I want to play the flute again, and should I buy a used flute?

The more important question is which muscles are driving the diaphragm. Here is an exercise for you. You need to be flat on the floor.

Now put some books on your chest. As you breathe, are the books moving up and down? If the answer is yes, you are using the wrong muscles.

Keep trying again until your abdominal muscles are doing all the work, and those books on your chest are staying stationary. For just sitting around, your chest muscles do the job well enough. But for singing, you want to be using your abdominal muscles to drive your diaphragm.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
