Certaincomposersmake more use of thesesounds thanothersdo. Someof the works by composerssuchas SergeiRachmaninofT, Gian Carlo Menotti, and Aaron Copland,for example,might be expectedto containa high proportion of triadsand 7th chords.whereasother composers,suchas Paul Hindemith,tend to reserve the pure soundof a triad for importantcadencesor even for the end of a movement.Still othercomposersrarely make use of thesemore traditionalsounds.Examplesof the use of triads and 7th chords will be found in later chaDters.where voice leadine and harmonic progressionare discussed. Tertian sonorities"taller" than the 7th chord-9th chords. 1lth chords. and 13th chords-are not an inrportantpart of tlre harmonicvocabularybefbrethe late nineteenthor earlytwentiethcentury.In theory,any diatonic triad can be extendedto a I 3th chord befbre its root is duplicated(seeExample 3-1). In practice,however,it is the dominant and secondarydominantchords,and to a lesserextentthe supertonicand submediantchords,that tendto be singledout for this treatment.Chromaticalterations,especiallyof chordswith a dominantfunction, are often used.Example3-2 illustratessomeof the possibilities.

I Ninths and other tall chords can be inverted,of course,but inversionscan be problematical, as we just saw with the iirI chord in Example 3-3. Refening back to Example 3-l , noticethat the pitch-classcontent ofevery diatonic l3th chord is identical, meaning that every diatonic 13th chord could be analyzedas an inversion of every other diatonic 13th chord.

A typically ambiguousexampleis seenin Example 3-5. The excerptbeginswith a tonic triad in D major, but the next chord is open to some interpretation (remember to include the flute part in your analysis).The pitch classes,in alphabeticalorder,are A, C, D' Et, F#, G. Bassnotesusually want to be roots,if they can,and the high D in the flute on the fourth beat reinforces the notion that this might be some sort of G chord. On the other hand, the G could be the I lth of a completeD 1lth chord: D-Ffi-A-C-Et-G, and the 45 to D6 in the flute seemsto support that. Or perhapsit should be analyzedas a D 9th chord presentedsimultaneouslywith G, its note of resolution.The uncertaintyis not resolvedby the Bb major 7th chord that follows, sinceneitherG-Bb nor D-Bb seemsparticularlycompelling as a progression.The remainder of the excerpt is more straightforward: A minor 7th to D minor 7th in m. 3, both slightly ornamented,to a more lavishly ornamentedG maior triad in m. 4.

QUARTAL AND QUINTAL CHORDS Composersof the twentieth century havenot restrictedthemselvesto tertian sonorities-that is, to chordal formations basedon stacked3rds. There are essentiallyonly four possibilities: Chordsbuilt from 2nds (7ths) Chordsbuilt from 3rds (6ths) Chordsbuilt from 4ths (5ths) Chords built from mixed intervals In this sectionwe will explorequartaland quintal chords-those built from 4ths and 5ths. Later sectionswill deal with chords constructedfrom 2nds and with mixed-interval chords. A quartal chord canhave as few as three pitch classes(as in Example 3-l7a) or it can have several (Example 3-l7b). It is sometimespossible to omit a member of a quartal or quintal chord (the E4 in Example 3-17b, for instance)without losing its character.Various 56 The VerticalDimension:Chords and Simultaneities voicings and octaveduplicationsare also used (as in Example 3-l7c), but some arrangementscould destroythe quartalcharacterof the sonority.Quintal chordswork the sameway (as in Example3-17c1),butthey havea more open and stablesoundand,of course,occupy more vertical spaceper chord member.Surely a near-recordfor rangemust be held by the ten-notequintal chord that occursnear the end clf GycirgyLigeti's Melodiesfor Orchestrd (1971),spanninga rangeof morethanfive octaves,fionr Abl to 86.

Example 3-22a containsone o4, while Example 3-22b contains two of them. As long as the voicing is predominantlyquartal,as it is here, it is probably correct to analyzeboth chords as altered 6 X 4 chords, but other voicings might lead to other analyses.The diminished scale can serve as the source for the chord in Example 3-22b.If you turn back to Example2-17 , you will seethat this chord is strongly suggested in varioustranspositionsand voicingsin that excerpt.

We haveanalyzed the chordsin this excerptas secundalchords,as mixed-intervalchords,and as l3th chords; we can see now that they are also whole-tone chords, each one being derived from one of the two whole-tonescales. POLYCHORDS A polychord combines two or more chords into a more complex sonority, but it is crucial that the listener be able to perceive that separateharmonic entities are being juxtaposed if the result is to be a true polychord.Any I lth or 13thchord could be explainedas a combination of two simpler sonorities,but this would be an incorrectanalysisif we do not hear them that way. EXAMPLE 3-30 ApparentPolychords In order to be heardas a polychord,the individual sonoritiesthat make up the polychord must be separatedby some meanssuch as registeror timbre. In Example 3-3 I the first and last chordscould easily be heardas I I th chords,but in the rest of the phrasethe different registersand the pervading contrary motion between the two chordal units result in an unambiguouspolychordal texture.Persichetticoncludesanotherof his works, the Symphony fbr Band, Op.69 (1956), with a spectacularpolychord that combines four registrally distinct sonorities:Bb major, A major 7th, B major 7th, and F major with an added9th.

The only requirement for a polychord is that the listener be able to perceive the chords as separateentities.There will inevitably be ambiguouscases,however,where one listener hearsa polychord and anotherhearsa single complex sonority. The use of a polychord does not necessarilyindicate that a passageis polytonal. Polytonalitywill be discussedin more detail in Chapter5. The VerticalDimension:Chords and Simultaneities SUMMARY The harmoniesof tonal music were limited for the nrostpart to tertiantriads and 7th chords.In contrast,composersof the twentiethcenturyhavef-eltfree to make use of any conceivablecombination of pitches.In the most sirnple terms, there are four possibilitiesfor chord construction: Secundalchords(alsotone clusters) Tertianchords(including gths,etc.) Quartalchords(also quintal chords) Mixed-intervalchords Tertian chords,the most traditionirl of the four types,have been subjectedto some new variations: Added notes Split chord members Open 5ths One specialcase,especiallyimportantin the early part of the century: Whole-tonechords And finally. the possibility of juxtaposing two or more aurally distinguishable sonorities: Polychords It is liequently the case that a particular sonority is open to more than one interpretation.This is particularly true with mixed-intervalclrords,many of which can be arrangedto resemblesecundal,tertian,or quarlalchords.The studentmust be sensitiveto the context and the voicing in attemptingto choosethe best analytical approach.The three chords in Example 3-33, though containing the same pitch classes,obviously must be analyzeddifferently.

Another approach to chords with added notes and split chord members is taken by Bryan Simms in Music of the TwentiethCentury,pp. 55-58. He identifiesnine pairsof "triadic tetrachords"-that is, four-note chords that contain a major or minor triad. The first chord of eachpair is a major triad plus one of the other nine notes of the chromatic scale,while the secondchord of each pair is the mirror inversion of the first. 2. Some writers use the term compound chord. 3. Some theoristsuse the term whole-tonedominant for whole-tonechords that have a traditional dominant function. EXERC'SES PortA: Fundamentals l. Review the nine chord types in the Summary section.Then find one example of each type in the example below. 2. Make up one example of each of the nine chord types and notate them on staff paper.
