Long ago, (longer than I care to admit ) I was taught about the proper formation of the left-hand claw and the use of the fingertips as the "proper" technique. Of course, in the real world of playing, these things are often matters of degree and we all form our own habits and variations. I'm curious as to how many players here, in actual practice, curve the fingers of the left hand such that when a note is stopped, the higher strings are free to ring unimpeded. For example, when you stop the C# in first position (ala Simandl) on the A string with four fingers, are the D and G strings free to ring? That is, are the fingers of your left hand touching those strings?
