Hiding behind the modest title "study" is a true masterwork by Finland's founding father of musical modernism. It is the final part of a trilogy written in the 1920's, to which the works Fantasia and Pan also belong. It suffered the same fate as Merikanto's String Sextet and Nonet: the composer tore pages out in fits of frustration and self-criticism. Paavo Heininen, an important Finnish modernist in his own right, has undone the damage and reconstructed his composition teacher's work for posterity.
