What mode corresponds to a major scale?

The Ionian mode is synonymous with the major scale. In Western music theory, the Ionian mode is formed by the same sequence of whole and half steps that define a major scale: whole, whole, half, whole, whole, whole, half. This sequence produces a bright and happy sound typically associated with major scales.

Each mode has its unique tonal qualities and step patterns, making them distinct from each other. For example, while the Dorian mode has a minor quality with a raised sixth, and the Phrygian mode has a minor quality with a flat second, the Mixolydian mode is major but features a lowered seventh, resulting in a different sound. The Ionian mode stands out as it captures the pure major scale interval arrangement, which is crucial for building melodies and harmonies typical in Western music.
