At first he did not like to practice that much, but his father was very strict. In 1974, when he became a student of the Music High School and the Academy of Music, he began to play in the School and Academy Symphony Orchestras. He liked being able to perform at the student concerts which were held regularly in the famous "Golden Hall" of the Musikverein. He enjoyed performing so much that he decided to become a professional musician like his father, the concert master of the Vienna Symphony Orchestra. This formerly quite lazy boy found his real interest and love in music.

1974-1978 he studied violin and viola at the Music Academy/University of Vienna with Prof. Sivo and Prof. Führlinger. His life as a professional musician started already at the age of 16, when he received his first contracts with the legendary Waltz Orchestra at the Stadtpark and the renowned Operetta Orchestras of Baden and Bad Ischl. He also was active in several other ensembles, mostly in leading positions.

In 1977 the famous violinist Albert Kocsis invited Laszlo Barki to perform with the Cologne Chamber Solioists - Orchestra and introduced him to Prof. Max Rostal.

At a recital in 1981, the renowned former president of the Vienna Philharmonic, Prof. Otto Strasser, heard him play and promised to recommend him to that famous orchestra. Soon later, a dream became true, when the Vienna State Opera and Philharmonic Orchestra invited him for an audition!
