treetops, twig
梢 centers on the thin, outermost ends of a tree: the treetops and the small twigs that grow there.
梢 combines 木 (tree) with 肖, which likely contributes the sound and the idea of something small or tapering, together suggesting the thin tips of branches.
The tree 木 on the left and 肖 on the right look like a tree with small, pointed twigs at the top. Picture the treetop where the smallest branches spread out.
For ショウ, imagine a show of treetops swaying in the wind: show -> ショウ, and the treetops put on a graceful show.
