Two ways into a rock song
One of these was written as a score, section by section, inside the lyrics box. The other is a single sentence of description. Both work; they just hand over different amounts of control.
The prompt that made it
“[Global settings - Tempo 100 BPM, Key / Scale F# minor, Time Signature 4/4] [Intro - short dirty guitar riff, isolated snare] [Drop - explosive punk guitar riff, full band] Dobra, no dobra, dwa, trzy… [Verse 1 - tight punk groove, choppy guitar riff] Dobra (dobra), będzie dobrze już …”
Stage directions in brackets before every part — tempo, key, time signature, then “short dirty guitar riff, isolated snare”, then an explosive full-band drop — with Polish lyrics and shouted ad-libs in parentheses. The directions are not sung; they steer the arrangement, and the result follows the plan at 3:14.
The prompt that made it
“Cinematic dark rock, deep raspy male bass-baritone, powerful live drums, electronic drums and percussion, huge deep kick, heavy toms, deep bass, emotional electric guitar, piano, cinematic strings, dramatic build”
The opposite approach: one sentence naming the sound (“cinematic dark rock, deep raspy male bass-baritone, live drums, heavy toms, emotional electric guitar, cinematic strings”), no lyrics supplied. It came back at 5:03 — proof that a described brief can still build.
If you have words, paste them and direct the sections. If you have a sound in your head, describe the band and let the words be written. What you should not do is give half a sentence and expect either.
What rock briefs leave out
From every request between 4 September and 4 October whose description, style or genre menu named rock:
| In the request | Share of rock requests | What happens without it |
|---|---|---|
| A tempo or pace word | about 1 in 3 | Without one, the pace is chosen for you |
| A described song rather than pasted lyrics | about 1 in 3 | Two in three bring their own words — more than most genres here |
| Made with the Instrumental switch on | about 1 in 30 | Riff-only tracks are rare here; the switch is what gets them |
| Made on the free plan | about 9 in 10 | Almost everyone is trying it, not subscribing for it |
The cheapest improvement is a single pace word. “Fast, four-on-the-floor punk” and “slow, heavy, dragging” are two different songs from the same description of a guitar.
Which rock you mean
Name the band you are hearing in your head — not by name, but by its parts.
| If you want | Write | Roughly |
|---|---|---|
| Stadium anthem | “anthemic rock, big clean-to-crunch guitars, gang vocals on the chorus” | 120–140 BPM |
| Punk | “fast punk, buzzsaw guitars, shouted vocal, no polish” | 170–200 BPM |
| Grunge / 90s alt | “grunge, loud-quiet-loud, detuned guitars, weary male voice” | 90–120 BPM |
| Classic 70s rock | “70s rock, warm analogue drums, bluesy guitar solo” | 100–130 BPM |
| Power ballad | “power ballad, clean verse, huge distorted chorus, guitar solo” | 70–85 BPM |
| Heavy / metal-leaning | “heavy riff rock, down-tuned guitars, double-kick, growled chorus” | 140–180 BPM |
Add one line about the guitar tone and one about the voice, and the rest of the arrangement follows: “a clean verse that opens into a wall of distortion on the chorus, raspy male voice that sounds like it has been shouting all night”.
Bringing your own lyrics, and directing them
Custom mode sings the words you paste, in the language you wrote them in. The tags above the box — [Verse], [Chorus], [Bridge] — mark the sections, and as the first example shows you can put your own directions in brackets on the same lines: a riff to open with, an isolated snare, a drop where the whole band comes in. Those brackets are read as direction, not sung as words.
Lyrics taken from an existing song are declined before anything is generated and the credit comes back, so write your own or describe the feeling of the one you like.
How long, and what comes next
Measured from the files of rock songs made between 4 September and 4 October: median 3:16, eight in ten between 1:25 and 6:07, and one in four past five minutes — almost all of those from long lyrics people brought. If you want the long version of a described song, extend a finished take rather than asking for one up front — extending continues the same song, including its guitar tone.
Both takes stay in your library. Either can be covered in another style (a punk song as a country ballad is a genuinely useful test of the lyric), turned into a video, or split into stems on a paid plan if you want to sing over the backing yourself.
Before you press Generate
- The guitar tone in three or four words: clean, crunchy, buzzsaw, down-tuned.
- A pace word or a BPM.
- The voice: raspy, clean, shouted, gang vocals on the chorus.
- One structural line — where the song gets loud.
- Instrumental switch on if you want a riff track with no singing.
