are not a part of the original pentad, arranged both as a melodic scale and as

    two perfect fifths, two major seconds, and two minor secondsone above and one below the tone F#. In line la we follow the usual process of projecting upward from C the order of the complementary heptad, producing the scale CiC#iDiEbiEI::|3G2A— also arranged as two perfect fifths, two major seconds, and two minor seconds, one above and one below the tone D. We find, however, that the original pentad of line 1

    is

    not a part of

    its

    corresponding heptad (line la). There

    can therefore be no connecting hexads. Line 2 gives the tetrad CsDiE^eA with

    its

    octad, while line 2a forms the octad projection.

    give the tetrad CgEbeAiBb with

    its

    complementary Lines 3 and 3a

    octad projection. Lines 4 and

    4a form the projected octad of the tetrad CsDiE^^Bb, and lines 331

    t

    COMPLEMENTARY SCALES 5 and 5a form the projected octad of the tetrad CoDjAiBb. The tetrads in Hnes 2 and 3 will be seen to be involutions, one of the other. In the same way, the tetrads of lines 4 and 5 form involutions of each other.
