揉弦是小提琴演奏最常用的技巧之一,揉弦可以讓琴的聲音變得婉轉悠揚,可以說揉弦是小提琴的靈魂所在。很多人在學習的基礎階段還挺順利,但是到了練習揉弦的時候,就遇到了瓶頸,一直處於止步不前的狀態。本期逆月音樂為大家介紹揉弦小提琴的練習方法,希望可以對正在學習揉弦的朋友有所幫助。
 
 

 
 
揉弦的三種方法:通常我們接觸到的揉弦有三種方法:手臂揉弦、手腕揉弦、手指揉弦。這三種不同的揉弦其效果自然不同。
 
手臂揉弦主要依靠小臂顫動,聽來熱情飽滿。手腕揉弦主要依靠手腕顫動,聽來舒展委婉。而手指揉弦則依靠手指關節顫動,聽來則柔美細軟。掌握這三種不同的揉弦方法,並能運用自如,自然會使演奏的音色變化,進入非同一般的美妙境界。遺憾的是,許多演奏者從一開始就習慣了某一種揉弦方法。因此,其演奏的音色也就顯得貧乏和單調。
     
 
初學也是最重要的揉弦還是這兩種兩種:一種是手臂的揉弦(圖1),一種是手腕的揉弦(圖2)中,手腕的的揉弦只動手腕以上,手臂的揉弦是動整個手臂兩者的差別是:手腕的揉弦,音高變化比較小,表情比較細緻,適合比較甜美的樂段。手臂的揉弦,音高變化較大,適合比較粗獷的樂段。兩種揉弦都要會,對揉弦才有完整的了解。
 
 

 
 
 
這兩種揉弦相同的地方是手指都會動,只是發力的點不同,一個是從手臂發力,一個是從手腕發力
 
 

 
 
 
知道了基本揉弦之後,練習過程中我們有什麼需要提前注意的點呢?
 
  特別注意:這里特別要指出的是,許多琴童初學揉弦時沒有正確的方法。因此通常出現兩種弊端:一種是震顫動作過快,不能自控,形成痙攣式的顫抖聲音就如同小山羊咩叫。另一種則是動作過於緩慢,手腕處不規律的扭動,其聲音就如同沒有上足發條的留聲機音響。學習揉弦的正確方法:首先應學會手腕揉弦。其方法可先將手臂放在大腿上或椅臂上,然後將手腕放鬆前後搖動,力求平均,待動作習慣自如後,再放到指板上練習。
       注意:大指和虎口之間不要捏緊,手指在指板各音的位置上前後揉動時重要的是強調手腕後仰的動作,然後再往前回到原位。而萬萬不可一味往前揉動,而沒有後仰的動作。
       同時要注意:在手腕前後揉動時,帶動手指的關節,手指的觸弦點不能隨著手腕的揉動而移位。在練習手腕揉弦時,可先從三指開始。因為用三指揉動可以使動作更為寬鬆,然後再練習二指和一指。而練習四指時,還可將三指緊靠四指幫助揉動。這樣的練習會使顫動的效果更為自如。在手腕揉弦練習的基礎上也可逐漸學習和熟悉手臂的揉弦和手指的揉弦。目的是為了更好的豐富演奏上的表現力,適應於各種力度和情緒變化的需要。當然也有一些演奏家,一開始就習慣手臂的揉弦。他可以將手臂顫動的幅度和快慢控制得非常自如,同樣富有極好的表現力,也實屬難能可貴。小提琴演奏中的揉弦,如同歌唱演員演唱時的顫音一樣,人們可以從中感受到他的氣息和情緒的變化。好的揉弦和好的運弓巧妙地結合在一起,其演奏必將和美妙的歌唱一樣,沁人心肺,動聽無比。
 
 

 
 
 
因此揉弦通常最大的問題在於:如何使手指能夠按住弦,但是手指的關節同時又能保持放鬆,使手臂或手腕活動的時候,能夠帶動手指活動造成揉弦的效果。 (在這邊要先提醒一下,揉弦時手指的活動是被手臂或者手腕帶動的,手指本身並不需要出力量,不可用手指出力造成手指活動。)
 

 
因此問題是出在按弦的方法上,按弦的時候,如果是以手指出力壓緊弦,手指便會僵硬無法活動。 (如圖)正確的按法是要手手要放鬆,利用地心引力的重量帶動手指向下壓,手指本身像是衣架一樣掛在指板上,感覺手指本身俱有重力站在指板上。 (如圖)
 
 
那麼在日常的練習中我們應該如何分步驟的來練習呢?
 
