She put her lips together like a duck, And went into this to grab a buck, What do you call this face of such distaste, Or this money safekeeping place?

A voice of iron, cold and thin. I live one moment, sharp and bright, Then vanish like a soundless night. I'm not a word, yet I can speak I'm not a bell, but bells may seek my company in towers tall. What am I? Listen... that's my call.
