My first post:
I have found an interesting harmonica here. So, I tried to know more about harmonica.
And, I have read this article , in which the author doesn't mention the physical calculation, which makes a harmonica to be played with a full-octave.
Now, I want to know about the physical calculation in diatonic harmonica. So, my question is: Is there any physical calculation which allow a harmonica can make some different sounds?.
I care about a full-octave only; such as, 8 notes: C6 - D6 - E6 - F6 - G6 - A6 - B6 - B7.
My second post:
After a short time of waiting, there is an answer for my question. In this answer, there is a function:
f=(nv)/(2L). And, he said: "The frequency that is produced in any open tube depends on length".
I don't know the length what is: length of reed, or length of tube; or, both of them. Could you explain it for me, please?