揉弦是小提琴重要的技術,可以讓琴發出的聲音變得動聽,充滿感情。那揉弦是如何練習,並且需要注意哪些點呢?今天我來講一講。
 
第一步,學生要把琴夾好,固定住小提琴。這十分重要,當揉弦練習進行時,手會在緊張的狀態下不斷晃動,用手持琴是不合理的。這裡講個方法,找一面牆,在琴頭上墊一塊軟布,將琴頭垂直頂在牆上,這是最穩固的。力量要控制好,一是,頂牆的力量要合理,不要損傷琴。不能前傾身體,讓人的部分重量施加於琴。只通過站位與牆體形成輕微的作用力。二是,左手需少許托起,不能完全鬆弛,掛在琴脖子上。否則會把琴頭向下拽,使琴頭與牆產生刮擦,即使有軟布隔著,也怕擦傷。
 
 
第二步,保持左手握琴的手型,稍稍鬆開,使整個左手都不碰琴,做模擬揉弦的動作。用手臂揉弦的,進行手臂的動作,用手腕揉弦的,進行手腕的動作,琴頸保持在虎口和手握的空間範圍內,但不碰手。讓手在沒有任何來自琴的阻力的情況下,學習跟隨臂腕運動。要保持好運動的節奏,均勻平穩。
 
第三步,將一個演奏用的手指按在弦上,大拇指依然在空中,其他手指抬起,模擬揉弦。這裡要說的是,如果大拇指不碰琴,只有將小提琴固定好,按弦的手指才能夠將弦按住。所以要先把第一步調好。按上一個手指之後,繼續按第二步的樣子,做手臂或手腕的動作。按在弦上的手指,不可以有滑動。這對按弦手指的柔韌性調整要求很高,既不能太軟,也不能太硬。此項要注意保持好手指運動的幅度。
 
第四步,將每個演奏用的手指分別按弦進行訓練後,可以把大拇指輕輕靠在琴頸上練揉弦。這個變化,使原先整個手部的運動,變成只有大半隻手掌的運動。因為大拇指,將左手手掌的左邊緣鎖住了,使左側掌不再隨著手臂或手腕的運動而大幅移動。這時會感覺揉弦的幅度受限,必須加大揉弦力量,適度放鬆手掌的肌肉,使揉弦手指前後運動的幅度,恢復到大拇指懸空時的狀態。
 
第五步,在揉弦時拉弓,這很不容易。到了這一步,琴依然是頂在牆上的。拉弓要慢,要輕,得靠大腦認真協調。尤其註意,左手快而有規律,右手慢而平穩,右手拉弓不受左手影響,運弓連貫。要仔細聽,有沒有揉弦的效果,如果只有動作,而沒有聲音效果,或聲音效果很弱,可能是按弦的手指尖太僵,手臂或手腕運動力量不足,或是大拇指太緊,手掌過硬,需要調整。
 
第六步,把琴從牆上移開,手持琴揉弦,拉弓,檢驗成果。
 
基礎揉弦的每一步都需要花費時間來熟悉和調整,並不能很快地進行。要盡量讓穩定、運動、幅度、節奏都做到最好,起初可能是不順利的,如果沒有耐心,便會心浮氣躁。一般兒童學習揉弦,需進行半個月到一個月時間的針對訓練,才能在小提琴演奏的過程中使用揉弦。

Vibrato is one of the most common violin playing techniques. It is the soul of the violin and gives the instrument a beautiful sound. Many people learn the basics of the violin quite well, but when it comes to practising vibrato, they encounter a bottleneck and remain at a standstill. In this issue, we would like to introduce you to the methods of practising vibrato on the violin, which we hope will help those who are learning to vibrate.
 
 

 
 
There are three types of vibrato: arm vibrato, wrist vibrato and finger vibrato. These three different types of vibrato naturally have different effects.
 
Arm vibrato relies mainly on the tremolo of the small arm and sounds passionate and full. Wrist vibrato relies mainly on wrist tremolo, which sounds spacious and gentle. Finger vibrato, on the other hand, relies on finger joint tremolo and sounds soft and delicate. Mastering these three different types of vibrato, and using them with ease, will naturally bring the tone of the instrument into an extraordinary state of beauty. Unfortunately, many players become accustomed to a particular vibrato method from the outset. As a result, the tone of their playing becomes poor and monotonous.
     
 
The difference between arm vibrato and arm vibrato is that with wrist vibrato there is less variation in pitch and the expression is more delicate, making it suitable for sweeter passages. The arm vibrato is more varied in pitch, and is suitable for the more rugged sections. It is important to know both types of vibrato in order to have a complete understanding of vibrato.
 
 
 

 
 
Both types of vibrato are similar in that both fingers move, but the point of attack is different, one from the arm and the other from the wrist.
 
 

 
 
 
Once we know the basic vibrato, what do we need to pay attention to in advance during practice?
 
