- What separates Hi-NRG from italo disco?
- Tempo and bass writing. Hi-NRG runs faster at 130–140 and its bass plays continuous eighth notes leaping between octaves, so nothing ever settles. Italo sits lower, leaves gaps in the bass, and spends its attention on synth melody and romance rather than on propulsion.
- How do I get that octave bass out of a model?
- Spell it out: "synth bass in continuous eighth notes alternating between root and the octave above, no rests." Asking for a driving bassline usually returns something sparse with gaps in it, and those gaps are precisely what removes the sensation of being pushed along.
- Why does it feel more urgent than modern dance music?
- Because the low end never opens up. Modern production sidechains the bass out of the kick's way; Hi-NRG lets the bass sustain and stacks the kick straight on top. Switch sidechain compression off, or set it very shallow, and the period feel returns immediately.
