What is a whistle?、That's right。It has been several decades since this was considered a musical instrument.。Since then, I have started playing steel pans.、Many things can be used as musical instruments、The whistle is perhaps the simplest example.。Almost like a whistle (originally a bird's voice)。
Whistle also has another meaning。Moreover, it is a “command form” that means “find the source of the sound” = “pay attention”.。It's a pretty harsh sound though、(often) alerts you that you are in danger、The social impact of “good intentions” being “jarring”、Intuitive understanding is established、This is a rare example。
A sense that combines this with "music"、I am once again impressed。that the senses are flexible。It's impossible as long as you live in Japanese society.、I think (almost without basis)。
