Can someone me with the type of sound device, i think the first example from the poem is an alliteration and the third example a rhyme. not sure about the second one.

The first example is a Rhyme because Collar and Water rhyme together

The second example is Assonance

The third example is also Assonance but it might be Rhyme because air and there rhyme together
