The Saint Petersburg school refers to interrelated circles of 19th-century Russian Western Classical composers centered in Saint Petersburg. Its core aim was to develop a distinctly Russian national style within Western art-music forms, blending European conservatory craft (symphony, opera, chamber music) with Russian-language declamation, folk-like melodic turns, Orthodox-tinged sonorities, and programmatic subjects drawn from Russian history and literature. In practice, the term often overlaps with the so‑called “Mighty Handful” (Balakirev’s circle) and their broader St. Petersburg milieu, where national-romantic aesthetics were pursued alongside vigorous debate with more academically oriented musicians.

An overture is an orchestral piece that traditionally serves as the opening to an opera, ballet, or stage work, and later evolved into an independent concert genre. Two foundational models emerged in the Baroque era: the French overture (slow, majestic dotted-rhythm opening followed by a faster, often fugal section) associated with Jean-Baptiste Lully, and the Italian overture (sinfonia) with a fast–slow–fast three-part design that presaged the Classical symphony. During the 19th century, the overture expanded into programmatic concert works, sometimes called "concert overtures," that used sonata-allegro or hybrid forms to depict narratives, scenes, or dramatic ideas. Overtures are characterized by bold thematic statements, clear formal signposts, and striking orchestration for full ensemble—strings, woodwinds, brass, and timpani—often designed to set the dramatic tone, preview motifs, or energize an audience before the curtain rises.

Classical music is the notated art-music tradition of Europe and its global descendants, characterized by durable forms, carefully codified harmony and counterpoint, and a literate score-based practice. The term “classical” can refer broadly to the entire Western art-music lineage from the Medieval era to today, not just the Classical period (c. 1750s–1820s). It privileges long-form structures (such as symphonies, sonatas, concertos, masses, and operas), functional or modal harmony, thematic development, and timbral nuance across ensembles ranging from solo instruments to full orchestras and choirs. Across centuries, the style evolved from chant and modal polyphony to tonal harmony, and later to post-tonal idioms, while maintaining a shared emphasis on written notation, performance practice, and craft.
