B♭ Ionian Mode
The B♭ Ionian Mode has a Major quality due to its Major Third D. The Ionian Mode, like B♭ Ionian Mode, 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, C 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♭ Ionian Mode in this example. B♭ Ionian Mode is classified as a heptatonic scale as it has seven notes, B♭, C, D, E♭, F, G, A. The B♭ Ionian Mode is also known as a diatonic scale which conforms to specific rules. Due to its popularity the Ionian Mode later became known as the Major Scale. B♭ Ionian Mode is therefore identical to the B♭ Major Scale.
