An explanation was mede .of' the importance of a clear understanding of pressure, placement, and regard for individual differences in relation to the embouchure and mouthpiece. Answers to the following questions were soughtt (l) What may a mouthpiece be e.xpected to contri• bute toward good performance? (2) What mouthpiece for which player? (3) Under what conditions should a change of mouthpiece be recommended? The factor of tone prodUc­ tion• together with such ram1f'ica tions es .reaenanee 1 breath control. and vibrato was reviewed 1n ai!lbhor1tative so'Ul'eell and summarized.

It was not the writer's objective to invent or to propose any step by step plan of presentation of trombone technique as 1s commonly found in trombone method books, but to present a review of the factual information that 1s. essential 1n any flexible procedure or methodolo.gv. The investigator used analytical and observational researoh 4 methods. Related literature was extracted from method books and from literature concerning the teaching of brass instruments and the trombone• The investigator ueed certain observetional p1•actices with beginning in• strumental students at Texas State College for Women.

Review of Related Ma t erial The investigator has made an extensive search of studi e s 1n music and has been unable to discover com­ prehensive pedagogical mate-r ial concerning th, funda .. mentals o f trombone playing . Numerous pedagogical pre­ sentations concerning the trombone in respect to its relationship to other brass instruments and a few spe­ cific remarks as to its unique position in the brass family were found.

S:tn ce an unde rstanding o f' the harmonic s eries and its implications in r elati on to trombone s lide mechanism based on scientif ic information was deemed necessary f or setting up pedagogical concepts relat i ng t o the playing of the t enor trombone, a c omprehensive examination of harmonic overtones, int ona t i on problems , and a coustical considerations was made.

Harmonic Overtones

Almost every sound we he ar is a combina tion of tones of diff erent pitches. This complex s ound is made up of a series of tones consisting of a fundamental note plus its overtones or harmonics; the overtones or har­ monica are subliminal tones• This .fundamental note la called the P1rst partial, the first overtone of the f undamental is the s ecc:,nd partial, etc. P.i gure 1 shows the fundamental note BBb and its first eleven har monic overtones; pedal tone BBb is the fundamental note in f irst position of the tenor trombone• The t enor trombone has one fundamentsl note f or each of the seven slide positions. All of these notes are pedal . tones. In the trombone all tones are overtones of the fun­ damental tone of the pipe position in use at the time•

Intonation Problema BJ virtue of' cont1nu.ed exposure to keyboard in• atruments, we rney become tndo ctrinated. to piano tuning, the Equal Tempered ecale. Assuming tha.t our reflexes •re eond1 t1oned to the Equal Tempered see le, the overtone series or Just tun~ng, when need with music typically eight• eenth and nineteenth century in 1 t~ or1giri, sounds out or tune to ol.U." eare, As a result of this con.t'liet of tuning,

1natruments p:roduc1ng tones that are overtones of a funda• mental note of the overtone series, will have inherent 1nton£tt1on problems. An 1ntent1onally variable intonation 1n trombone playing 1111 desirable. The hand slide makH the trombone more eapabb or tledble 1ntQnet1on than any other b:rast 1n111trument. The perfol'!ller 1ntentionall:v uses deviat1ens 1n licale tones and slide po81tions in an effort to get 12 lil'll'!!y trm keyboard tun1ng. Seale patterns are relative rather than absolute. It is neither ne cessary nor ad• visable to adhere strictly to O);)e fixe d sosle pattern. Intonation should be flexible e. nd not a h111rd, .fast phy.. steel quantity• The prevale.nt scale pattern ehoiees available to present day trombone perf ormers are the Pythagorean, Just, e.nd Equal Tempered scele systems. 4 High intervals are charseter1st1c of the Pythagorean scaleJ llere,. sharps are higher than enharmonic f lats. Vitality is inherent in Pythagorean intonation. Low intervals are eharacteristic of the Just seeleJ here ., smrps lilre lower than enharmonic nata. Purity is characteristic of' Just intonation. The Equal Tempered scale divides the octave inte twelve equal semitones, aa used 1n keybOGrd tuning• Th.is seale takes a middle pesition between the Pythagorean and Just scale patterns, end some feel a loss 1n vitality of sound a.Tid a resulting drabness of the contrasts of major and mlnol" modes 1n temperf!d tuni~ • The trombone ls 1n a free posi• t1on to meet the demands of any of the scale patterns by minute a.djuatment ot' the slide position.

The distance between slide pos1~ tions becomes gr eat er as a minor c ompensating device for the more rapidly increasing length of the instrument. When the trombone 1s placed in a musical circumstance demandinc the use of e ither the Equal Tempered Scale or the Pythagorean intervals, the notes of the f ifth partial are excessively f lat. Altering offensive notes leads to com•

plications: when . one note 1.s changed through construction

of the instrument, lt is at the expense of rei'rnlting changes in other t ones . Correction of tho flat f ifth partial usually sharpens the notes o f the sixth pa1,t1al. A f lat d1, f i f th partial in f i r st pos ;_tion, cannot be altered by shortening the f irst slide position, but a sborp f1, sixth partial in first position, can easily be altered by a slight lengthen• ing of the f irst slide pos itionJ thoret'ore, sharpness of' the sixth partial may be considered less undesirable to the trombonist than flatness of the fifth partial., •rhis correc­ tion results in a slightly extended position of the trombone slide for the sixth partial. All seventh partial tones are inherently flat 1n relation to the Equal Tempered scale EJnd the Pythagorean

system. Method bod,a widely acknowledge the necessity of alterations o r the normal position for this partial, The

seventh partial in first position, A•flat1 , is unusebleJ the other notes of the seventh partial are played very short but 17 progres ,·1vely longer all J;he sli de 1a extended to its full lengths eecond position g1 . thir d position f #l, fourtll pos ition f1, and fifth position e1 are extremely ,short.

