    specifywith considerableprecisionconventionalmeters and durations.For inthese scoresour currentwisdom andour knowledgeof the serialpermutationsbywhich the durationsarise ead us to assumethat the precisionof these dura-tions isquiteimportant o the structureof the piece.If, asI arguen thispaper,these durationsare not accuratelyperceptible n the absence of a traditionalmetrichierarchy, hen commonly-heldconceptionsof rhythmin this musicneed to be reassessedrom the bottom up.Performers reperhapsmost immediatelyawareof the disparitybetweenthe metricnotationsof such scores and theirsound, for they must learn themetricnotations n orderto playthe piece. I rememberquite vividly he scoresof hoursI spentin 1970 as a memberof the Da CapoChamberPlayers,earn-ing the violinpartandthen rehearsinghe ensembleof Babbitt'sCompositionforFour nstruments.Simply n order to playthe notes at the righttime, I had tolearn o hearmyown partas well as all the otherparts n the texture n a metricframework-the notated one. In effect,I had memorizedasilentclick-trackorthe piece-a click-trackagainstwhich the rhythms playedout theirjazzy syn-copationsandcrossrhythms. ndeed, "jazzy" seems the appropriateerm todescribehow I heard and playedthe rhythmsagainstthe silentmetricgrid. Imust haveratherthoroughly memorized that metricgrid, for if I listened tothe concerttapenot longafterperforminghe piece, I couldeasilyhear t auto-maticallyn the notated meter.But I can also rememberwell my surprisesome months laterwhen I lis-tened againto the tape. In the interim,I hadforgottenthe measure-by-meas-uremetric structureof the piece. And what had seemed to me in my daysoffamiliarity rhythmic-metric tructureof crystalline larityhad become thor-oughly opaque.Seeminglyerraticimpulsesdominatedthe soundscape.Did anaudience,anyaudience,hearonly this latterpieceand neverthe one that I hadstrivenso hardto perform?Now to be sure we allgo throughperiodswherewe get to know a pieceinconsiderabledetail followed by other periods lastingmonths, years,or evendecades,when we do not hearthatpiece. Forthe bulkof the tonalrepertoire,when we re-encounter he work we maywell havelost our detailedmemoryofit. But the experience, or me at least,has not meant that I findmyselfunableto orientmyselfin the work. Yet with the musicof Babbittandother twen-tieth-century cores I findthat experiencerecurringwith a frequency hat dis-turbs me.For that experienceraisesquestionsthat go to the heartof what we under-stand to be the rhythmic-metrictructureof this music.Does the piecethat Ihearone waywhileperformingt change tsverynaturewhen it crosses he pro-scenium?Does the piecethat I hearone waywhen I tape it changeits naturewhen passing hroughthe playback ystem?Are the metriccalculations f theperformeras unintelligibleand irrelevant o the listeneras some apiandancewould be in helpingus locate a particularwildflower in a meadow?Are therhythmic-serialomputationsof the theorist(orthe composeraswell) equally

But I raise hequestionshere becausemy recent work on rhythmand meter in tonal musicleadsme to believethat the answers o thesequestionsmaywell requirea thor-ough rethinkingof the natureof meter andrhythm n muchtwentieth-centurymusic.

    THE NATUREOFMETERI haveargued lsewhereabout the factors hatgiveriseto meter and to ourper-ceptionof meter.' That discussionpertainsdirectly o tonal music, but manypointsareextensible o nontonalmusicaswell. I willsummarize hat discussionhere,but without supportingargumentsoundin the citedsource,concentrat-ingon thosepointsrelevanto nontonalmusic.Meter is one form of accentuationn music. Accent is animpulsethatmarksoffapointof initiationn music. Accentuations rise rommanydifferentactorsand occur in a virtuallynfiniterangeof strengths.The impulsethat beginsanote createsan accent n relation o the sustainedportionof thatnote and thesustainedportionof theprecedingnote (orto thesilence hatprecedes henote).The beginningof a new pitchaftera repeatedpitchisaccentedn relation o therepetitions of the preceding pitch (pitch-changeccent).The impulse thatlaunchesarelativelyongerduration saccented n relation o the beginningof apreceding horterduration(thedurational ccent).The impulsethat articulatesthebeginningof amotive orpattern saccented n relation o the interiorof thatmotive(thepattern-beinningaccent)Thepointof achange nmelodiccontour saccented n relation o the melodic motion thatcontinues n one direction thecontourccent).The beginningof a textureof greaterdensity s accented thetex-turalaccent).The point of harmonicchangeis accented(the harmonic-changeaccent).And so forth.All of these typesof accent arecausedby an event occurring n the music.These typesof accent resonate n us as listenersby markingoff points in timedifferentiated rom those points that do not receive such impulses. Metricaccentsaresomewhatdifferent n nature,for metricaccentsnot only can butquite frequentlydo occur atpointsin time whereno accentualactor spresent.Once the meteris established,we perceivemetricaccentson silentdownbeatsand on beatsandbeat-subdivisionshat no eventarticulates.Formeteris apsy-chologicalphenomenon.It istheyardstickwherebywe locate he musical ventsof the piecein agridof time-points.Weperceivequitedifferently,orinstance,harmonicchangesthat anticipatea beat, that occuron a beat, and that occuraftera beat due to suspension.The gridof the metrichierarchy,n its role of

