The fair breeze blew,the white foam flew, the furrow followed free:we were the first that ever burst into that silent sea.

The Meaning:So the meaning of this is that this was straight after the ancient mariner killed the albatross,that it was a quiet night and the breeze was all they could hear and the meaning of the burst into the silent sea that the albatross was the first thing to fall into the silent sea.

The Rhythm/iambic pentameter:The fair breeze flew the white foam flew and the rhythm in that is blew and flew because they have the same ending which brings in the iambic meter because if you put a simple beat while saying the poem with the rhythm.

Alliteration:The example is furrow followed free because they all start with f and the effect of that causes the reader to keep entertained as well as to keep the iambic meter going also.
