His initial works had a mystical element, but he downplayed this to better fit socialist realism.
He attended the Moscow Conservatory (which he left in 1915), where he was a pupil of Nikolai Zhilyayev, Sergei Taneyev and Sergei Vasilenko (theory), Alexander Ilyinsky (composition) and Konstantin Igumnov (pianoforte).
His early music revealed the influence of Nikolai Medtner and Alexander Scriabin.
Alexandrov was also a strong proponent of Stanchinsky and edited much of his compositions for publication.
