Hello Kai,I have watched this video https://learn.flamencoexplained.com/technique/videos/thumb
First of all, thank you for the video!
I have 2 questions:
1. When you go down it looks like you don't make any adjustments, how is it possible? Every time I go down I land on the flesh of thumb so I have to move a little bit forward to hit the next string with my nail.
2. Many flamenco players put their thumb in almost 90 degrees angle to the string and it makes sense since this part has a longer fingernail but it seems that you keep the thumb in the same angle and catch the string with the side of your thumb where the fingernail is shorter and harder to catch the string with, even in alzapua. Is it subject to individual preference?
Thank you!
