I’m guessing you haven’t thought much about this, but one of the things we musicians have to put up with is calluses. Not feeling sympathetic? But what if the calluses are peeling, or bleeding, or have bruises under or around them, or make you look like you’ve been attacked by a vampire? You can probably guess that string players have calluses on the tips of the fingers of their left hands, and you’ve seen the indelible marks on the necks of violinists and violists.
