How Music Developed A Critical and Explanatory Account of the Growth of Modern Music — Key Ideas to Explore

Church Counterpoint and the Secular Current

The early chapters emphasize that for centuries the only artistic music was ecclesiastical. Henderson describes the Ambrosian and Gregorian chants as unsystematic collections derived from local sources, and credits Nokter Balbulus with introducing sequences. The birth of counterpoint in the church is presented as a purely liturgical development, yet the author repeatedly notes that popular music continued alongside it, eventually forcing changes. The tension between the two is a recurring pattern: the church’s polyphonic style reached its golden age, but the simplification of music—a move toward clearer, more singable lines—came partly from secular influences. Henderson’s account of the piano’s evolution similarly contrasts the polyphonic style of earlier keyboard music with the monophonic style that enabled the sonata.

Mendelssohn and the Oratorio’s Divided Heritage

In the chapter on oratorio, Henderson uses Mendelssohn as a case study in stylistic negotiation. He notes that Mendelssohn rejected both Handel’s Italian manner and Bach’s austere polyphony, seeking instead a graceful, fluent melody suited to Protestant sentiment. The analysis is precise: Henderson points out that Bach’s recitatives, though dramatically direct, were weakened by the evangelist’s narration and by their overly detailed musical character. Mendelssohn’s solution—the chorale as an embodiment of Protestant faith—is presented as a synthesis, but Henderson also criticizes St. Paul for being episodic and lacking dramatic continuity. The discussion is grounded in specific compositional choices, not general praise.

Opera’s National Styles and Reform Impulses

Henderson devotes several chapters to opera, tracing Italian, French, and German traditions from the birth of the form through Gluck, Meyerbeer, and Wagner. The pattern of tension reappears: Italian opera emphasized melody and vocal display, while French opera incorporated spectacle and dance, and German opera sought dramatic unity. Gluck’s reforms are positioned as a reaction against excess, and Wagner’s music drama as the culmination of a long struggle between musical and dramatic priorities. Henderson’s treatment is critical rather than celebratory; he notes, for instance, that Meyerbeer’s influence was significant but does not inflate his reputation. The closing chapter, “The Lessons of Musical History,” explicitly draws these contrasts together, urging readers to see development as a series of choices between competing aesthetic forces.

Readers will benefit from attending to Henderson’s persistent framing of musical history as a set of oppositions—sacred versus secular, polyphonic versus homophonic, national versus universal. The book is less a chronicle of masterpieces than an argument about how stylistic tensions drive change. Because the excerpts are incomplete, the full arc of Henderson’s argument cannot be verified, but the pattern is consistent enough to guide a critical reading: watch for the moments when two traditions collide and a new form emerges.

I keep thinking about Henderson’s quiet tracing of how church song and street song borrowed from each other, and it reminded me of a gentler companion volume sitting beside it, like old sheet music found in a drawer. The art of music. Vol. 01 (of 14) — Reading Notes lingers the same way—less argument, more margin notes from someone who loved the listening itself. It stayed with me softly.
