How does Li-Young Lee use imagery in Early in the Morning?

Lee describes his memory of his mother combing her hair by using a detailed set of images. These images include: "the music of comb / against hair": sound; "salted Winter Vegetable": taste; "black as calligrapher's ink": sight; "my mother glides an ivory comb / through her hair": touch. Images, such as the latter, can also be dynamic; that is, they can describe actions.
