- How do I actually get shifting meters when generating?
- Name the time signatures: "verse in 7/8, chorus returning to 4/4, bridge in 5/4." Writing "odd meters" or "complex rhythm" usually still returns tidy 4/4. Specifying the signatures is what makes the style possible at all.
- How does progressive rock differ from psychedelic rock?
- Progressive pursues structural complexity and precision — the meter changes, suite forms and virtuoso passages are all designed. Psychedelia pursues blur and expansion with loose structure and atmosphere first. One makes you admire the architecture; the other makes you lose your bearings.
- Does it work as background music?
- Poorly. Its structural shifts and dynamic swings demand continuous attention, so it distracts rather than supports. When you need textured instrumental music that stays out of the way, post-rock or ambient are better fits.
