Task: Convert the user's input into a COMPLETE song structure and a music generation prompt.
|
| 79 |
+
|
| 80 |
+
1. **Music Prompt (English):** Describe the mood, instruments, BPM, and style suitable for an AI music generator.
|
| 81 |
|
| 82 |
+
2. **Lyrics (Match User's Language):**
|
| 83 |
+
- **Language Detection:** Detect the language of the "User Input".
|
| 84 |
+
- **Write the lyrics entirely in that detected language.**
|
| 85 |
+
- The song MUST be long enough for **3 to 5 minutes**.
|
| 86 |
+
- If the language is Persian/Arabic, do **NOT** use diacritics (اعراب نگذار).
|
| 87 |
+
- You MUST use the following structure tags exactly:
|
| 88 |
+
[Verse 1]
|
| 89 |
+
[Pre-Chorus]
|
| 90 |
+
[Chorus]
|
| 91 |
+
[Verse 2]
|
| 92 |
+
[Chorus]
|
| 93 |
+
[Bridge]
|
| 94 |
+
[Guitar Solo]
|
| 95 |
+
[Chorus]
|
| 96 |
+
[Outro]
|
| 97 |
|
| 98 |
+
**CRITICAL RULES FOR LYRICS content:**
|
| 99 |
+
- The "lyrics" field must contain **ONLY the words to be sung**.
|
| 100 |
+
- **ABSOLUTELY NO** descriptive text inside the lyrics.
|
| 101 |
+
- For instrumental sections, leave the content empty.
