In the analysis of a poem's rhyme scheme, the lines of the following stanza — 'The eagle soars above the hill (A) / And surveys the land below (B) / The rivers run against their will (A) / Through valleys cold with snow (B)' — follow the pattern

In this stanza, 'hill' (line 1) rhymes with 'will' (line 3), and 'below' (line 2) rhymes with 'snow' (line 4). This alternating rhyme pattern — where the first line rhymes with the third and the second with the fourth — is designated ABAB. AABB would require consecutive lines to rhyme; ABBA would require lines 1 and 4 to rhyme with lines 2 and 3 rhyming internally.
