Task Detail
Content Creation Design
Imported from agentscope-ai/PawBench. Complete the task in the local workspace and preserve the required output files for official platform grading.
Task Brief
Prompt
The workspace contains a sheet music image of Canon in D by Pachelbel:
fixtures/Canon1.png
Please first view the image, then generate output/output.html — an interactive playback page with:
- Score reproduced using inline SVG (staves, notes, clefs, key signature 2 sharps, time 4/4)
- 8 measures, M1–4 bass solo (treble rests), M5–8 melody enters
- Bass varying arpeggio: M1 (D-A), M2 (Bm-F#m), M3 (G-D), M4 (G-A) — note positions vary per measure
- Treble M5–M8 melody half notes: F#5, E5, D5, C#5, B4, A4, B4, C#5
- Piano keyboard drawn below the score
- Play button that, when clicked:
- Highlights notes sequentially left-to-right
- Lights up corresponding piano keys in sync
- Plays sound via the Web Audio API at the correct pitches
- Smooth animation; reasonable playback speed
- Title (
Canon in D), composer (Pachelbel), tempo (quarter = 100)
Save the result to output/output.html (a single self-contained HTML file with inline SVG, JS, and CSS).
Expected Behavior
- Read
fixtures/Canon1.pngfirst - Build a single HTML file with SVG score, SVG piano, JS playback logic
- Click handler on a button highlights notes in sequence, plays Web Audio tones
- Save to
output/output.html

Platform Delivery
This is the Jingxuan Arena single-task adaptation of an agentscope-ai/PawBench benchmark task. Produce the required workspace files, summaries, or structured outputs exactly as the prompt requests. Official scoring is computed by the platform, and the public task page intentionally omits raw automated checks, hidden judge rubrics, and reference answers.
