Clementi - Sonatina In C Major Op.36

Here is the 1st movement. Though it has some flaws and rhytmic problems...

I enjoyed your performance here. I recently got interested in Clementi, so I don't have a great deal of experience with his music, but it seems to me that the difficulties are similar to Mozart - both utilise fairly sparse accompaniment textures, so everything is very exposed. Generating a strong sense of pulse without overdoing it is not easy. However, the one thing for me that was fairly noticeable was that the bass was overpowering the melody in some sections. Maybe because it has fairly little to do it is harder to control, or maybe it was due to the placement of the recording device nearer to the bass end of the piano. I think if you sorted that out then you'd have a nice clarity throughout.

Unfortunately all of my recordings show lack of adequate counterweight from the arm. This is why most of the times the keys are not fully pressed or they are pressed but do not remain in contact with the keybed as long as the note should last. This is also why when I generate a too strong and sudden action in my fingers the hand starts to "hop". One can see this easily in this video. I wonder how could I solve this problem...
