One thing I remember studying in Japanese is the usage of Japanese Sound Symbolism.
Japanese has an unique sound system to mimic and illustrate various situations and object sounds. Similar to English sound words; Bang, Wham, Zap for example.
doki doki [suru] a throbbing heart
shiin to [suru] [be (lit. do)] quiet [sound that portray silence]
(suru not optional)
Wiki Japanese Sound Symbolism
I would like to use different languages sound symbolism words to add a secondary level of audio texture to the final piece. I hope by adding the cultural sounds, it would add additional sound uniqueness and richness to each segment of the poem.
