B♯ Aeolian Mode

The B♯ Aeolian Mode has a minor quality due to its minor Third D♯. The Aeolian Mode, like B♯ Aeolian, is one of seven diatonic modes originally formed using just the natural notes (think just the white keys on a piano) but starting on a particular note, A in the case of the Ionian Mode, which creates a unique sequence of intervals. This mode can then be transposed to any key such as B♯ Aeolian Mode in this example. B♯ Aeolian Mode is classified as a heptatonic scale as it has seven notes, B♯, C, D♯, E♯, F, G♯, A♯. The B♯ Aeolian Mode is also known as a diatonic scale which conforms to specific rules. Due to its popularity the Aeolian Mode later became known as the Natural Minor Scale. B♯ Aeolian Mode is therefore identical to the B♯ Natural Minor Scale.
