1、葫芦丝、巴乌的演奏指南（Guide for playing Hulusi, Bau）A, hulus, structure, range and classification of Bau1, structure: first introduced gourd silk, gourd resonance role. The flow of air passes through the hoist to the head and pipe.The charge is mainly developed on the head tube, with seven per hole, a sound h
2、ole two rope hole.The tube is divided into a treble attached tube and a bass attached tube, all of which continue to produce a sound. The ordinary gourd has only one attached tube to sound and the other is only for decoration. The tube stopper needs to be opened when the tube is attached and closed
3、without need. The tie and the organic coordination of the head make the music colorful and vigorous.The tying of the cord is mainly to tie the head and the tube together to strengthen the stability of the musical instrument structure.In charge of the tail plug, the role is to make the bass sound rou
4、nded, pay attention not to push.The structure is simpler than the Bawu and cucurbit shape and bamboo flute is similar to that of the principle, method and playing Hulusi is basically the same.Range: 2, hulus, Bawu pronunciation tube is provided with seven according to the sound to sound tube 5 as an
5、 example, its range is 3 to 6 bass baritone, (model), the range was narrow but highly expressive.3, classification, hulus are F, D, C small small, bB, A, G, adjusted F, bE, adjusted D, adjusted G used Bawu and F keys.Two, press the hole position and hand shape1, press hole positionTo blow out a norm
6、al voice, it is a must do, who demanded the closure of holes is not a leak, can not leak, otherwise, the sound is not accurate, let a person feel not too harsh. In order to guarantee according to the sound hole does not leak, we use the finger belly to avoid finger holes, and the holes according to
7、the waist. Because the belly area refers to the finger tip and finger waist to be wider, and secondly refers to the belly, according to the hole, hand shape is more beautiful, and easy to play, so we use the hole according to the belly according to the hole.2, hand shapeIn order to ensure that the h
8、and is beautiful and easy to play, the requirements of the opponents shape are particularly important, and these postures should be avoided. The inverted wrist (so-called inverted wrist or the palm of your hand and wrist angle formed by collapse, so the wrist which makes finger hole movements become
9、 clumsy, second look from the exterior to make people feel very uncomfortable, the right wrist angle should be close to 180 degrees, so that the finger flap is beautiful and flexible; (II) wing the wing is pressing his hands hole posture is like aircraft wings, fingers and head into a form not beaut
10、iful angle, often return with finger joint too flat, curved fingers are not normal, so playing and finger movements will seem stiff); the peacock type. (peacock type is mainly formed in the open hole after the other fingers, finger holes left, away from the hole, this instrument back to cause instab
11、ility, no sense of reality. Secondly, because the sound so high from the fingers, when closing the hole when the fingers can not accurately into the corresponding holes on). I hope you avoid all three or other abnormal postures.First of all, pay attention to the two index finger, do not attach to th
12、e attached tube, this will affect the beauty and future performance, the whole hand shape should be Tong, loose and empty.Secondly, the application of the little finger of the hand is an important factor in determining the shape of the hand, and the two little fingers play three roles:Is to play the
13、 fixing function, for beginners to rely mostly on the index finger fixed Hulusi, they formed a peacock type above mentioned. Organically, the little finger is used for fixing, and the two index fingers can be liberated, and the hand shape is beautiful.It is the positioning, some students played the
14、three hole, which will start up after the shift, to be playing to the three hole when the corresponding holes can not find the location of the little finger when using fixed will avoid dislocation of fingers and holes.It is the guarantee of hand shape appearance, avoid using the little finger of the
15、 peacock, the little finger will limit the height of the other fingers, it is to avoid the peacock, achieve beautiful in shape.The application of the little finger of the beginners can not be ignored, its applying rules: when used to start the three finger little finger should be lifted, otherwise i
16、t will make three to play less flexible, when not under three finger little finger should be placed in charge of the appropriate position, fingers, too, to be skilled, habit the little finger, the application would not have too much attention, especially in the fast playing music, the little finger
