Data Export

DiArMaqAr provides comprehensive data export capabilities designed to support both academic research and practical music-making applications. Users can export complete datasets including tuning systems, ajnās, maqāmāt, and modulation analysis results in structured formats.

Export Formats

JSON

Structured, machine-readable format maintaining complete data relationships:

{
  "maqam": {
    "name": "Maqam Rast",
    "ascendingSequence": [...],
    "descendingSequence": [...],
    "ajnas": [...],
    "transpositions": [...],
    "modulations": [...]
  }
}

Use Cases:

• Programmatic access in other applications
• Data analysis and processing
• Integration with custom tools
• API development

CSV

Tabular format suitable for spreadsheet software and statistical analysis:

Columns typically include:

• Pitch class values
• Mathematical representations
• Note names
• Intervallic relationships
• Source attributions

Use Cases:

• Statistical analysis
• Spreadsheet manipulation
• Data visualization
• Quantitative research

Scala (.scl and .kbm)

Scala is a widely-used format for tuning system representation, compatible with many music software and hardware.

Scala Tuning Files (.scl)

• Contains tuning system definition with pitch ratios or cents
• Comprehensive metadata from database
• Proper formatting for Scala software
• Includes bibliographic attribution

Scala Keymap Files (.kbm)

• Maps tuning system pitch classes to MIDI keys
• Defines reference note and octave size
• Enables accurate playback in compatible software

Use Cases:

• Integration with synthesizers and samplers
• Contemporary composition practice
• Software instrument design
• Hardware synthesizer configuration

Export Options

For Maqāmāt:

• Include/exclude transpositions
• Include/exclude modulation analysis
• Include/exclude embedded ajnās
• Include/exclude suyūr
• Specify pitch data formats

For Tuning Systems:

• All pitch representations

Integration Examples

Python Analysis

import json
import pandas as pd

# Load exported JSON
with open('maqamat_export.json') as f:
    data = json.load(f)

# Convert to DataFrame for analysis
df = pd.DataFrame(data['maqamat'])
# Perform statistical analysis

Scala Software

1. Export tuning system to .scl format
2. Import into Scala software
3. Load into compatible synthesizer
4. Play with accurate tuning

DAW Integration

1. Export Scala files (.scl/.kbm)
2. Import into DAW (e.g., via MTS-ESP, Kontakt, etc.)
3. Create instruments with authentic tunings
4. Compose using historical frameworks

Best Practices
