In this research, we used ul- trasound images for comparison of the tongue shapes. MATLAB and other software was also used for detailed measurements, and our results show that the tongue shape when playing clarinet is similar to Japanese “e”, the tongue shape when playing trumpet is similar to Japanese “o”. 1 Introduction Surprisingly, the wind instrument tonguing advice given by professional musicians and music teachers varies widely for clarinet (see Table 1) and trumpet (see Table 2). Since dierent teachers recommend making dierent vowel tongue shapes while playing, we decided to view the tongue directly, using ultrasound, to see what shape is made while playing. This research is a collaboration between the University of Aizu’s CLR Phonetics Lab and Professor Masaichi Takeuchi of Nagoya University of Arts. We believe that these results will be very useful for musicians who are teaching and learning to play clar- inet and trumpet. We are aware of only one other study that has been done looking directly at the tongue during the playing of a wind instrument [5], but in that study only clarinet tonguing was analyzed. # Research Study/Article Advice Given 1 Fritz et al.(2003) Lower register /æ/ Higer register /i/ 2 Fritz & Wolfe (2005) /i:/ 3 West (2001) /i:/ or /E:/ 4 West (2006) /i:/ 5 Gardner & Stone (2010) For register 2 /u/ and /E/ For register 3 /i/ For registers 4-5 /A/ Table 1: Published advice/ndings on what vowel to pro- duce when playing clarinet # Research Study/Article Advice Given 1 Saunders (2009) /A:/, not /i:/ 2 reversedlead (2010) Lower register /A:/ Higher register /y/ Table 2: Published advice on what vowel to produce when playing trumpet # Register 1 D3 - A at4 (147 - 415 Hz) 2 A4 - B at5 (440 - 932 Hz) 3 B5 - E6 (988 - 1319 Hz) 4 F6 - A at6 (1397 - 1661 Hz) 5 A6 - B at6 (1760 - 1865 Hz) Table 3: Explanation of register for both instruments 2 Method 2.1 Participants We collected data from Prof. Masaichi Takeuchi (pro- fessor of music and professional clarinet player) and Mr. Hitoshi Sugie (graduate music student and trumpet player) of Nagoya University of Arts. 2.2 Apparatus We used an ultrasound machine and special helmet to hold an ultrasound probe to record tongue movements when the trumpet player and clarinet player were play- ing and speaking (see Table 4 for details of the hardware used).

Wind instrument tonguing: Comparison of tongueshape during performance and speakingAsahi Suzuki s1150120 Supervised by Prof. Ian WilsonAbstractThis paper describes the relationship between the tongueshape when playing wind instruments (specifically clar-inet and trumpet) and the tongue shape when speakingthe five Japanese vowels. In this research, we used ul-trasound images for comparison of the tongue shapes.MATLAB and other software was also used for detailedmeasurements, and our results show that the tongueshape when playing clarinet is similar to Japanese “e”,the tongue shape when playing trumpet is similar toJapanese “o”.

1 IntroductionSurprisingly, the wind instrument tonguing advice givenby professional musicians and music teachers varieswidely for clarinet (see Table 1) and trumpet (see Table2). Since di!erent teachers recommendmaking di!erentvowel tongue shapes while playing, we decided to viewthe tongue directly, using ultrasound, to see what shapeis made while playing. This research is a collaborationbetween the University of Aizu’s CLR Phonetics Laband Professor Masaichi Takeuchi of Nagoya Universityof Arts. We believe that these results will be very usefulfor musicians who are teaching and learning to play clar-inet and trumpet. We are aware of only one other studythat has been done looking directly at the tongue duringthe playing of a wind instrument [5], but in that studyonly clarinet tonguing was analyzed.

flat” [tongue position: normal (237 Hz), too low (233Hz), too high (239 Hz)], “D” [normal (301 Hz), too low(295 Hz), too high (300 Hz)], “Lip Slur” [home-base po-sition (299 Hz), too low (237 Hz)], and “Tonguing” [nor-mal (357 Hz), too high (359 Hz)]. The clarinet playerplayed “Slur” [good (265 Hz), bad (267 Hz)], “Tongu-ing” [good (314 Hz), bad (316 Hz)], “Staccato” [good(314 Hz), bad (297 Hz)]. All of these pitches belong toRegister 1.Second, spoken data was collected from both players.

