One of his biggest accomplishments – apart from educating several talented young musicians – was when the world-famous Yehudi Menuhin wrote a recommendation for his music sheet titled Hegedű ABC (Violin Alphabet).
In 2003, following the initiative of Vilmos Oláh, one of his outstanding students, a newly founded music school in Bangkok was named after him. This is the Dénes International Music Academy, where a Hungarian musical curriculum is being used.
Mr. Dénes has always assumed an active role in the work and management of the National Music Teachers' Department and the Hungarian Music Teachers Association.
