🎵 A characteristic sound of the Lydian mode (root, 3, 5, 7, 9, #11). It's bright, spacious, and slightly magical or dreamy due to the raised 4th (sharp 11th) avoiding the perfect 4th clash with the 3rd. Use it as a tonic (I) or subdominant (IV) chord in jazz, fusion, or film scores for an open, sophisticated, and uplifting sound.