  A special note: It is important to note that many children do not learn vibrato properly when they first start. One is that the tremolo is too fast and uncontrollable, resulting in a spasmodic trembling sound like the bleating of a goat. The other is that the movement is too slow and the wrist twists erratically, resulting in a sound like a gramophone without a full bar. The correct way to learn how to vibrate a string is to first learn how to vibrate the wrist. This can be done by placing the arm on the thigh or arm of a chair, then relaxing the wrist and shaking it back and forth, trying to be even, and then putting it on the fingerboard once you are comfortable with the movement.
       Note: Do not pinch between the thumbs and the tiger's mouth. It is important to emphasise the backward movement of the wrist when rubbing the fingers forward and backward on the fingerboard. It is important not to simply knead forward without leaning back.
       It is also important to note that when rubbing the wrist forward and backward, the joints of the fingers are driven and the touch points of the fingers are not displaced by the rubbing of the wrist. When practising wrist vibrato, you can start with the third finger. This is because kneading with three fingers makes the action more relaxed, and then you can work on two and one fingers. When practising the fourth finger, the third finger can also be placed close to the fourth finger to help with the vibrato. This will make the trill more comfortable. The wrist vibrato is the basis for learning and becoming familiar with arm vibrato and finger vibrato. The aim is to enrich the expressive power of the instrument and to adapt it to the needs of the various forces and moods. There are, of course, some players who are used to arm vibrato from the very beginning. They can control the amplitude and speed of their arm vibrato with great ease, and with great expressiveness, which is also very valuable. The vibrato in violin playing is like the vibrato of a singer who sings, and one can feel the changes in his breath and emotion. The combination of a good vibrato and a good bowing is as heart-warming and beautiful as the singing.
 
 
 

 
 
The biggest problem with vibrato is how to keep the fingers on the strings, but at the same time keep the joints of the fingers relaxed, so that the movement of the arms or wrists can lead to a vibrato effect. (It is important to remember that the fingers are driven by the arm or wrist during vibrato, not by the fingers themselves, and that they should not be used to cause finger movement.)
 

 
If you press the strings with your fingers, they will become stiff and immobile. (The correct way to press the strings is to relax the hand and use the weight of gravity to push the fingers downwards, with the fingers themselves hanging on the fretboard like a coat hanger, feeling that the fingers themselves are standing on the fretboard with gravity. (see picture)
 
 
So how do we practice this step by step in our daily practice?
 
Vibrato is an important technique for the violin, making the instrument sound beautiful and full of emotion. How do you practise vibrato and what do you need to be aware of? Today I will explain.
 
The first step is to clip the violin in place and hold it in place. This is very important because when vibrato practice is in progress, the hands are constantly shaking under tension and it is not reasonable to hold the violin in your hand. The most secure way to hold the violin in place is to find a wall and place a piece of soft cloth on the headstock and hold the headstock vertically against the wall. This is the most stable way to hold the instrument. The force should be controlled, firstly, the force of the wall should be reasonable so as not to damage the instrument. It is important not to lean forward so that some of your weight is applied to the instrument. Only a slight force should be exerted against the wall through the stance. Secondly, the left hand should be held up a little, but not completely loose, hanging on the neck. Otherwise, the headstock will be pulled downwards, causing it to scrape against the wall, even with a soft cloth between them.

The second step is to keep the left hand in the shape of the instrument, loosening it slightly so that the whole left hand is not touching the instrument, and doing a mock vibrato. For arm vibrato, do the arm action, for wrist vibrato, do the wrist action, keeping the neck within the space between the tiger's mouth and the hand grip, but without touching the hand. Let your hands learn to follow the arm-wrist movement without any resistance from the instrument. Keep the rhythm of the movement even and steady.
 
In the third step, press one playing finger onto the string, with the thumb still in the air, and lift the other fingers to simulate vibrato. It is important to note here that if the thumb is not touching the instrument, the finger pressing the string can only hold the string if the violin is held in place. So it's important to get the first step right. After pressing the last finger, continue with the arm or wrist action as in step 2. There should be no slippage of the finger on the string. This requires a high degree of flexibility in the fingers, not too soft and not too hard. Care must be taken to maintain a good range of finger movement.
 
The fourth step is to train each playing finger on the strings separately and then to practice vibrato with the thumb resting gently on the neck. This changes the movement of the whole hand to just the palm of the hand. This is because the thumb locks the left edge of the left palm so that the left palm does not move so much with the movement of the arm or wrist. It is necessary to increase the vibrato force and relax the muscles of the palm so that the range of motion of the vibrating fingers is restored to that of the thumb when it is suspended.
 
The fifth step is to draw the bow during the vibrato, which is not easy. At this point, the instrument is still on the wall. The bow has to be drawn slowly and gently, and the brain has to be carefully coordinated. In particular, the left hand should be fast and regular, the right hand slow and steady, and the right hand should not be influenced by the left hand, so that the bowing is consistent. Listen carefully for vibrato. If there is only movement but no sound effect, or if the sound effect is weak, the fingertips pressing the strings are probably too stiff, the arm or wrist movement is not strong enough, or the thumb is too tight and the palm is too hard, and needs to be adjusted.
 
Step 6: Remove the instrument from the wall, vibrate the strings with the instrument in your hand, draw the bow and test the results.
 
Each step of the basic vibrato takes time to become familiar with and adjust, and cannot be done quickly. Stability, movement, amplitude and rhythm should be as good as possible, which can be unpleasant at first and can lead to impatience. The average child learning to vibrate needs between half a month and a month of specific training before they can use vibrato in their violin playing.
