In music, mi is a singing-name for a note. When you climb the scale as do, re, mi, fa, so, la, ti, do, mi is the third step. Teachers like these little names because you can sing a tune without stopping to say letter-names like C or E.

In music在音樂裡， mi is是 for a note給音符用的 a singing-name一個唱名。 When you climb the scale當你爬音階 as do, re, mi, fa, so, la, ti, do唱成 do、re、mi、fa、so、la、ti、do 的時候， mi is是 the third step第三階。 Teachers老師 like these little names喜歡這些小名字， because因為 you can你可以 sing a tune唱一段旋律， without stopping to say不必停下來說 letter-names like C or E像 C 或 E 這種字母名。

Though actually, countries do not all mean the same pitch by mi. In a “movable do” class, mi is simply the third step of whatever scale you are in. In a “fixed do” class — the kind many music students in Taiwan meet — do is always C, and mi is always the note E. Same word, two maps.

Though actually不過其實， countries各個國家 by mi說 mi 的時候 do not all mean指的並不都是 the same pitch同一個音高。 In a “movable do” class在「首調」的課堂上， mi is simply就只是 of whatever scale you are in你當下那個音階的 the third step第三階。 In a “fixed do” class在「固定調」的課堂上 — the kind many music students in Taiwan meet台灣很多音樂學生遇到的就是這種 — do is always Cdo 永遠是 C， and mi is always the note E而 mi 永遠是 E 這個音。 Same word同一個字， two maps兩張地圖。

The name is very old. Singing teachers once used a Latin hymn to remember the scale; mi was cut from mira, a word in that hymn meaning wonders or miracles.

The name這個名字 is very old非常老。 Singing teachers聲樂老師 once曾經 used a Latin hymn用一首拉丁聖歌 to remember the scale來記音階； mi was cut from是從…剪下來的 mira這個 mira， a word in that hymn那首歌裡的一個字， meaning意思是 wonders or miracles奇事或奇蹟。

It is a classroom and choir word, not a fancy one.

It它 is a classroom and choir word是課堂和合唱團的字， not a fancy one不是什麼高級字。
