I play the piano. And I am newly starting to learn guitar on a classical one. I want to play electric guitar after I improve and manage to acquire one.
I wanted to play the guitar left handed, with my right hand on the frets. But I am a right handed person. Today the guitar started to kind of feel right (I mean ok) in this lefty position. The reason I do this is to have develop my left sidedness both muscularly and cognitively, and also have a unique feeling about my guitar playing, and also I have a weakness on my right hand and some right body muscles a bit so I want to develop it. After some practice on guitar as lefty I even feel my right hand has become more dexterous on piano keyboard, which also suffers from the general right side weakness in my body. Normally on piano keyboard I feel my right hand a bit stiffer and less dexterous than my left hand. I also hold the pen with my right hand.
I feel ok with practicing guitar left handed but my only concern is that my right hand is my melody hand in the piano, and to have a nicer piano tone my right finger tips should not get hard or callused by time after pressing the strings on the frets.
Is it a permanent or temporary thing to have this hardness on the fingertips of the string pressing fingers in guitar or other stringed instruments like violin, cello etc.?
