The Ionian Mode
Ionian is the mode you already know by another name: the major scale. It's the brightest of the commonly used modes, and the yardstick every other mode gets measured against.
What is the Ionian mode?
The Ionian mode is built on the 1st degree of a major scale — which means it is the major scale. There's no new formula to learn here: Ionian and major are two names for the same seven-note pattern. It earns its own name only because it takes its place in a family of seven related modes.
Scale degrees: 1, 2, 3, 4, 5, 6, 7 — nothing raised, nothing lowered. Every other mode is described relative to this plain, unaltered pattern.
Where you'll hear it
Ionian is the default sound of Western tonal music — most pop, rock, folk, and classical melodies written "in a major key" are drawing on the Ionian mode without anyone needing to name it. It's the mode that feels resolved and stable enough to be a satisfying place to end a phrase, which is exactly why the other six modes are usually described as variations away from it.
