Variable SCALE_DEGREESConst

Available scale degrees for pattern notes in Arabic maqam theory.

Scale degrees represent the intervallic relationship to the root note (tonic):

• Negative prefixes (e.g., "-I", "-II") indicate notes below the root
• "R" represents the root/tonic note
• Roman numerals without prefix (e.g., "I", "II") indicate notes above the root
• Positive prefixes (e.g., "+I", "+II") indicate notes in the next octave

This system allows for patterns that span multiple octaves and include both ascending and descending melodic movements.
