Acoustic Tohaina (DAS)
Kupu Whakataki
Te tukanga inenga DAS: ka tukuna e te taiaho nga pupuhi marama ki te taha o te muka, a ka raru etahi rama ki te rama mai i te ahua o te marara ki muri i roto i te pupuhi. I muri i te whakaatatanga o te rama pokanoa ki muri, ka hoki mai te rama pokanoa whakamuri ki te taputapu tukatuka tohu, ka kawea te tohu oro wiri i te muka ki te taputapu tukatuka tohu. I te mea ka noho tonu te tere o te marama, ka taea te ine i te wiri oro mo ia mita o te muka.
