Erkki Melartin's Fantaisie EM 43 is a lesser-known late Romantic/Modern era work from the Finnish tradition. It features delicate melodic lines that transition between wistful lyricism and sudden harmonic shifts.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: a left hand with real melodic or rhythmic responsibility of its own; a true singing tone, with the melody floating above the accompaniment; and chord voicing — bringing out one note inside a handful of others.
Students must balance the thin, singing melody against a supportive accompaniment that requires sensitive voicing.
