The trill you are asking about in your post is played as illustrated below - a) or b). It requires you to play the d using the zither ring and immediately after bring your thumb down fast and forcefully onto the e to make it sound by this action, and then quickly withdraw (not lift off!) the thumb a...

Hi Andy I am pleased to read that you found my photos helpful, and I am sure that with your determination and dedication you will soon get to grips (pun intended) with the strings. Sitting higher, as well as keeping your wrists up, will help. And yes, I did notice that you now have full control of t...

Hello all Things are pretty grim here in lockdown in the UK as well. Regarding your question, Andy: I've had a look at the Stretta Noten website, as they commonly show a sample page of the music they are selling, and the "Leichte Stückl" series has 1. and 2.