    EXAMPLE 2

    Becauseof the immediatepresenceof allthese nestedpulselevels,a listenerrapidlybuilds he frameof the metrichierarchyo that he or she canmeasureallthe musical ventsin relation o the multiple evelsof the metrichierarchy.Theopeningof Mozart'sFortiethprojectsarathercompletemetrichierarchy ecauseof the continuouspulseson so manylevels. In other tonalpassages, omelevelsmaybe presentby implicationonly. The quarter-noteevel at the openingofBeethoven'sFifth,forinstance, simpliedbythe quadruple roupingof eighthsbecausegroupingsof two arethe only possible evelthat can nest within four.But actualquarternotes in anydimensionbarelyoccurduringthe entirefirsttheme-groupof this work. And metricalambiguity,when it does arise n tonalmusic, virtuallyalwaysaffectsonly one or two levelsof the metrichierarchy,while the higheror lowerlevelsremainconstant.At all levelsof the metrichierarchy, ulsesdo not necessarilymarkoffequalunits in termsof clock time. Rather,pulsesmarkofffiunctionallyquivalntunitsof time. Werecognizeconstantpulsesevenwhen aperformer mploysrubato.In a ritardando r an accelerando,we do not hearfractionalportionsof a beatbeingadded to or subtracted rom the successivedurations,as in Example3b.Rather,we hearthe pulse itself slowing down so that successively onger orshorterdurations arefunctionallyequivalentto the precedingand followingpulses. In otherwords, we hear a ritardando s in Example3a, and not as inExample3b. In thissense,our notationalsystemdoes not insist thatdurationsbe equally ongwith a mechanicalprecision,but rather hatdurationsof some-whatdifferingengthsare heardasfunctionally quivalent ven whilewe recog-nize theirclock-timedifferences.

    Thus, even if there weregreater egularity f pulsesat several evels n thesepassages,anyperceived ense of meter would be relativelyweak andsubjecttobeingeasilyupset by conflictingaccentuations.But the rhythmicserializationthatgivesrise to the rhythmicvalues n this and other passagesprecludes uchregularity.The result s the absenceof ametrichierarchyn the sensethatsuchahierarchys projected by almostall tonal music.

    is a sense in which the impulses are not moored to a larger system ofmeasurement.This rhythmicsenseis akin to aspectsof the pitchstructuringn this piece.The variouspermutations, ranspositions,and inversionsof the combinatorialtrichords hatgiveriseto the derivedsets, the concentration n averyfew har-monic intervalswithin each sectionof the Composition,he agregates formed

    throughout by the combinatorial et segmentsin each of the four structuralvoices-all these areaudibleand form the substanceof pitch relations.But alltheserelationshipsxist without the yardstick f the gravitationalullof a tonicnote or sonority.The relationshipsloatin relation o eachother. Similarly, llthe rhythmicstructurings elateto one another,but not to the yardstick f ametrichierarchy.But there s a difference etweenhavingpitchrelationshipsunctioningwith-out a central onic andhavingrhythmic elationshipsunctioningwithout amet-richierarchy.Pitchesare discreteandidentifiablentities. Linearand harmonicintervalsmaintain heiridentitywhetheror not a tonic ispresent.And a givenpitchremains hatpitchwhen it recurs.But in the absenceof the yardstick f ametrichierarchy,we maynot be perceivingdurationsn the same manneras weperceive hem in musicwith a metrichierarchy.This leadsto the second ramification f nonmetricrhythmicstructure-themanner in which durationsareperceived.As discussedabove, in music thatprojectsametrichierarchywe measurelengthsof notesin termsof pulsesattheirmetric evel,not in termsof durationmeasuredbyclock time. I can conceiveofno model thatmight explainhow the mind couldmeasuredurationswith anydegreeof accuracy nd relate he lengthsof these durations ne to anotherwith-out apulseas a common denominatorof two ormore durations. n the absenceof a metrichierarchy,manyof the durationsof the piece,no matterhow metro-nomically heyareperformed,maynot be perceptiblen the mannerimpliedbytheirnotated duration.Reviewthe opening clarinetsolo of the Compositionor FourInstrumentsnExample . The durations rise rom a1,4, 3, 2 proportion,asdepictedover thescore n Example4. Butin order o perceive,say,the Dbin measure2 as half hedurationof the Ebin measure1, a listenerwould have to be maintaining six-teenth-note pulse throughout measures1 and 2. The lone opening B hardlyestablishes sixteenthpulse.And though alistenermust be aware hat after heensuingEb,the C and Db are eachshorter han theirprecedingnote, withoutdeciding(in advanceand apartfrom the impulsesin the music) to use a six-teenth-notepulse, he orshe would have no wayto measureexactlyhow muchshorterthese notes are. The sixteenth is the common denominatorof the Eb(foursixteenthslong)andthe C (threesixteenthslong).Or considerthe openingthreemeasuresof the Arieda Capo n Example5.The measure-longpulseis clear n measures1-2. But how could a listenereverknow to subdivide hatmeasure-long ulseinto twelfths(eighth riplets) o that

As soon as other conflictingpartsenteredthe score, such anotationhad to be abandoned n favorof anarbitrarymetricnotation so thatallpartscouldbe coordinatedn performance.SeeExample6, whichpresents heunison openingof the sixth movement fromMessiaen'sQuatuorpourafin dutemps ndan earlierappearance f the same tune in an ensembletexture n thefourthmovement.Themetricallyreenotationof thesixthmovement isfineforensembleperformance.But the violinistand cellistmust also learn he tune instrict2/4 in orderto staywith the clarinetistn movement 4. Imagine rying operform he passage rom movement 4 wereit notated as in Example7. Nev-ertheless,t ismyexperiencehatthemelodyis heardbylisteners hesameway nmovements 4 and 6-that is, the listenerprobablyhears he fourth-movementpassage sin Example7.

    In conclusion,I believethatrhythmicnotationsof the Babbittcompositionsand of manyothertwentieth-centuryworkscannotreliablybe consideredaccu-raterepresentationsf the perceivedmetricstructureof thismusic,andcannotnecessarily e consideredaccuraterepresentationsf the perceiveddurationsofindividual ones.
