Commentary
Book One Spring Poems I 17

Headnote: from the time when he presented a hundred-poem sequence.
Here begins a run of poems on the warbler. This one catches the moment when ice in a valley stream has broken and the water has begun to sound, and waits on that sound for the bird's voice to follow. The headnote refers to the hundred poems presented to Retired Emperor Go-Toba, the Shoji sequences of 1200.
Fujiwara no Ietaka (1158-1237), a son of Fujiwara no Mitsutaka, studied poetry under Fujiwara no Shunzei. He was one of the compilers of the Shin Kokin Wakashu and is spoken of alongside Teika. He is remembered for continuing to exchange poems with Go-Toba even after the Jokyu disturbance.
The season is early spring; the place is a stream in a mountain valley.
The occasion was the presentation of the hundred-poem sequence.
Forty-three of Ietaka's poems entered the Shin Kokin Wakashu.

The first two lines describe waves that have broken out through the ice of a valley stream. The phrasing follows a poem in the Kokin Wakashu in which waves appearing through the gaps of thawing ice are seen as the first blossoms of spring.
A perfect auxiliary in the third line states flatly that the sound has been made. The particle carries the sense of even the waves, implying something that has not yet spoken: the warbler of the lines below.
The fourth line is an imperative, and the poem turns on it. Description gives way to direct address, and the waiting comes to the front.
The poem closes on a noun, so that the one addressed is named only afterwards, in inversion. Water sounds first, and the bird's voice, still unheard, is entrusted to the wind; the whole poem is organised around hearing.
