- How is old school different from boom bap?
- Consecutive eras, opposite methods. Old school runs fast at 100–115 BPM over whole funk breaks and functions as party music; boom bap drops to 85–95 BPM, chops those same breaks apart and reassembles them, and its snare is drier and harder. Prompt “fast funk break loop, party MC” for one and “slow chopped drums, dusty snare” for the other.
- What keeps a prompt from drifting into modern rap?
- Rule out the two modern signatures by name: “no 808 sub bass, no triplet hi-hat rolls.” Then add period gear cues — “early eighties, funk break loop, electric bass, turntable scratches, handclaps” — and the model stops reaching for contemporary trap production.
- How should the vocal be treated?
- Not dry and modern. Ask for “room reverb on the vocal, light compression, a little clipping allowed,” and keep the delivery mid-paced with simple end rhyme. The period character comes from a live PA and tape; a heavily tuned, close-mic'd vocal erases it.
