Big Words (134): "甜美的"歌声

1. silver laughter 银铃般的笑声，好直接的翻译，

2. musical→containing or constituting or characterized by pleasing melody. 强调韵律感，

3. euphonious→①having a pleasant sound.

②(of speech or dialect) pleasing in sound; not harsh or strident.

4. dulcet→extremely pleasant in a gentle way；pleasing to the ear.

看英英解释，euphonious、dulcet与mellifluous差别好像不大，

mellifluous正好可以分解各通melli和flow，将甜美和流畅的意思都包含进去，
