Rhyme involves repetition of the final sounds of words: fish/wish, moon/June, etc. Consonance is repetition of consonant sounds as in pitter/patter or strong/string. Assonance is repetition of vowel sounds: rumbling/thunder, gray/bare, and so on.
How to remember the term "assonance"? Just think of that crude measure of class attendance: Cheeks in Seats!
