It is a work of Johannes Brahms in 1864. Geistliches Lied, translated as Spiritual Song in English, is a work of mixed chorus and organ accompaniment with Brahms-like polyphonic harmonies and beautiful melodies in religious poems by Fleming. Lento & Vivace has arranged this piece into an instrumental solo with piano accompaniment. I recommend that you feel like you are playing in a peaceful and tense and resonant harmony that blends in.
