Space, texture and dirt: writing the room into a Suno prompt

Space is a decision, not an afterthought

Most prompts describe instruments and leave the space to chance. The tool fills the gap with its default: a polite medium room on everything. That default is where much of the generic comes from. Space is a genre signal as strong as tempo, so write it in the Styles field with the same weight as the drums.

The ladder has four rungs. Dry and close puts the source at the front with no audible room: dry drums, close-mic, in your face. Room adds short reflections: tight room, small dusty room. Hall adds a long tail: hall reverb, long decay. Cavern lets the space swallow the source: cavernous, washed in reverb. Each step up the ladder moves the result away from the club and toward the cinematic.

Pick one rung and commit. A prompt that asks for dry punchy drums and huge hall reverb in the same line gives the tool two rooms and no instruction about which instrument sits in which.

Echo families: slapback, dub delay, washed

Echo is not one word. Slapback is a single short repeat with no feedback: slapback echo on vocals reads as old tape machines and lo-fi vocal chains. Dub delay is rhythmic and filtered, repeats that feed back and become part of the groove: dub delay on snare, deep echoes. Washed means the repeats blur into a wall: washed-out delay, endless tails.

In dub, echo is not decoration. It is the genre. Delay throws are arrangement decisions — which hit repeats, for how long, and what stays dry underneath. Our Abyss Dub prompts treat echo that way: they name the elements that echo and keep the sub dry, because a mix where everything repeats turns to mud.

Texture and degradation: tape, vinyl, hiss

Degradation vocabulary is specific. Each word points at a different artifact, and the tool responds to the difference.

Decide where the dirt lives. Tape over the master is one aesthetic; degradation printed into the source is another. Our Noir Tapes folder puts tape treatment on the whole mix, while Fossil Jungle asks for resampled, degraded breaks — the dirt is in the material, not on top of it.

• tape saturation rounds the top end and adds soft compression
• tape warble adds pitch instability and reads as worn cassette
• vinyl crackle puts surface noise on top and reads as sampled
• hiss is broadband noise, the cheapest way to say lo-fi
• bit-crushed is digital and harsh, early sampler territory
• worn, degraded are loose words the tool interprets freely, so pair them with a concrete medium

Width and mono

Width belongs to the same vocabulary. wide stereo pads reads modern and expensive. mono, narrow reads older, sampled, focused. Neither is better; they are different eras. A fully mono mix commits to the sampled aesthetic, and the tool generally follows.

The useful move is to split the stereo field: mono drums, wide pads keeps a vintage center with modern edges. Whatever you choose, keep the low end narrow. A wide sub is energy the track loses on any real system.

Match the space to the genre

Every genre carries a default room and the tool has learned it. Fighting that default is possible but costs precision; aligning with it makes short prompts work harder.

• Trap wants dry drums at the front, with the 808 acting as the room; reverb on the kick kills the pocket
• Noir boom bap wants a small dusty room and tape over the master
• Dub wants deep rhythmic echo over a huge dry sub
• Dark garage wants a tight club space, short reverb on the skips and a dry low end
• Jungle wants the room already printed on the break, not added afterwards

When to ask for clean, and the stacking mistake

The most common texture error is stacking: lo-fi, tape, vinyl, hiss, dusty, degraded, warm analog in one line. The tool averages the pile into an unspecific haze — you asked for seven kinds of dirt and got none in particular. Pick one medium and one artifact: tape saturation, faint hiss says more than seven adjectives.

The opposite request is also legitimate. If the tool keeps printing crackle on a genre you want clean, say so — clean, modern, no lo-fi treatment — and move the persistent offenders to the Exclude field. How to phrase those lists is covered in the negative prompts guide. Our folders keep the 30 prompts and the 10 exclusion lists in separate documents so the two directions never blur.
