Lydian scale has a bright, spacious sound thanks to its raised fourth, giving it a dreamy, floating quality that guitarists love for expressive solos and melodic lines. It’s great when you want something more open and uplifting than a regular major scale. Here you can choose the key you want and see the Lydian pattern on the fretboard, making it easier to understand its unique intervals and bring that airy Lydian vibe into your playing.