17、is used more and more free, not to be affected by this restriction, otherwise it will affect the speed and care for this and lose that finger, smooth melody.Three, to avoid goo soundHulusi, Bawu pronunciation is very special, such as weak breath sound issued from A to Z only a goo sound, beginners u
18、sually back there is such a phenomenon, we can try to slowly force the sound is changed to normal, that is to say, hulus Bawu playing breath need certain strength, especially the bass playing strength stronger, the sound is normal.Most beginners when you can blow a normal tone will encounter two pro
19、blems, one is the sound head always goo sound sent out first then make the normal sound, the two is when after blowing a sound, the sound will always bring out a tail goo sound. First solve the sound head goo sound, most beginners are called to play the sound head, we can feel, call out of breath, g
20、as head is soft and weak, the sound is goo sound, and with the increase of flow intensity, only normal pronunciation. In fact, the solution is very simple, as long as you use spit sound at the beginning of Gu sound can be avoided. Why can spit sound be avoided?. Because we spit sound in an explosive
21、 action, we can understand what we know, certainly with certain strength and explosive strength, make the air out of reach normal sound need strength, can make the instrument produces a normal voice. So, as long as we start with spit sound, the sound head will be clean and fresh.The second is to sol
22、ve the end goo sound, when after blowing a sound, especially the 567 tone three is more serious, it will appear goo sound, sounds very uncomfortable, why is this goo sound, because when you blow a tone, in fact, oral there are more than gas, the residual gas is released, almost no strength and stren
23、gth, so this part of the sound of gas is the goo sound, we want to avoid it, only after blowing, quickly put the lips open, air break, residual gas is still retained in the mouth, can avoid aftersound goo sound.Four, the use of breathThe use of breath, are particularly important in all music, especi
24、ally the control of breath in the Hulusi, the intensity of the Bau, distribution, is an important part in playing Hulusi, Bawu, mainly about the musical scale when the use of breath. There is obvious difference between Hulusi, Bawu luck and other musical instruments, musical instruments in general w
25、hen playing to the treble part requires a certain strength and strength, relative to the bass to play harder, and Hulusi, Bawu on the contrary, the more high airflow will be weak, especially high 5 and 6 play just then, a slow flow. On the other hand, it may cause treble damage, air flow or no music
26、 at all. Therefore, the beginner must pay attention to the airflow when playing high notes.Why Hulusi, Bawu use of breath so special, from reed structure speaking you might be easier to understand the heart of spring element Hulusi, Bau, it is like a bird by the middle of this piece on the tongue un
27、der vibration and the resonance and sound of bamboo. It is characterized by narrow head to the root is gradually widened, the head is sharp, the root is wide, we can understand this: the root of the vibration is the bass sound, because the root is wide in vibration when the air needs to be strengthe
28、ned; vibration tip is determined treble sounds, because the head is sharp edge in vibration without air is too strong, for each sound hulus, then the Bau efforts are not the same, that is to say we must find the best efforts to play a little of this sound, not strong nor weak, we usually say in plac
29、e this reflects well, so why beginners blow out music, the main reason is that the best flavor strength of point is not found, there is usually high pitched voice, bass drum sound distortion, high or high, Hair, sand and so on these phenomena, the reasons for excluding musical instruments, the main
30、reason is the problem of breath dynamics.Five, bass 3 practicePerhaps there is a song we are very familiar with, that is a beautiful place, the song with cucurbit flute Dai Flavor effect is excellent, full, but the most worrying is that 3 of the songs in the bass playing, some students dont know how
31、 to play the instrument itself or the sound is not allowed, so we can only avoid playing or over 8 high degree of performance, but now this is the first beautiful song will have regrets. If the bass 3 can be played and played well, our playing range is much wider, such as a beautiful place, so that
32、the bass 3 can be played completely.Bass is 3 Hulusi, Bawu unique sound, the fingering and bass 5, which closed holes generated by the airflow so slow sound is the bass bass 3, 3 other than sound full, practice must flow slowly, feeling is not hard, just gently put the gas out, bass 3 as the voice c
33、an not spit outs, playing with the call. 3 separate bass exercise is very easy, but if you practice 3 bass control and other audio conversion has certain difficulty, such as conversion and bass 5, same fingering completely rely on the strength of the airflow to play, the control of the atmosphere of
