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 〜
