What's the story behind this character 频? Neither of its components contribute phonetically to it, yet I can't seem to relate any of its components 步 steps and head/face 页 to its meaning of frequent/repeated.
「頻」 was created from omitting 「氵・水」 from 「瀕・𩕨」. While 「瀕」 remained as a character used for its original meaning, the newly created 「頻」 was used as a phonetic loan meaning frequent.
「頻」 was originally 「瀕」 (riverbank), comprised of semantic 「涉」 (picture of feet/footprints next to a body of water > to wade across water) and semantic 「頁」 (picture of a person with an exaggerated head/eye).
The 「水」 part of 「涉」 was often written in the middle of 「步」, leading to the side-by-side structure 「⿰𣥿頁」 instead.
The side-by-side structure was prone to corruption. More specifically, 「水」 tended to be squeezed out and omitted, forming 「頻」.
From this, we can see that 「頻」 is just a shape variant of 「瀕」, and originally shared the same definition as 「瀕」. From the Classic of Poetry: Major Court Hymns: Decade of Dàng:
A pool becomes dry; is it not because no water comes to it from its banks?
A spring becomes dry; is it not because no water rises in it from itself?
Great is the injury [all about]. So that my anxious sorrow is increased. Will not calamity light on my person?
Later on, while 「瀕」 remained in use as a character representing the word meaning riverbank, the differentiated character 「頻」 started becoming solely used as a phonetic loan character meaning frequent.
