Arvo Pärt’s Symphony No. 3 (1971).
Pärt is a fascinating composer — Beethoven-esque in that he straddles two eras. His early works are decidedly serialist but after some political and creative problems, he went silent for six years. When he came back, he’d developed a new style, language even: tintinnabuli based on his study of chant and choral music.
Symphony No. 3 is a transitional work, completed just before the aforementioned silent period. You’ll hear a little bit of everything in the above first movement — even the octatonic “Russian” scale.
