Quote #4
No Nightingale did ever chaunt
More welcome notes to weary bands
Of travellers in some shady haunt,
Among Arabian sands: (9-12)
The speaker really is at a loss for words. Well, not really, but he has a hard time describing the woman's song. All he really tells us is that it doesn't sound like any other songs he's ever heard.
Quote #5
A voice so thrilling ne'er was heard
In spring-time from the Cuckoo-bird,
Breaking the silence of the seas
Among the farthest Hebrides. (13-16)
The speaker does the same thing that he did in lines 9-12: tells that this woman's song is more thrilling than anything else anywhere ever. (Okay, he doesn't say it in those words but that's what he means.) The subtext is: you could travel to the ends of the earth (symbolized by the Hebrides) and not find anything so thrilling.
