Einari Marvia (1915-1997) was a Finnish composer, music publisher and musicologist. He studied composition with Erkki Melartin, Leevi Madetoja and Selim Palmgren. His style is harmonically rich and original. The influence of Brahms is particularly apparent in the keyboard idiom, which is quite dense at times and very demanding for the left hand. The legacy of European late Romanticism is also present in the rapidly shifting harmonies. The sonority of the texture, meanwhile, owes something to the Russian piano school. Piano Sonata Op. 16 (1945) is published now for the first time - and directly as an Urtext edition. Pianist DMus Risto-Matti Marin has delved into the deep end of the manuscript world; as a result of the research, a notable piano work now gets an edition it deserves.
