Be Still My Soul -This well-known hymn tune is based on the tone poem, “Finlandia”, by Jean Sibelius. The composer actually arranged a section of his own composition as a hymn. This version is in the key of C, playable on lever/pedal harp, with no accidentals. It begins with full chords stating the main hymn tune, followed by a variation with easily executable and dramatic arpeggios. Intermediate level.
