Acoustic, electric and electronic
The acoustic–electronic axis is a separate control from genre, and stating where you sit on it prevents half of all palette surprises.
Three categories, not two
- Acoustic — sound made by a vibrating body and captured by a mic: nylon guitar, upright bass, cello, brushed kit. Carries room and human variance.
- Electric — an acoustic action amplified and shaped: electric guitar, Rhodes, Hammond organ, electric bass. Still played, but the amp is part of the instrument.
- Electronic — sound generated rather than played: synths, 808s, samplers, drum machines. No room unless you add one.
People collapse the middle category and then wonder why 'acoustic' returned a Rhodes or 'electronic' returned a guitar amp. Naming all three correctly is a small vocabulary fix with a large payoff.
Hybrids are the interesting territory
Most contemporary music lives in a mixture, and the mixture is worth stating as a ratio rather than a list. 'Mostly acoustic with a sub-bass underneath' tells you which category wins when they compete; 'acoustic guitar and sub bass' does not.
The same applies to drums. 'Live kit with programmed hi-hats' is a specific and very common modern sound that you will not get by naming either alone.
| Hybrid | Write it as | Sounds like |
|---|---|---|
| folktronica | acoustic guitar and voice over glitchy programmed percussion | organic, intimate, modern |
| modern country | live band with programmed 808 sub under the chorus | radio country |
| electro-acoustic score | string section plus granular synth textures | contemporary film score |
| lo-fi hip-hop | sampled Rhodes, programmed dusty kit, vinyl noise | warm, looping, study-friendly |
Say what should not appear
Negative cues are unusually effective on this axis because the categories are so distinct. no synths, no electric guitars, no drum machines, all acoustic instruments — each one closes off a large region of possible outputs for very few words.
Example
Practice
Take one arrangement and write it three times — fully acoustic, fully electronic, and a stated hybrid with a ratio — keeping genre, vocal and tempo identical. Generating all three gives you a direct read on how much of what you thought was 'genre' was really just sound-source category, which is usually more than expected.
