Alexander Mikhailovich Zaslavsky studied under Konstantin Gorsky in Kharkov during his early musical education. The article on Gorsky notes that among his students at the Kharkov Music School was Alexander Zaslavsky, indicating a direct teacher–student relationship between the two musicians.
This mentorship formed the foundation of Zaslavsky's development as a violinist before he continued his studies at the Vienna Conservatory. Gorsky’s experience as a prominent violinist, composer, and pedagogue would have significantly influenced Zaslavsky’s technical and artistic formation, preparing him for his later successful international career.
