4.10Left hand and right hand can divide the chord
Once your left hand is playing the root, your right hand does not always need the root too.
For example:
Left hand:
C
Right hand:
E–G
That still clearly sounds like C major.
For Am:
Left hand:
A
Right hand:
C–E
For F:
Left hand:
F
Right hand:
A–C
This simplifies your voicings.
It also avoids muddy low-register chords.
