RE: Rasgueo-Rest (in reply to Richard Jernigan)

quote:
Much of this change requires rotation of the forearm at the elbow joint. Resting the forearm on the edge of the guitar inhibits this rotation. Actually I have since years come to personal impression that about any technique will executed best with a howsoever subtle rotation of the forearm, as it reduces the required amount of individual fingers engagement. Seeing Iznaloa play in a video for first time weeks ago, I noticed his arpeggio executed with a distinct rotation too ( with his ellbow rested ). Your observation that resting would inhibit rotation is not true. I do it all the time. The rotation ends up in very small movement near the ellbow, which will be easily taken by the tissues flexibility ( still with muscular arms ). quote:
Now the wrist bends downward, instead of rightward. Still, for many players the stroke is not perfectly perpendicular, and virtuosos like Scott Tennant advise "ramping" the shape of the fingernails. Then we hear he has stopped doing it himself. Wrist bending downwards( palm towards forearms flexors ) has good ergonomic reason. It supports execution within the fingers poise range / reducing active repositioning / hampering through active extensors. ( Paco Pena touts it since decades.) Sideways however will empasize fingers deviation in length and enhance demand in compensation / active repositioning. Questioning whether highly renowned artists could be stupid for lesser ergonomical technique won´t really help with exploring general physiological conditions. Just as admirable performance mustn´t inevitably be equalling most efficient / ergonomical execution in the same time. Further, lesser ergonomical posture / preparation at times can be helpful in individual situations like for temporary alteration / release / recovery after over strained playing situation. Yet, it won´t present a generally ergonomic approach, rather than a momentary relief. Should we instruct a beginner to stick his RH pinky out, only because Paco de Lucia does it / can, despite, overcome such a hindrance? Certainly not. Besides, the way of resting the arm that you describe, because of the bouts slope will remain no true rest. It takes brest muscles, the latissimus and the shoulders to both press the arm laterally and lift it. Even if you might not notice the efforts due to habit. Also, a forearm suspended by engagement of the upper arms muscles introduces not only constant demand to actively keep the hand in position, but also hampers the lower arms and hands muscular apparatus. If you´re curious about how apparently remote body parts effect external limbs down to the finger tips, for an example try to focus on relaxing your neck before raising your arms to play and watch how magically right- and left hand cooperation can improve ( as long as you´ll keep the neck relaxed ). Differences with flamenco and classical guitar unquestioned, principles like reducing movement / efforts to a required minimum remain useful for both, like with any art. Accordingly, imperfect flamenco technique might show a lot of up and down movement of hand / forearm, while advanced technique will as much as possible reduce rotation to a rolling forearm, with the wrist actually showing relatively little of vertical movement. ( Advanced technique will also reduce individual fingers activity to a minimum, be it during whirls, rasgueados, arpeggios, picados, thumb techniques and what have you. Usually by said economy through upper limbs.) Who knows, maybe one day I´ll discover to have been wrong, though quite doubting yet. Until now however that popular "to each his own"- mantra, technique wise to me appears to be moonshine, as long as we´re talking average people whose physiology tends to be quite the same. Limbs proportions to each other, muscle / tendon connections etc. being outlayed in quite the same way, and thus their optimal coordination too. Naturally, certain things will be harder or easier to execute for the individual player. However rather due do to motoric habits ( and their following detours) than to any immovable factor. And as it commonly being all the same approaches / postures / preparations that abet further techniques, it shouldn´t hurt to recognize those and spare oneself superfluous efforts / paths of potential stagnation. As an original autodidact dummy, I think to know in relative detail why notice and acceptance of general physical points could be of practical sense. Correct and detailed envision ( if that´s a right expression ) is the key. - So, Richard, would you try such an armrest first, or keep dismissing it in advance like a mulish dromedary?

ORIGINAL: Ruphus Besides, the way of resting the arm that you describe, because of the bouts slope will remain no true rest. It takes brest muscles, the latissimus and the shoulders to both press the arm laterally and lift it. Even if you might not notice the efforts due to habit. Not at all. If the guitar were held as you describe, it would indeed cause problems. It has for many players. In the traditional position done right, however, the guitar is held with the neck pointing somewhat upward, so the inward slanting part of the side is horizontal. Then the guitar is held purely by the weight of the arm, not by muscular tension. In the "Paco position" the arm indeed contacts the guitar on the curve of the lower bout. The waist is placed over the right leg, which is stabilized either by crossing the right ankle over the left knee, or by the leg resting against the chair. The angle of the arm and the pivot of the shoulder cause the weight of the arm to exert a slight force to the player's left on the guitar. This is balanced out by the reaction of the right leg against the waist of the guitar. Again, the weight of the arm is sufficient to hold the guitar without any muscular tension. Is it reasonable to think that generations of virtuosi, each spending tens of thousands of hours, would not have arrived at an ergonomically efficient way of holding the guitar? There are at least three ways: the classical position, illustrated in numerous photos of Tarrega in the 19th century; the traditional flamenco position, illustrated in photos of Ramon Montoya and many others in the first part of the 20th century; and the "modern" flamenco position. I put "modern" in quotes because Sargent's "El Jaleo", contemporary with Tarrega in the 19th century, gives a very accurate portrayal of how Paco holds the guitar. quote:
Also, a forearm suspended by engagement of the upper arms muscles introduces not only constant demand to actively keep the hand in position, but also hampers the lower arms and hands muscular apparatus. The upper side of the guitar is closer to the body than the lower, tilting the top slightly toward the ceiling. Thus a part of the weight of the forearm is directed toward the guitar top. This part of the weight lends more power to the action of the right hand. Adopting the traditional flamenco position with my best classical guitar alters the sound radically by changing the action of the right hand from its classical version to flamenco. In picado, arpeggio, pulgar and alzapua it becomes a very good flamenco guitar. It is slightly less effective in rasgueados than my good flamencas. quote:

Any serious student of any instrument is aware of this effect. quote:

He would be disappointed to learn he has wasted his life playing the guitar the wrong way. quote:

I don't experience any of the problems they are said to cure. It would just get in the way of classical technique, and it would make either flamenco position impossible.. RNJ

Sorry Richard, but those who advocate this or that "ergonomic" sitting position, are usually the lucky ones never to have had any severe problems with guitar playing "for hours" as you say. My condition was not so, and guitar playing caused some changes in my body, which are only going to heal with lots of lots of muscle & flexibility training. There is no reason why there should be an ergonomic position for each individual. Sure everyone can find "his" optimum position, but whether this will or will not cause any health problems, we simply dont know that. Hence, in conclusion, i do not understand many of the negative opinions towards these gadgets, since they are just a tool, just as a footstool, or tabs or tuner or machine heads are. It seems that people project their whatever positive experience upon others, ignoring that we all have different physical conditions from which we depart on. FYI i do not use or advocate these rests or whatever (sometimes i use a footstool sometimes not), but i dont have a reason to assume that they are useless, just because I do not need them. In fact i dont even know if they are useful at all, it is up to everyone to decide for themselves, and only for themselves.
