About the A sharp Vietnamese scale
A sharp Vietnamese is used for Vietnamese-flavored and folk melodies. Think of it as a dark five-note scale with a minor third and flat sixth.
Its notes are A♯, C♯, D♯, E♯, and F♯. The formula is 1½ W W H 4 semitones.
A♯ Vietnamese draws four black keys from the piano, A♯, C♯, D♯, and F♯.
