Playing the piano with both hands, a simple exercise

Some hints:


Bass is into rhythm (rhythm section). So it may be worth thinking the bass while playing.


One can try for example the classic French song, La Mer.
Playing deep bass melody...
Do
La
Fa
Sol
and repeat in loop...
Counting 4 1/4s or 2 1/2s for each note.
The adding the melody with right hand.
If left hand fails to keep up with groove an exercise is to try, Do, La, Fa, Sol ie C A F G in loop while playing with the right hand moving it around, touching objects, writting with pen on paper etc while left hand plays in rhythm. A similar exercise may be often done by orchestra conductors for the purpose of obtaining independant movement of each hand.
