Major 7th Flat 5 Chord

🎵 An unusual chord (root, 3, b5, 7) sometimes called Lydian b5. It has a bright but slightly unstable feel due to the flat fifth clashing with the major 7th and root. Use it for ethereal, perhaps a bit jarring, or floating soundscapes, often in film scores or experimental music.

Also abbreviated as: M7b5
