Pretty soon he could play reveille, mess call, and taps.

很快，他就能吹奏起床号，就寝号，还有熄灯号了。

Who put the reveille cannon on top of the Clock Tower?

谁将起床号大炮放到了钟塔顶上？

Then he'd put on his things, climb onto the flat rock, and blow reveille.

然后他挂上他那些东西，爬到那块平坦的岩石上，吹起了起床号。

I listen vainly, but with thirsty ear, for the witching melody of faint bugles blowing reveille, of far drums beating the long roll.

我用饥渴的耳朵倾听着，但是已经听不见军号隐约吹出的起床号那迷人的曲调，听不见遥远的战鼓发出震耳的长鸣。
