How do yo make online lessons work?
This is a good question. The reality is that online lessons are different from in person lessons. And that's okay. For my students, the main goal while teaching online lessons is for students to have a positive experience, and to enjoy music making; to have little to no interruption in their practice routine and momentum, and to stay connected with already established practices and activities (preparing for youth orchestra, future concerts, etc.) as possible.
The pace and style of lessons really has changed quite a bit during this period of our "collective stay-at-home" and "distance existence". As a teacher, this stay at home period has been a time of new beginnings, which includes updating the way that I teach in terms of activities and interactions which are better suited for the "big screen" and that foster student engagement and success with online learning for my students. For younger students in my studio, it has been a time where we have shortened the duration of specific areas of focus, and increased the frequency of smaller chunks of material and activities. Older students have had changes to varying degrees as suites their individual needs.
My violin teacher told me that I have to clip my nails because they are too long. Do I have to cut my nails?
Well, I do not know how long your finger nails (I am assuming we are discussing finger nails) actually are at this point. However, in general, you must keep your finger nails of the left hand short enough to fully get the benefit of your finger pads when vibrating. You also need the nails short enough to have your left hand fingers at the correct angle. The short answer is that violinists (and violists, cellists, etc.) must make the sacrifice of safely short finger nails (at least in the left hand).
