Right hand stability

Never use a metronome. And practise on a real piano.

Hanon #1 at 65 bpm Hanon #1 at 76 bpm and the movement from Clementi's Sonatina The reactions are quite visible in the Hanon drills. The problem with the 2nd finger ... about which I was initially talking about can be seen in the Sonatina...just before the end...somewhere in the final phrase...there is consistent pause...gap...whatever... Just after recording these videos I experienced somekind of regress in the sense that I could barely play the Hanon at 52 and even at that tempo there were still gaps when the RH 2nd finger came into action. I don't even have to mention that I can't play the sonatina anymore at the tempo at which I was able to play it in the video. That determined me to post here. After Alan's response I stopped using the metro and things improved. I applied his philosophy "no down only up" and the 2nd finger got better. However there is no way near so much stability as it is in my left hand. It seems that my left hand is functioning by itself. The more I activate my fingers the more I perceive this problem. Since I started practicing without a metronome I managed to adjust the finger actions. I would dare to say that now the finger action stops (but remains active) when the key reaches the keybed. Moreover I removed almost completely that "false feeling of gravity" at slow tempos. It's extraordinary how much the arm tried "to dig in" instead of letting the fingers do their job. A while ago I thought the problem was over but the more I concentrate myself on the finger action the more I discover that there is still unwanted tension to remove. Did you have any luck with the straighter finger path? Just had a look at the Hanon film. I can see that the right hand fingers are slipping very notably. I think that not only does this destabilise the arm, but adds a lot of complexity to the movement. The fingers are forced to time the stopping of their activity- in order to avoid continuing to slip back across the keys. I think this prevents the quality of stabilising contact, after the keys have sounded- leading to a kind of constant on/off feeling that leaves the hand in all kinds of different states that are hard to predict, with the arm having to make various compensations. With a direct line, it should be possible to get into a much more predictable position of stability, without the finger having to abruptly stop itself.
