Rimsky-Korsakov was asked for advice and guidance not just on the Russian Symphony Concerts, but on other projects through which Belyayev aided Russian composers.
Rimskii-Korsakov recibiu unha petición de consello e asesoramento, non só sobre os Concertos Sinfónicos, senón noutros proxectos nos que Beliaev axudaba a compositores rusos.
