I got sound after a few minutes of increasingly frantic trying. I got actual notes some time later. Decent-sounding notes took a little longer. Decent-sounding notes in a phrase took a lot longer, but I was starting from scratch.
Frailty isn’t going to be a problem, unless you mean that you’re so weak you won’t be able to hold the flute up very long. (Take up weight lifting!) My Clarke whistle takes more air than my flutes. It’s not the volume of air you put into it, but whether the air stream is focused and directed properly.
I’m thinking that it will take me a life-time even.
That’s a good thing, isn’t it?
I’ve heard some people playing in a session and they don’t have a decent sound coming out the wooden flute and their phrasing is lousy. That worries me.
It shouldn’t worry you. If you already know you want to achieve better than that, then you are halfway to your goal because you have a clear picture of what you need to do.
It’s the people who think they sound great after only a month who need to worry.
