I am playing the piano and I have started to learn guitar.
I had asked a similar question asked from the guitar perspective on this site.
Do calloused fingertips (due to playing guitar fretboard fingers get calloused) negatively affect the piano playing? That can be sensitivity of fingers to the touch, tone quality, piano-forte, crescendo diminuendo quality etc.
Does this concern has any foundation? I wonder should I be concerned about this at all.
