日本の学校でよく使われるチャイムの音。
A chime sound commonly used in Japanese schools.
同じ楽器を鳴らしている音だが、それぞれ音階が違う。
日本語のオノマトペは音の高低、太いかどうかで表す文字が違うので、チャイムの音もこのように表記される。
They are sounds of the same instrument, but each has a different scale.
Japanese onomatopoeia is represented by different characters depending on whether the sound is high, low, or thick, so the chime sound is also written in this way.
