Before all, I have no issues about someone being left handed and playing a left handed instrument. I'm just curious about how the brain processes new skills. My question is: is there any issue related to effort, ability, technique, motor coordination... for a left handed person to learn playing the bass as a right handed one? I have always thought that because playing the bass requires strong abilities from either left and right hand, it will not matter if a left handed person starts playing as a right handed. The same thing would be if a right handed one starts playing as a left handed. Based on my thoughts, If someday I get a left handed student who wants to play the bass and he or she have never played a stringed musical instrument before, I can give him or her the option to play a left handed or a right handed instrument. Unfortunately, being a right handed person does not give me any experience to confidently advice someone about that. I have never had a left handed student and I would like to have some trustful source of information if someday I have to give some advice. I would love to have opinions, specially the contrary ones.
