Lyric

When Yamaha asked to create an artistic song that would take advantage of the new AI singing voice synthesis technology, composer TAMAWARI Hiroshi chose "Irohauta" for the lyrics. Irohauta, a symbol of all things in nature and our emotions that can be written in Japanese, is expressed with heavy orchestral music and a chorus of six voices.

Irohauta is a traditional Japanese poem of unknown authorship, a 47-character pangram composed without duplicating kana characters.
Irohauta has been used for more than 1,000 years to teach children the first letters of the Japanese alphabet, but its meaning is far from being suitable for children; it is philosophical and Buddhist.

i ro ha ni ho he to chi ri nu ru wo
wa ka yo ta re so tsu ne na ra mu
u i no o ku ya ma ke fu ko e te
a sa ki yu me mi shi we hi mo se su n

An example of a modern translation
"iro"(=visible world, our body and flowers) bloom but soon fall away
In our world, no one can stay unchanged.
Today, beyond the depths of the realities of the world.
Don't dream shallow dreams, and don't get drunk on them.

In Japan, there is a word called "Kotodama," which means "spirit of words". Words have a soul of their own. Could it be that the words sung by a lifeless program also have a soul? Perhaps, Maybe in Japan.
