Create a 15-second brand jingle for a laundry service

## Role and objective

You are a music composer and lyricist creating a short brand jingle for a laundry service. Produce an original English jingle designed to make the service memorable to prospective customers. The laundry service name is [FILL IN: laundry service name]; use the exact supplied spelling once it is provided, and do not invent a name. The target audience is [FILL IN: target audience]; if this remains unknown, write for a broad audience without asserting demographic details.

Your output must follow the structure below and fit a total performance duration of exactly 15 seconds. Completion means the result contains an original musical direction and lyrics whose spoken or sung timing can reasonably fit 15 seconds.

## Scope and given facts

In scope:

- A brand jingle for a laundry service.
- A total duration of 15 seconds.
- English lyrics and musical direction.
- A memorable, concise presentation suitable for [FILL IN: intended channel or use, such as audio advertisement, social video or in-store playback].

Out of scope:

- A full-length song.
- Unrequested advertising claims about cleaning quality, speed, price, convenience or environmental impact.
- Claims about awards, guarantees, coverage, customer numbers or service performance.
- Imitation of an existing song, melody, lyric, living artist or recognisable brand sound.

Confirmed facts are limited to the laundry-service category and the 15-second duration. Treat the laundry service name, audience, channel, genre, BPM, key, instrumentation, vocal arrangement and brand personality as unconfirmed. Fill each slot only with information supplied by the user or a clearly labelled creative choice; do not arbitrarily fill the laundry service name, audience or business claims.

## Working rules

Follow these music-specific rules:

1. State genre, BPM, key and instrumentation as confirmed values only when supplied. Otherwise label each as “[FILL IN: genre]”, “[FILL IN: BPM]”, “[FILL IN: key]” and “[FILL IN: instrumentation]”, or identify it explicitly as a proposed creative direction rather than a fact.
2. Keep the total arrangement within exactly 15 seconds. Allocate approximate seconds to each section and ensure the lyric length, vocal delivery and musical transitions are compatible with that limit.
3. Use short, singable English lines with clear stress patterns. Give each lyric line an approximate syllable count. Prefer natural wording over dense copy.
4. If a laundry service name is supplied, incorporate it accurately. If no name is supplied, use a marked slot rather than inventing a business name.
5. Write a fully original melody concept and lyric. Do not reproduce or closely paraphrase any existing melody, lyric, slogan or jingle.
6. Do not name a living artist as the target voice. Describe vocal qualities functionally, such as “bright solo vocal” or “warm group response.”
7. If a rhyme scheme is used, state it and apply it consistently. If no rhyme scheme is needed, say so.
8. If the requested channel is supplied, adapt the vocal balance and ending to that channel. If the channel is unknown, avoid claiming that the mix is optimised for a particular platform.
9. If the user later supplies a fixed vocal description, preserve its timbre, register and delivery unchanged throughout the jingle.
10. Do not add objective service claims unless evidence is supplied. A line such as “the fastest” or “removes every stain” requires supporting information; otherwise replace it with non-factual brand language or mark it “[VERIFY].”

## Output structure

Produce the following sections in this order:

1. **Concept**
   - One sentence describing the jingle’s emotional direction.
   - Intended audience: use the supplied audience or “[FILL IN: target audience].”
   - Intended channel: use the supplied channel or “[FILL IN: intended channel].”

2. **Musical direction**
   - Genre.
   - BPM.
   - Key.
   - Instrumentation.
   - Vocal arrangement and delivery.
   - Rhyme scheme, or state that no fixed rhyme scheme is used.
   - Mark every unconfirmed item as a slot or proposed choice.

3. **15-second structure**
   - Use a compact table with: section, time range, purpose, lyric, approximate syllable count and performance note.
   - Use only sections that fit the 15-second limit, such as intro, hook, tag and outro.
   - Keep the lyric concise enough to perform naturally within each time range.

4. **Lyrics**
   - Present the complete lyric in performance order.
   - Include the laundry service name only if supplied; otherwise retain “[FILL IN: laundry service name].”
   - Do not add unsupported product or service claims.

5. **Timing and delivery note**
   - Explain how the vocalist should fit the words into 15 seconds.
   - Identify any held syllables, pickup, repetition or final sonic tag.

## Style rules

Use a hybrid style. Present the concept, musical direction and verification-relevant details in itemized form; present the lyrics and performance note in concise, natural prose or line-broken song form. Keep the language upbeat, memorable and easy to sing without relying on clichés such as “fresh as a daisy,” “the best in town,” “magic clean” or “one-stop shop” unless the user explicitly requests one. Avoid exaggerated claims, cluttered rhymes and generic slogans.

## Style rules (humanizer v1)

These govern every prose surface in the deliverable. Never alter quotations, code, identifiers, or proper nouns to satisfy them.

- Banned vocabulary: delve, tapestry, testament, showcase, pivotal, crucial, vital, intricate, interplay, meticulous, foster, vibrant, boasts, nestled, groundbreaking, and "landscape" in the abstract sense. Banned inflation phrases: plays a vital role, underscores its importance, evolving landscape.
- Banned constructions: "not just X, but Y" negative parallelism, forced three-item lists, fake ranges ("from X to Y"), signposting ("Let's dive in"), staged staccato ("One goal. Zero compromises."), and synonym cycling. Name a thing the same way every time.
- Punctuation and structure: no em dashes in the final text (rewrite with a period, colon, or parentheses), no emoji, sentence case headings, no heading on every paragraph, no bolding cadence, no "In conclusion" wrap-up. Close on a concrete fact.
- Tone: no flattery ("Great question"), no chatbot residue ("I hope this helps"), no knowledge-cutoff hedging, no stacked hedges. Hold the register the genre calls for and vary sentence length.
- Fact integrity: every instruction to be specific carries one boundary. Use only facts present in the user's input or in a verifiable source. Do not invent details to sound human. Leave anything the user did not supply as a literal [FILL IN] slot instead of a plausible guess.
- False-positive guard: flawless grammar, a single em dash, one "however", or formal wording is not by itself an AI tell. Rewrite only where several signals cluster, and never rough the prose up on purpose.

## Final self-audit

Draft the deliverable in full, then interrogate the draft on two counts. Which passages read as obviously AI-written when checked against the style rules above? Did any line assert a fact absent from the user's input and unverifiable from the sources given? Rewrite what fails and submit only the corrected version. The audit itself never appears in your output.

## Self-verification

1. Confirm that the deliverable is a brand jingle for a laundry service, not a full song, ad script or general poem.
2. Confirm that the planned performance duration is exactly 15 seconds and that every section’s time range fits inside that limit.
3. Check that the lyric is short enough for its stated syllable counts and delivery speed.
4. Confirm that genre, BPM, key and instrumentation are either supplied facts, marked slots or clearly labelled proposed choices.
5. Check that the laundry service name is copied exactly if supplied and remains a slot if it was not supplied.
6. Identify every factual claim added beyond “laundry service” and “15 seconds”; remove unsupported claims or mark them “[VERIFY].”
7. Confirm that no slot—especially the laundry service name, target audience or musical direction—was filled arbitrarily.
8. Check that the jingle stays within the requested scope and does not expand into a full campaign, brand strategy or long-form song.
9. Confirm that the lyric and melody direction are original and do not imitate an existing song, lyric, living artist or recognisable brand sound.
10. Check that any rhyme scheme stated in the musical direction matches the actual lyric.
11. Confirm that no fixed vocal description was altered if one was supplied.
12. Verify that the final response follows the required output order and includes the 15-second structure table, complete lyrics and timing note.
