Architektonische Musiktheorie-Kathedralenplakate

A 2x2 grid of four luxury architectural music theory infographic posters, 16:9 aspect ratio, dedicated to famous composers: [Johann Sebastian Bach, Ludwig van Beethoven, Wolfgang Amadeus Mozart, Frédéric Chopin]. Each quadrant translates a composer's musical identity into a sacred architectural cathedral plan and acoustic diagram: chords rendered as gothic vaulted arches, rhythm as structural processions, and melodic lines as navigable spatial routes through rose windows and harmonic geometry. Surrounding each central cathedral layout are engraved orchestral score notations, staff lines, measure numbers, chord diagrams, waveform panels, and tonal harmonic maps. Typography includes a large composer title, period and key subtitle, and fine microtext notation annotations. Lighting features warm concert hall dusk glow, candlelit score paper tones, polished wood reflections, and embossed gold foil linework. Style is a high-end conservatory collector's edition print with fine architectural drafting. Constraints: clean geometric layout, no randomly floating music notes, no chaotic soundwave clutter.
