If the student makes use of a sliding-pin these instructions cannot be observed in every respect, the legs are not required to hold the 'cello, the left knee alone being brought into use as a slight support--not to hold the instrument from the ground, but to prevent it from rocking backwards and forwards.
In this matter I would like the student to understand that attitude does not assist in the production of music, but do not let the reader imagine that if unnecessary posing does not help, awkward and uncouth positions of the players do not take away from the effect. Anything which distracts the attention of the audience from the music should be rigidly avoided; awkward attitudes, and grotesque motions of the head and body should therefore be instantly suppressed by the teacher or the private friends of the student.
Piatti, who does not use a 'cello peg, holds his instrument in a correct manner, not shuffling about or varying his position. Now if the reader ever has a chance of hearing Van Biene, let him observe the manner in which that artist holds his 'cello. We have here the two extremes; as Piatti is of the strictly correct order, Van Biene is of the exaggerated artistic order, all the time he is playing constantly striking some fresh attitude. If Van Biene had again to take to concert work, I have no doubt that he would calm down a little in this respect, his exaggerated style while being very effective on the stage, would not be tolerated on the concert platform. By all means let the student use a sliding-pin, but let him take advantage of the greater facilities which are offered, to make his attitude more artistic, always adopting the happy medium in _this_ matter at least, correctness--without awkwardness, artistic grace--without unnecessary vain posing. As a first class elocutionist seeks by attitude to help the effect of his words, not to distract the attention of his audience, so the attitude of the 'cellist must be pleasing and easeful. If the student will compare (Fig. 1) with the plates usually published with 'cello schools, especially the two previously mentioned, he will see the importance of the matter.
There can be no departure from the acknowledged way of holding the bow if the best results are to be obtained, that is to say, that the rules must be strictly observed as far as the individual shape of the hand will allow. It will be observed that the nut of the 'cello bow is scooped out on the inner side, which forms two projections, one of these, the lower one, is surrounded with metal through which the hair of the bow passes, the upper projection fits against the stick. The extreme tip of the thumb should be placed on this upper projection (Fig. 2) so that it is also partly on the stick, the thumb being assisted in holding the bow by the second and third fingers. The second or middle finger is so placed that the tip touches or overlaps the hair close to the lower projection; the third finger falls naturally into its place next to the second finger, and has its tip touching the metal, or silver ferrule on the lower projection (Fig. 3). These two fingers and thumb are all that are required to hold the bow, the fourth finger serves to balance the bow and should be placed lightly on the stick, its chief work being to prevent the bow dropping too much when playing at the heel, and to ease the pressure on the strings in very light passages. Last but not least comes the first finger; this is the member which is responsible for quality and quantity of tone, it should have a slight bend round the stick, and so that the other fingers do not interfere, it should be placed slightly apart, this also helps to bring out a louder tone if required. The first finger like the fourth is not compelled to remain stationary, thus in long semiquaver _sautillé_ passages, where the extended position of the first finger would interfere with the natural spring of the bow, it should be made to relax its pressure and take a position nearer the second finger; again in long sustained heavy notes the first finger may be extended slightly, so that more pressure may be put on the bow. These last remarks are most important, as the whole success of the student's bowing rests on the correct use of the first finger, and the proper position of the thumb. I cannot quit this subject without mentioning the importance of having the muscles, especially the tendons on the back of the hand, perfectly easy when the bow is in position.
