Where I live, we are now entering the hottest part of the summer. In these times the two great contrasts are heat and coolness, and each gives meaning to the other.
In old hokku, the moon at night was always seen as a cool contrast to the heat of sun in the day. But coolness may also be expressed by sound, and when we have sound added to sight, that enhances the cool sensation, as we see in this old hokku by Fuseki:
Tsuki suzushi uma arai iru kawa no oto
moon cool horse wash-is river ‘s sound
We may loosely translate it in daoku form as:
The sound of horses
Bathing in the river.
It is very objective and clear, giving us only the essence of the scene/event, without any comment or opinion — any “thinking” — added by the writer; and that is the definition of daoku — objective hokku.
