Two traditions, two different ways of reorganizing expectation. Listen for the pattern, the pressure, and the voice that changes what a pattern can do.
Modernism did not have one sound. These two paths offer different listening tools for hearing structure, disruption, freedom, and voice — each organized around the same three listening threads you'll meet throughout the music units.
Two separate pages: Blues & Jazz and Modernist Concert Music are full, independent pages, each with its own header motif, page signature, section terminator, and accent color — so each tradition reads as its own complete experience rather than a tab within a shared shell. This hub page is a pure, co-equal threshold: neither path is default or larger than the other. Shared organizing principle: both dedicated pages group their studies under the same three listening threads used across the music units — Structure & Freedom, Texture & Voices, Consonance & Dissonance — using the identical thread glyphs from that system, recolored to each path's own accent. Motif sourcing: the Modernist Concert Music page reuses the site's real Modernism ornament system (header band, page signature, section terminator) in its established rust tone; Blues & Jazz uses a parallel but distinct set of call-and-response arc motifs in the same structural roles, tinted in a comparable-weight smoky indigo — cousins, not lookalikes. Reduced motion: loading spinners are suppressed under prefers-reduced-motion; guide diagrams redraw on play/pause/seek rather than looping decoratively.
