Thanks for the comment Rainer
You without nails, the only nail used is that of the very short thumb, majoring in playing the classical / romantic music is philologically correct or without fingernail or with very little fingernail.
The fingertip with practice hardens and forms a callus which allows to run smoothly the performance practice of the time (1800) without in any way preclude the technical fluency, indeed, you can find new colors and shades, with the use of nails can not be achieved.
Using gut strings you are forced to play without nails, if you use a fingernail after ten minutes the nail flakes with disastrous consequences.
