Press to hear the scale played ascending.
A major mode with a raised fourth — the sharp eleventh floats above the major triad, giving it a bright, dreamlike lift.
The notes
Each degree links to its pitch page. Note names use sharp spelling throughout — every accidental is written as a sharp (C♯, not D♭), the same convention as the note pages.
