Music theory infographic titled "Natural, Harmonic, and Melodic Minor Scales". Archetype: SCALE MODES. Editorial music education poster in a retro 1970s vinyl aesthetic, minimal monochrome palette, clean high-contrast print texture, subtle record-sleeve geometry, sophisticated vintage layout. Show a precise central comparative scale diagram for general theory: three aligned staff-based scale examples and interval formulas for Natural Minor, Harmonic Minor, and Melodic Minor. Use standard notation with treble clef and ascending/descending examples where musically required, especially Melodic Minor with different ascending and descending forms. Include clearly separated sections for semitone/whole-step patterns, scale degrees 1–7, and highlighted altered degrees: b3, b6, b7 for Natural Minor; raised 7 for Harmonic Minor; raised 6 and 7 ascending for Melodic Minor, reverting descending. Add small keyboard interval diagrams beneath each scale to reinforce step structure, with precise note placement and musically accurate intervals. Use canonical note names only where needed, and canonical Italian terms only if included. No copyrighted song lyrics or recognizable song sheet music.