Figure 5 . Alternat & or Hi l se Slide Positions 18 In F1gure 5, parentheses about a position indicates that it h a false positlon, a position not generally used• The use of alternate or false pos1t1one i s the means by which a number of the trombonist 1 s execution difficulties may be solved. In first position, variable intonation is limited; pitch can be lowered by minute slide adjustments but not raiaede The only other ava.ilable option taken by some performers to make pitch raising adjustment possible in f irst position is t o tune the basic b-f lat to a slightly extended f irst position with a ll other posi tions extended accordingly. Alterna t e sli de positions me y be desirable f or the tones timt ere "lot when played in first position. In rapid passages an awkward slide movement can be prevented by the use o f' sn alternate position; f or instance , in a- line going from t 1 , f irst position, to f#l' fifth position, the r1 can be played in an alternste sixth position. Ordinarily, tones played in f i r st positions are more resonant and require iass projection of breath msking desir• able tone quality more easily produced than tones produced with the slide extended to another position and thereby length• ening the tubing of the instrument. The location of a tone in the harmonic series influences the playerts choice of slide positions. The lower the partial in the harmonic series the greater the number of overtones present thus enhancing the tone q:ua 11 ty • Notes in different slide positions can not hove an identical quality since the notes will not have the same 'loe.11\iti-Q-n in tho bll'Utori:Le a,e~S.ee • fbc, trOl'lil,on1tt aboul.i:! , ~M a.gt\J.aitt. ucivel'>P~&i a ~entfll bl.eek o.r t'ibiar ~t .t'lll.la• podt1cne, 'rbe tr!!!lllb~& play.;r ,itbo\lld WOll'k to dtvolop rue:oruint tione qu!ll;tty 11,nlil e;®'d tutoruition 11:1 &l.t.ei-nate ,.ostti".lrie »-iii ~ll u :tn N:GJ.llnr z;,9ett:1ono., Too 1.u:~ of' 11lt~rMte p

All trombones should be built in tune, A•440 when the tuning slide is extended to a moderate degree in order to permit rahing the pitch of the horn above A-440 by the use or the tuning sl:!:de. Changing the proportions o f the instrument by an extreme extension o r the tuning slide can a ffect the entire partial system making good intonation and tonal response almost impossible•

Acousti~l Considerations It 1s dif ficult to establish acoustical laws in trombone construction as the instrument 1s ne1!:;her wholly con~cal nor cylindrical. This leek of uniform;i..ty of taper 11 flare of the bell, and some corrections t'or the fifth pa,r .. t1al il&.ueea conflicts with the acoustical laws of open and closed pipes. Brass-wind instruments are assumed to produce 22 the same tones ae an _open pipe, that 1s, to produce all even and odd partials within a certs in limit. Follow1 ng

the laws o.f acoustics, a ciosed conical plpe produces- the same harmonic series es open pipes• The trombone is not conical in the true sense of the word; the cylindrical tu.be, expending into a bell by a line o f.' lncreeaing cur.. vature, gives an approximately hyperbolic shape.

In a perfeotly cylindrloal instrmnent the .nodes nnd sntinodes would be equally divided in length. The conical bore varies the positions of tho nodes and an tinodes J the nodes and antinodee no longer lie neatly and \,evei'lly spaced; ::JUt the unite are longer in the small part of the bore and shorter in the large part of the bore, This mak·es the appl1ca t1on of the principle for the correction of partials more complicated. Where each node or antinode will tall within the instrument t -ublng is ll;lore difficult to dEiterm1ne: no correction of a given overtone la possible until the exact location of each node and ant1node of that overtone is determined. Over-correction of 1-ntonation may cause und&s!N.ble blowing or sounding features of an instrument. CHAPTER rn ENIBOUCHUP.E AND THE MOUTHPIECE

Selection of a suitable mouthpiece is one o f the most common problems of brass players. The shape of the mouthp:l.ece exerts an 1mport,ant and, so far , unexpla i ned i nfluence on the tone; in the generation of t one the width of' the rim, width and depth o f cup,throat and bore o f shank, and the shape of the mouthpiece are con sidered impor tant. Th,~ construction of the mouthpie ce a f fects

A sharp edge on the inside o f the cupwrim provides a firm grip emibl­ ing the plll ye1• to better judge what tone he is g oing to play ; the edge determines the lip ·ribration at a f ixed point.

In the development oi' the embouchure~ bunching the lips is recommended in order to take f ull advantage of the muscle strength and lip flexibility so necessary in good trombone performance. (2) Resonance determines the quality and carry­ ing pow~r of every t one . The r e sonant quality is affected by the placement of the tongue within the mouth as well as by the structure quality of the instrument played. Re­ sonance is established in the head i:SV:!.ty ~ The openings of the throat, nose, mouth, and mouthpiece modify the qua lity of sound.

(3) Variable lntona tion on the tromb one, or :;;ny \ o ther brass instrumc, nt, is desirable in musical perf ormance. , The scale pattern in use and the scale degree o f the note determines the pitch. The i dea of pre~d~termined slide positions conflicts with the attempt to achieve variable intonotion. The trombonist should overcome the conscious mechanical aspects of performance and be trained to listen to make the tones fit in a given musical situation. 89 ( 4) 'i'h'6 ave1'83e loffllr teeth recede. behind the upper teeth4 J\py attmipt on the part of th.i pedagog to have the atudel'it koep tbe trombone 11parellol to tbe floor" would dbtort the Mrmal, relat1onsh1p ct the i;pper end lowo:r Jaw-.
