He had his first music lesson in harmony and piano with a friend of Wagner's, Dimitrios Lalas.
He studied form, instrumental and fugue with Walburnn, piano with Mayer-Schrey and choral singing with Becht and Stitch.
This was when he started appearing as the composer Riadis because he took the ending of his mother's maiden name, which was Elefteriadis.
He was temporarily arrested at the beginning of World War I and resulted to his permanent move back to Thessaloniki.
His songs were "distinguished by an expressive melodic line, somewhat oriental in its intervallic pattern; his harmonization’s are in the French manner".
