Vander (his Kobaïan name is Zëbëhn Straïn dë Ğeuštaah) said in an interview that he invented Kobaïan for Magma because "French just wasn't expressive enough. Either for the story or for the sound of the music". He said that the language developed in parallel with the music, that sounds appeared as he was composing on a piano. Vander based Kobaïan in part on elements of Slavic and Germanic languages and in part on the scat-yodeling vocal style of American avant garde jazz singer Leon Thomas. The subsequent expansion of the language became a group effort, and as Magma's personnel changed, so new ideas were incorporated into the language (and the music).
