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.
