    * note:
      * slow air blow, make the base frequency sound (lowest note of same shape opening)
      * fast air blow (faster enough to meet required speed), make octave higher note for the same shape opening
      * so if you blow fastest, you may reach even higher octave
      * a open hole make sound flow end exits early, and achieve a higher pitch sound compared to before
      * a half open hole make the effect of exiting less, and the pitch is inbetween close and full open
      * a hole near end tip more, make lower sound
      * a hole near mouse tip more, maker higher sound
      * slight shift hole towards end tip, make pitch slightly lower
      * a smaller hole also maker pitch slightly lower
      * with combination of techniques of adjust hole position and size, you can move the desired hole when design the recorder to hit the same note.
      * the back hole also help shift the note pitch.