34、 the demand is very high.Practice and application of six, glideIn the Hulusi, Bawu playing the role of portamento is to make the sound and tone transition, do fruity, elegant and smooth and rich ethnic style, especially the use of Dai style music playing the indispensable glide.These can be divided
35、into the upper and lower portamento portamento. Inverse parabola identified by the glide, by its way of playing bass to treble, finger from the bass to treble with dynamic lift on the glide performance just remember a word, a finger directly lifted into wiping action lift on the glide effect of natu
36、rally occurring.Under the glide and slide up from the symbol instead, see it with positive parabola to identify, from playing up to see if it is by its way of playing bass to treble, is gradually closed by the finger hole to treble bass hole is closed by direct becomes gradually closed under natural
37、 glide.Hulusi, Bawu playing in the upper and lower glide ornament, make music performance more attractive and characteristic. From the micro perspective in slow playing, almost every note by glide this technique, difference is accounted for by the length of time, in the process of teaching often emp
38、hasize the feeling of finger holes, especially important, this is an important factor in determining whether or not the beautiful music.It is difficult to glide in is beyond four degree range glide, this close matching of fingers, coordination requirements higher, should be in place to practice.Prac
39、tice and application of seven, a sound, itsPlay is widely applied in the sound in the Hulusi, Bawu playing, playing sound similar to the notation commonly used in audio handle, the melody is parallel, it can replace the tongue to separate the same degree of sound, the playing method is played a very
40、 short time when the low two degrees at the same pitch. Beat the sound faster, fingers should be strong and flexible. It is similar to the notation and the word, playing and playing music in it.Eight. Practice and application of vibratoThe common techniques of vibrato in flute, Bawu in music, a tril
41、l, the expressive force of the music is more abundant. In particular, the rapid vibrato in the climax can be exciting. Such as Golden Peacock, the two song Affectionate Bawu popular music, in addition to its beautiful melody, the important point is the use of the tremolo playing music is more cheerf
42、ul, full of charm, it is intoxicated.A can make the blown out of the sound wave feeling in music with the TR logo, playing method is very simple, so in between and above the two degree sound repeatedly, and if you need a few degrees above the sound repeatedly, usually tr plus a digital Arabia as in
43、tr above the mark so that 3 said the above three degrees and repeated tone. If the TR did not identify any number above, and said the above two degrees in the audio play repeatedly, Hulusi, vibrato is generally 3 Bawu playing 3535353, instead of playing 3434343, because this play from the hearing on
44、 the first uncomfortable, because 4 of the sound in Hulusi, Bauri, it is not indeed, the second 4 fingering is a bit complicated, 3 and 4 fast conversion, seem very strange very difficult. Therefore, 3 of vibrato, without special requirements, usually play 35353.Vibrato exercise is a long-term pract
45、ice, the method is simple, but skilled and fast, it takes a certain amount of time, practice from slow training start, to be skilled, gradually accelerated. When you practice, fast or slow, keep pace. Dont go too fast or slow. Pay attention to training your hands and fingers.Nine, refers to the prac
46、tice and use of the tremolo and vibratoThe tremolo is also called virtual finger vibrato, also called every hole play sound, generally use the symbol O logo, is refers to the tremolo Hulusi, Bawu important skills in Dai style music with most. The method is very simple, as the name suggests, every ho
47、le in the sound position under the two hole, smooth finger flap, produce a similar string effect. To press 5 for example, when playing with 3 ring finger flap 1 holes, 2 holes play beat 7 other by analogy.The tremolo practice although the movement is simple, but to practice it takes a Kung Fu, is ma
48、inly a finger to do exercises, beautiful appearance, uniform speed, speed can control freely, the sound should be rounded, not a trace, how to do the best effect on virtual means vibrato? Most players love the virtual means every time the vibrato sound very close. Indeed, the effect is not the best,
49、 this will make the sound fibrillation significantly, no sense of beauty but that is a noise, you can try fingers fluttering dont carry the sound off. Just close the sound 1/3 position, there will be what kind of effect.Gas tremolo, also known as belly tremolo, general symbol logo, it is the law by breath strong alternately formed a sonic wave,
