LLM-MusicTheory

A production-ready toolkit for designing and testing music theory prompts for large language models (LLMs). Features a modular architecture for composing reusable prompt components.

August 2025 migration: primary dataset now fux-counterpoint with unified --file/--files identifiers (stems of encoded filenames). Legacy --question/--questions flags still accepted (hidden) for backward compatibility; treat them as aliases of --file/--files.

Quick environment bootstrap:

# Install Poetry (if not already)
curl -sSL https://install.python-poetry.org | python3 -
export PATH="$HOME/.local/bin:$PATH"
# Use in-project virtualenvs
poetry config virtualenvs.in-project true
# Install base dependencies
poetry install
# (Optionally) add providers: poetry install --with google --with anthropic
# Run tests
poetry run pytest -q

Python compatibility: tested on CPython 3.11–3.13 (any ^3.11 per pyproject).

  --model claude \
    --file Q1a \
  --datatype musicxml \
  --context \
  --temperature 0.7 \
  --max-tokens 1000 \
  --save

Batch Processing

Run multiple prompts automatically for experiments:

# Test multiple models on same prompt (provider names)
poetry run run-batch --models chatgpt,claude,gemini --questions Q1b --datatypes mei

# Or use specific model names with auto-detection
poetry run run-batch --models gpt-4o,claude-3-sonnet,gemini-1.5-pro --questions Q1b --datatypes mei

# Full experiment across all combinations
poetry run run-batch \
  --models chatgpt,claude \
  --questions Q1a,Q1b,Q2a \
  --datatypes mei,musicxml \
  --context \
  --temperature 0.0

Available Options

Option	Required	Description	Example Values

Python API

For programmatic usage and custom experiments:

from llm_music_theory.core.runner import PromptRunner
from llm_music_theory.core.dispatcher import get_llm

# Initialize LLM
llm = get_llm("chatgpt")

# Create and run prompt
runner = PromptRunner(
    model=llm,
    question_number="Q1b",
    datatype="mei", 
    context=True,
    temperature=0.0,
    save=True
)

response = runner.run()
print(f"LLM Response: {response}")

Advanced Python Usage

from llm_music_theory.prompts.prompt_builder import PromptBuilder
from llm_music_theory.models.base import PromptInput

# Custom prompt building
builder = PromptBuilder()
prompt_input = builder.build_prompt_input(
    question_number="Q1a",
    datatype="musicxml",
    context=True,
    temperature=0.5
)

# Direct LLM querying
llm = get_llm("claude")
response = llm.query(prompt_input)

🧪 Testing

Settings and Configuration

Settings and configurations can be changed in src/llm_music_theory/config/settings.py. Currently, the only settings that you can change are the models. Each has a different price, performance, and niche. You can find information about the models, pricing, and their string identifiers here:

• OpenAI ChatGPT:
• Anthropic Claude:
• Google Gemini:

Run a Single Prompt

You can run a single music theory prompt against any supported LLM using the run_single.py script. This script combines your modular prompt components, sends the query to the selected API, and prints the model’s response.

Example command (new syntax):

poetry run run-single --model gemini --file Q1b --datatype mei --context --dataset fux-counterpoint

Legacy still accepted (alias): --question Q1b.

Common Flags (updated)

• --model (required): LLM provider: chatgpt, claude, gemini
• --file (required): File ID (stem of encoded file, e.g. Q1b)
• --datatype (required): Encoding format: mei, musicxml, abc, humdrum
• --context: Include contextual guides
• --dataset: Dataset folder inside --data-dir (default: fux-counterpoint)
• --temperature: Sampling temperature (default: 0.0)
• --max-tokens: Optional max tokens
• --save: Persist response under outputs
• --data-dir: Root data directory (default: ./data)
• --outputs-dir: Output root (default: ./outputs)

Legacy aliases: --question maps to --file (hidden), --examdate retained for old RCM layout but ignored for new dataset.

Listing Available Resources

You can list available files (new) plus legacy questions, datatypes, or guides:

• --list-files (preferred)
• --list-questions (legacy alias → same as list-files)
• --list-datatypes
• --list-guides

Example:

poetry run run-single --list-files --dataset fux-counterpoint

🏗️ Architecture

Dataset Layout (new)

data/
    fux-counterpoint/
        encoded/
            mei/        # MEI files (Q1b.mei, ...)
            musicxml/
            abc/
            humdrum/
        prompts/
            base/       # base_<datatype>.txt templates
            prompt.md   # unified question text (replaces per-question files)
        guides/       # optional contextual guide .txt/.md files

Legacy RCM layout (now renamed RCM6, still minimally supported for tests) used: data/RCM6/encoded/<ExamDate>/<datatype>/<Q>.mei and per-question prompt files under prompts/questions/<context|no_context>/<datatype>/Qx.txt.

Design Principles

• 🧩 Modular Architecture: Each component has a single responsibility
• 🔌 Provider Abstraction: Easy to add new LLM providers
• 🧪 Testable Design: Comprehensive mocking for cost-free testing
• 📦 Clean Packaging: Standard Python project structure
• ⚙️ Configuration-Driven: Environment-based settings management

Data Flow

1. Input: User specifies model, question, datatype, and context
2. Discovery: System locates required files using path utilities
3. Composition: Prompt builder assembles modular components
4. Dispatch: Core dispatcher selects and initializes LLM provider
5. Execution: Runner sends prompt and handles response
6. Output: Response returned to user, optionally saved to file

🧪 Testing

Comprehensive test suite with 84% coverage and zero API costs during testing.

📚 API Documentation

Core Classes

PromptRunner

Main class for executing prompts across LLM providers.

class PromptRunner:
    def __init__(self, model, question_number, datatype, context, **kwargs):
        """Initialize prompt runner with configuration."""
        
    def run(self) -> str:
        """Execute prompt and return LLM response."""

LLMInterface

Abstract base class for all LLM providers.

class LLMInterface(ABC):
    @abstractmethod
    def query(self, input: PromptInput) -> str:
        """Send prompt to LLM and return response."""

PromptBuilder

Modular prompt composition system.

class PromptBuilder:
    def build_prompt_input(self, question_number, datatype, context, **kwargs) -> PromptInput:
        """Build complete prompt from modular components."""

CLI Commands

• run-single: Execute single prompt
• run-batch: Execute multiple prompts in batch

For complete API documentation, see docs/ directory.

🔧 Troubleshooting

Common Issues

1. Import Error: No module named 'llm_music_theory'

# Solution: Ensure Poetry virtual environment is active
poetry shell
poetry install

2. API Key Not Found

# Solution: Check your .env file
cat .env
# Ensure no extra spaces around = sign
OPENAI_API_KEY=your-key-here

3. FileNotFoundError for data files

# Solution: Check data directory structure
ls -la data/RCM6/
# Should contain: encoded/, prompts/, guides/, questions/

4. Tests failing with "system prompt not found"

# This is expected - comprehensive tests are skipped when legacy data is incomplete
# Core functionality tests should pass:
poetry run pytest tests/test_models.py tests/test_runner.py -v
