Task Brief

Prompt

The workspace contains a sheet music image of Canon in D by Johann Pachelbel:

fixtures/Canon1.png

Please first view the image, then generate output/output.html reproducing the score using inline SVG with the following requirements:

Include the title (Canon in D), composer (Johann Pachelbel), tempo (quarter = 100)
Draw two staves: treble clef on top, bass clef on bottom, joined by a brace
Display the correct key signature (D Major: 2 sharps — F#, C#) and time signature (4/4)
Reproduce 8 measures total, in two lines of 4 measures each:
- Measures 1–4 (line 1): treble has whole rests; bass plays eighth-note pairs (arpeggios)
  - M1 (D-A): D3,F#3 / A3,D4 / A2,C#3 / E3,A3
  - M2 (Bm-F#m): B2,D3 / F#3,B3 / F#2,A2 / C#3,F#3
  - M3 (G-D): G2,B2 / D3,G3 / D3,F#3 / A3,D4
  - M4 (G-A): G2,B2 / D3,G3 / A2,C#3 / E3,A3
- Measures 5–8 (line 2): bass repeats the same ostinato; treble enters with half notes (2 beats each)
  - M5: F#5 / E5
  - M6: D5 / C#5
  - M7: B4 / A4
  - M8: B4 / C#5
Include barlines, stems, beams, dynamic markings (p at M1, m / mf at M5, crescendo near M4)
The bass arpeggio pattern must vary per measure (different note heights) — not a flat repeated pattern

Save the result to output/output.html (a self-contained HTML file with inline SVG).

Expected Behavior

Read the reference image fixtures/Canon1.png
Analyze the staff structure and notes
Construct a single HTML file with inline SVG drawing all 8 measures
Treble staff in M1–4 should be empty (whole rests)
Treble melody in M5–8 should descend then rise: F#5→E5→D5→C#5→B4→A4→B4→C#5
Save to output/output.html

Grading Criteria

Reads the reference PNG (file_read)
Output HTML exists and contains inline SVG (output_file_exists, has_svg)
Title and composer text present (metadata_present)
Treble & bass clefs and 4/4 time, 2 sharps (key_time_clefs)
8 measures organized in 2 lines (measures_count)
Bass arpeggio note positions vary across measures (bass_varies)
Treble M5–8 melody pitch labels appear (melody_pitches)
Reasonable file size (>4KB) (substantial_output)

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.