They said “tatata”, “tititi”, “tututu”, “tetete”, “tototo”,“kakaka”, “kikiki”, “kukuku”, “kekeke”, “kokoko”,“takataka”, “tikitiki”, “tukutuku”, “teketeke”, “toko-toko”. We collected and recorded these data with ultra-sound and iMovie HD (Figure 1).

2.3.2 Data AnalysisFirst, we selected the Japanese vowel sounds ($"[a], $$[i], $&[W], $([e], $*[o]) from the spoken data, as wellas images of the tongue while playing. We used iMovieHD to scroll through the movies and choose the clearestimages.Second, we used EdgeTrak [9] to put 33 red dots on

the white surface-of-the-tongue line in the ultrasoundimage, and saved each coordinate as a “.ts” file (.ts filescan be read with a text editor). Then, we used a MAT-LAB program (based on one developed by Maekawa[10]). This program read image files (.JPEG) and the.ts files to measure the distance between the ultrasoundprobe and the intersection of the tongue surface line (seeFigure 2). Next, we compared each of the four distancesbetween playing images and speaking images. Finallywe discovered the distances where the di!erences aresmallest.

3 ResultsWe compared the good “Tonguing” position with each ofthe five vowel sounds in various consonant contexts, andin Figures 3 to 6, we have colored black the bars wherethe di!erence is at a minimum. In Table 6, we summa-rize the results of Figures 3 to 6, and we give the actualdistance di!erence between the playing tongue positionand the given vowel sound.

Distance Trumpet Clarinet1 [o] in “ko”: -14 mm [e] in “te”: +2 mm2 [a] in “taka”: +3 mm [o] in “ko”: +3 mm3 [o] in “ko”: +1 mm [e] in “ke”: -2 mm4 [o] in “toko”: -2 mm [e] in “ke”: 0 mm

4 DiscussionThe four distances that were measured in this research(as seen in Figures 3 - 6), are the distances from the ultra-sound probe to four points on the surface of the tongue.Specifically, these points are from the tongue body to thelower tongue root. For both the clarinet and the trumpet,

three out of the four distances indicate the same vowel;only Distance2 is a di!erent for each instrument. Thereason that Distance2 seems to be special is because aclarinet player’s tongue tip is pushed down by the reed.Thus, the tongue body position (Distance2) while play-ing the clarinet is lower than the usual speaking tongueposition. That is why for only Distance2, the closestvowel sound is [o] for the clarinet. For trumpet play-ing, Distance2 was closest to the [a] in “taka” but the [o]in “ko” was a very close second place.When comparing our results to the advice given by the

various professionals, for clarinet our results are closestto West [4], although not exactly the same. For trum-pet though, our results di!er from all published advicegiven in Table 2. One reason for our results not match-ing published advice is that the advice in Tables 1 and 2is for speakers of languages like English or German, notJapanese. English vowels di!er from Japanese vowels,

so the language musicians speak will a!ect their play-ing tongue position if they are modelling their playingtongue position after a vowel in their native language.In this research, we collected data from only one clar-

inet player and one trumpet player, so it is di"cult for usto make generalizations based on that data alone.

5 Conclusions and Future WorkIn conclusion, our results showed that the Japanesevowel [o] is the closest tongue position while playingtrumpet register 1, and the Japanese vowel [e] is theclosest tongue position while playing clarinet register 1.These results were closest to West [4] for the clarinet,but they were di!erent from any previous advice for thetrumpet.In future work, we would like to research the case of

players whose native languages are not Japanese, andbased on this research, we would like to help make ped-agogical materials and tools for music classes.
