I know that the metronome is a critical thing to consider to ensure coinciding with the tempo, especially in classical pieces (Mozart, Beethoven).
I have a problem that i cannot keep it up with this continuous endless line of beats so that i feel that the sound of the metronome drives me out of my concentration in playing the correct notes.
I have decided to depend on my listening sense to adjust the tempo, but of course that isn't a proper academical way.
