Schweik/21 Jul 12 - 09:23 AM "we must agree to disagree" RE: Must we?? Sorry hearing you say so. There are moments in life when it may be more fruitful to learn than to disagree... Concerning strength: Strength no 1) (maximal power).The maximal pressing power usually is (surprisingly) equal for all fingers.Test it if you are curious and you probably will find something like 3-10000grams for all of them (if you are not very athletic). Strength no 2) (endurance) You may perform a power of ca 10% of your maximal power for a longer period without getting strain problems and accumulation of waste products. To execute static or repetitive finger pressing movements as with concertina playing you need a force of 100gram or usually less (button pressure usually is 50-80g) while your capacity according to the above is expected to be 300+grams (10%) Consequently you can expect NO need for additional "strength" Now to widen the perspective a little I can admit that IF your aim is extreme performance, like playing extremely fast and for extremely long periods without any break, or setting some World Record, there will probably be some advantage for the "stronger" individual.I willingly "agree" on that point Concerning coordination: The 3rd finger/ring finger can NEVER get the same capacity as the others ( even if having equal strength) since it is tied up by connective tissue links to the tendons for 2nd and 4th finger.The related disability can NOT be eliminated by training.Maybe by surgical invervention but that is hazardous and maybe the nervous function will not be good enough anyway.Possibly there are individuals not having these tendon links by anomaly but I haven't seen it or heard about it.
