| + | * 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. | ||
