Beethoven wrote in an 1817 letter that he wanted to drop musical terms like " allegro" for fast, " andante" for slow, or " presto" for extremely fast.

贝多芬在1817年一封信中写道，他想删除一些音术语，如板曲、行板曲或极急板曲。

So, things like allegro, allegretto, crescendo, diminuendo are all Italian words, which musicians understand, even though they're not in their own language.

所以， 像 Allegro（板）、Allegretto（小板）、Crescendo（渐强）、Diminuendo（渐弱）这样术语都是意大利语词汇，尽管它们不是音家自己语言， 但他们都能理解。
