Hi Derek,
I believe this re-recording of the first movement is quite good! A couple of thoughts: First, in taking those loud chords in the LH--to avoid harshness, rather than striking them from above, try sinking into them with relaxed arm weight instead. You'll find it will render a richer and more musical sound. Right now those chords sound somewhat forced.
Secondly on the use of the metronome, it does have some valuable uses. For example, 1) you can straighten out a tricky rhythm in a passage with it. 2) You can use it to get an idea of the tempo. 3) After sufficient practice one can play through the entire piece with the metronome to take a measure of security in playing. If snafus occur along the way, bracket those with a pencil for intensive practice afterward. You see, whenever we approach a difficult spot, the tendency is to slow down slightly in order to accommodate the problem; however, in doing so--and we might not even notice the slowing--we can fool ourselves into thinking that the piece is playable. That's when the metronome informs us otherwise. So it's a way of smoothing out the long, continuous line of the music. 4) Finally, another great use of the metronome is to increase speed over time to get the piece up to desired tempo. To do this, we play the piece each time by adjusting the speed upward by only a couple of notches or so. The gradualism fools the brain, that is, the increase is so nearly imperceptible, that the brain isn't really conscious of what we're doing. Along the way, if a few of those rough spots rise up again, then they get intensive therapy yet again. If we make a lot of mistakes, that's a signal that we've exceeded our current speed limitation and need to drop the speed downward to meet our capabilities at that point. Then we repeat the process to increase the speed on another day.
But now having said all that, here's the important point: We should use the metronome to accomplish specific tasks, but once we succeed, it should be turned off immediately. The less we have to play with the metronome, our playing will be less robotic. That is, it will have a better natural flow and fluency. So the metronome has to be used only for the exceptions, not as a general rule.
I hope this is helpful. Keep up the good work! I'm glad to see you posting here.
