1-3 is awkward for me.
Outln, I have a weird thumb as well, but in the opposite way of you - it hyperextends at the tip from the joint. It drives my teacher crazy because she thinks I am flexing it wrong. I keep telling her that to me it feels totally natural. It weirds her out so much that she hates giving me fast pieces to practice since "the thumb will just get in the way."Though that might be the reason that thumb trills feel uncomfortable, my hyperextension is getting in the way if I don't concentrate.
Your teacher isn't wrong. When your thumb is hyperextended, it adds a lot of tension to the thumb under technique. Try it. It's much easier to bend your thumb when you move your thumb under your fingers than to keep it hyper-extended. Essentially, your thumb does get in the way when you do thumb under.
I can't agree at all. I wouldn't say never move a bent thumb under, but it easily causes a sense of tightening all over the place- if you bend it for the sake of doing so. It easily isolates the thumb too much. When the thumb stays naturally quite straight (neither willfully bent nor extended until it sounds the key), it helps you ensure that the arm is carrying it across adequately- without tightness in the thumb.
I'm the guy with the hyperextended thumb. I think werq34ac and nyiregyhazi are both kinda right. Yes my thumb does get in the way on fast, "thumb under" passages as my teacher and werq say. it gets in the way because it's natural, resting position is hyperextended. I have to flex or tense my thumb to get it into nearly everybody's normal thumb position. And that is where nyiregyhazi is kinda right - that when I have to bend it to "normal", it causes tension. The hyperextension is totally tension-free - that is just the way it rests. And when it is hyperextended I sometimes have to compensate with my wrist to twist the thumb-pad to hit only one key. Argghh! But yes my teacher is correct that when I have a loose "compact" hand (figures bent on the keys, the thumb oriented towards the palm of my hand), things can get a lot easier. The problem is that I have to teach my hand to do what comes naturally to other people!Enough about my weird hand - back to trills! And yes my preferred 3-4 trill does come from the wrist rotation, not just the fingers. I only really could do trills once I learned how to loosen up and "shake" my wrist when needed.
nyiregyhazi: The joint goes back away from the hand. Most people's are straight when extending the hand muscles - my thumb joint naturally bends at the top joint so the thumb hyperextends even more. I need to explicitly engage muscles in my thumb/hand to keep the thumb straight when flexing my hand. Here are pictures. The first one is my hand resting on the keys with my hand muscles slightly opened. The second one is the same, but consciously having to straighten my thumb.I think it is evident that the second picture is what should happen for better technique, but it one that takes introduces a small amount tension compared to my "default" position.Sorry for the trill hijack - it is tangentially related since it does affect my thumb trills!
ah I used the wrong word. I don't mean bent, i mean non-hyper-extended. Hyperextending by its definition means that you are using extra muscles (hyper and extending). The thumb should be generally straight or somewhat close to straight. Anything else impedes the up and down movement we use to actually play the key with our thumb.
Looking at the pictures, I feel 99% sure that it's actually the severe bend in the joint closer to the hand that you should be concerned by- rather than by the extension in the end of your thumb.
That is how mine is, even worse than his I think. The bent in the joint is not something I do, it is there naturally when my hand is relaxed. When I try to open my thumb or lengthen it the joint collapses even more. With my left hand the thumb is more flexible and I can now almost lengthen it straight (but not perfectly, the bent is always there). In my right hand I can see some tendons in my palm, which seem to be too short and are pulling the joint. I have been trying to find muscles that I could strech to get the thumb more open, but stretching exercises tend to just cramp the hand more.
Can you do the one like example 8 here?&feature=relmfu
If your thumb just doesn't go any straighter after a certain point, it may not necessarily matter if you're completely straightened though. The big issue would be whether the joint is bent due to lack of activity/unnoticed inward gripping, or whether it's bent because it simply doesn't extend any further than where it is. If it's the latter, it could still be relatively stable.
I don't think my thumb is unstable these days, maybe it was in the beginning. Even if bent it works fine as long as I don't need to do larger than 7ths. I don't have trouble with scales either.
Thanks, nyiregyhazi for the in depth analysis. I've been concentrating on the top joint because I've been aware of its being different for all my life - but I haven't been aware of the other problems. I can't see the youtube videos right now (blocked at work ), but when I get home I look forward to viewing them.As far as Feldenkrais, I'm very familiar with the method as it solved some issues I had in my running form! Right now I'm discovering more things about how my thumb moves than I knew before - I'll be working with thinking how it can move longer rather than straighter. Thanks again - and glad to see that outin is getting some illumination as well.
Since we already hijacked this thread with our thumbs, I'll post photos of mine.Here's my left (better) thumb when the hand is streched to the max:And here's the right hand trying to do the same:The problem I have with right hand octaves is that when I play higher on the keys, the part marked with a red dot presses the key next to the lower note:If I could flex the nail joint it would not, but I cannot flex the joint at all when the thumb is extended this far.
I notice that the arch position is severely collapsed- not only in the outstretched photo but also in the regular one. When the thumb is out to the side like this (without first going down and under the hand more), many muscles have to work extremely hard to keep you stable. When the thumb goes more "under" the hand (opening a wide space between the thumb and the knuckle) there's a very simple opening activity that provides all the stabilisation you need.
THe old russian trick to illustrate this is to rest on a surface with the hand open and then press on the knuckle. It can take phenomenal pressure- but a simple and relatively low effort is enough to keep stable. If you do the same with the thumb and knuckles at a relatively similar height, it take phenomenal effort and it's still almost impossible to remain stable. Only when the space is truly opened is stability a simple thing to get. I can't say anything for certain obviously, but I do suspect that there might be room for improvement if you experiment with getting more space in the arch- so the the thumb is contacting the key right on its side, rather than halfway.
I don't think I explained myself very well. I can play an octave anywhere with my left hand. I can also play it slowly with my right at the edge of the keys.
Can't you play with the thumb from above? Like the hand is high and the thumb is in an angle of about 45° (or even more) ascending from the key to the hand?
As I recall, Cziffra had a slight bend that never went away 100%, but he didn't allow himself to get into awkward positions as a result of it- due to the use of the wide space between thumb and second. He had a way of moving that always seems to be minimising it, rather than encouraging it to happen more.
