On this website, it says,
In elementary piano, the left hand (lower notes) typically plays chords, while the right hand plays the melody. If you're playing pop or rock and singing, you might want to play the chords with the right hand and the bass note of each chord with the left hand.
I've seen similar comments on other websites. When you're singing (or accompanying a singer), why is it more common to play the chords with the right hand? Is it so that the chords cover roughly the same range as the singing voice?
If that's the case, what would be the best thing to do when accompanying a singer with a deeper voice, e.g. covering roughly the range of the bass clef? If you also play the chords in the range of the bass clef, would you then play an even lower bass note with the left hand (which would make for some pretty messy sheet music), or would you switch hands and turn the bass line into something like a second melodic line played by the right hand in the range of the treble clef, above the melody sung by the singer?
On the other hand, if you stick with chords played by the right hand in the range of the treble clef and a bass line played by the left hand in the range of the bass clef, and if your bass line is a bit more melodic than just playing the bass or root note (which is more common in the case of inverted chords?) of each chord, is there a danger that this bass line will clash with the melody sung by a singer with a deeper voice?
