Vyacheslav was born in 1982 in Yuzhno-Sakhalinsk, Russia. Vyacheslav’s musical talent appeared in his early childhood and soon it manifested so evidentely that his parents, not being musicians, ventured on a heroic step – they gave up everything in their hometown and moved to distant Moscow, having neither anything nor anyone in it – just in the purpose of professional music training of their son.
In 1991 being 9 years old Vyacheslav entered the Central Music School under the Moscow State Conservatory (class of Professor Manana Kandelaki), which he graduated from with honors in 2001. In 2001-1006 he studied at the Moscow Conservatory in the class of Professor Yuri Slesarev and graduated from it also with honors. In 2006-2009 he attended the Moscow Conservatory as a post-graduate student, and since 2008 he joined a teaching faculty of the Conservatory where he has a position of assistant professor at the Piano Department. From the 2008/2009 concert season V. Gryaznov has belonged to the Moscow Philharmonic Society which represents him in Russia. Since 2012 he has worked as a visiting professor of piano at Kurashiki Sakuyo University of Science and Arts (Japan).
