Falsetto
This time it's about falsetto. This is not a normal use except when singing, but as you all know, it is a reversed voice. This is also known as Head Voice because it is usual to consciously give out as if it can resound to the tip of the head as shown in the figure. It is often used in chorus. When the mix voice described earlier can be done well, real voice - Mix Voice Falsetto and voice can turn out cleanly without turning over.
Whistle Voice
Finally it is about a whistle voice. I will not use almost anything here except singing. The point to be conscious is around the opening of the nape as shown in the figure, behind which goes through the falset. It opens the vocal cords compared to other things, shortens the part to breathe, so a high voice like a whistle comes out as its name. Also, here is very difficult to control the sound, it is still less if you search for songs using this.
