Tips for Blending Scales with Chords in Songwriting

To create catchy melodies, treat scales as 'note pools' over chord progressions. Here's how:

1. Outline Chords: Start melodies on chord roots/3rds (e.g., E or G# over E major).
2. Scale Switching: Verse in minor pentatonic, chorus in major for contrast (like in Ed Sheeran's hits).
3. Passing Notes: Borrow from parallel scales (e.g., blues b5 over pentatonic).
4. Rhythm First: Short motifs repeated with scale variations stick in ears.
5. Record & Iterate: Loop chords, noodle scales, refine hooks.

Practice daily: Pick a progression like Am-F-C-G, cycle scales. For advanced harmony, explore Berklee College of Music resources. Experiment—these 7 scales cover 90% of hits!
