Prompt

Act as a lyricist and vocal arranger who specializes in prosody (how syllables and word stress sit on a melody).

Material:
- Original lyrics or the melody’s syllable pattern (one line per row): {{original_lyrics}}
- Topic of the new lyrics: {{new_topic}}
- Language of the new lyrics: {{language}}
- Rhyme scheme: {{rhyme}}

Deliverables:
1. Analysis of the original: for each line, the syllable count and where the stressed syllables fall (mark them in CAPITALS). Note any elisions you are counting.
2. New lyrics about {{new_topic}}, line by line, with the same syllable count and stresses in the same positions.
3. Comparison table: line | original syllables | new syllables | stresses match?
4. Warnings: lines where you had to squeeze two syllables into one note, stretch a vowel over several notes (melisma), or where a word’s natural stress fights the beat.
5. Two alternatives for the hardest lines.

Constraints:
- If the pattern is ambiguous (I have not shown where the strong beats fall), ask me or ask me to mark the long syllables before writing.
- Do not reproduce the full lyrics of copyrighted songs; work only with what I paste or with the syllable pattern.
- Keep the language natural: change an idea rather than pad a line with filler words.

Format: numbered sections, the new lyrics in a separate block and the table at the end.

How to use it

  1. Paste the original lyrics or, if the melody is yours and has no words yet, a pattern like “da-DUM-da-da-DUM” per line.
  2. Enter the topic and the rhyme scheme you want.
  3. Sing the new lyrics over the melody and come back with any lines that do not fit.
  4. If you plan to publish new lyrics over someone else’s song, check which permissions you need first.

Usage example

Pattern: “da-DUM-da-da-DUM-da / da-da-DUM-da-da-DUM” · Topic: a coworker’s retirement send-off · Language: English · Rhyme: ABAB.

Sample output

4. Warnings

  • Line 2: "for a" is two quick unstressed syllables; at a fast tempo they can blur, so keep them light.
  • Lines 1 and 3: "morning / warning" put the unstressed "-ing" on the last note, which matches the soft ending.

5. Alternatives for the hardest lines

  • Line 2: "for the WORK that you've DONE" (same stresses, more direct)
  • Line 4: "now go HAVE some FUN" (5 syllables, stresses on 3 and 5)…

Frequently asked questions

Why do stresses matter as much as syllable counts?

If an unstressed syllable lands on a strong beat, the word sounds wrong when sung (“guiTAR” versus “GUItar”). Matching the count alone does not make a lyric flow.

Can I use this for a parody of a well-known song?

You can work on the pattern, but publishing new lyrics over a copyrighted melody may require permission from the rights holder, depending on where you live. For private or classroom use the risk is lower; check before publishing.
