Home is quiet & audible the sound well
Usually I don't notice the difference of sounds.
But in quiet place, it's obvious.
Karim Nagi teacher uses 5sounds in finger cymbals.
Open ,close, vertical A ,vertical B, and circle .
For me A&B is same so far. but it's not same!
Also big sound & small sound ‥ it's very important. To use the difference, it relate ” with heart❤️ ” or ”no heart💔”.
It's not easy 〜
