E♯ Ionian Mode

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