Trying to add in the metronome while playing the piano ...
And do not try to add the metronome to a piece already learned
That's exactly what I was trying to do, taking suggestion to learn metronome too literally... Thank you for pointing this out this clearly!
You are welcome.
Bottom line is that you want to develop your ability to hear and feel the groove, the rhythm, the tempo. So learn that away
from the piano, which is much much more doable than:
1. Trying to play the piano while distracted by trying to hear the metronome.
2. Trying to hear the metronome / learn the groove while applying the metronome beat to a piece that most likely you have learned a rhythm/ tempo different than the metronome.
3. Trying to hear the metronome / learn the groove while applying the metronome beat to a piece that most likely more complicated than a very simple one note/one hand piece.
4. Worrying about not being able to do it.
5. etc, etc, etc.
Bottom line: keep it simple...focus on what you want to do in its most essential basic form
, (to hear and feel the beat), and only then, when that skill has had some time to develop and mature in your brain, apply it to some very simple music (one hand, one note per beat).
