Khoury started a new phase in his life in 1989, not as a singer but as a keyboard player and a band conductor, and appeared on TV. He continued as a keyboard player until 1996, and played with many Lebanese artists. But during that period, Khoury wrote and sang the single, "Fik Yamma Balak" (فيك ياما بالك). It was released in 1994 and established him as a singer. In 1997, he wrote, composed and performed his second single "Lasbor Ala Welah" (لأصبر على ويله). It was not until 1999 that Khoury finally became known in the music industry as a writer/composer when he released two songs for Nawal Al Zoghbi, "Tia" (تيا) and "Dalouna" (الدّلعونه). In 2001, Khoury launched his first official album, "Khayal El-Omer" (خيَّال العمر), and the next year, Khoury shot his first video clip "Ya Shog" (يا شوق).
