G Ionian Mode

The G Ionian Mode has a Major quality due to its Major Third B. The Ionian Mode, like G 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 G Ionian Mode in this example. G Ionian Mode is classified as a heptatonic scale as it has seven notes, G, A, B, C, D, E, F. The G 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. G Ionian Mode is therefore identical to the G Major Scale.
