Eduard Rappoldi studied composition and music theory under Simon Sechter during the later period of his musical education. Although the article does not give precise dates, it clearly states that after his early training in violin and his formal studies in Vienna, Rappoldi later undertook advanced theoretical studies with Sechter, who was a renowned Austrian music theorist and educator based in Vienna.
This student–teacher relationship placed Rappoldi in contact with one of the most influential theoreticians of the nineteenth century, known for his strict pedagogical style and extensive work in counterpoint. Studying under Sechter would have provided Rappoldi with a solid grounding in compositional technique, complementing his career as a violinist, conductor, and composer.
