B Lydian
B · C♯ · D♯ · E♯ · F♯ · G♯ · A♯
A major scale with a raised fourth, B Lydian sounds brighter and more open than plain major — floating rather than settled. It's the go-to scale for wonder and vastness in film scoring, and a favourite of fusion and progressive rock players. The raised fourth is the whole character of the mode, so make sure your lines actually land on it.
