The singer and songwriter DDG (www.ddgmusic.com), refers to the expression "non-language" to define his musical stratagem, the escamotage that he uses in some of his songs to remove the language boundaries and give anyone in the world the chance to sing his melodies.
The non-language, mixing musical sounds, rhythms and melodies with no explicit meaning rather than words, is a way to gather and connect all the people around the world no matter what language they speak - Chinese, English, Russian, Spanish, French or Japanese - because anyone can use a non-language sound like "dondigitdigitdigitdondon".
from the song DIG IT a non-language example:
"We share the same sun
We share the same light
We share the same fight
We share the same rights
So many colours so many souls
Please save my brothers
And just sing and just sing the same song
Respect for people one dream just one love
So many reasons to believe and share the same goal
