F Ionian on Guitar

Ionian is the plain major scale — the resolved, "everything is fine" sound that most Western music treats as home. The notes of F Ionian are F, G, A, Bb, C, D, E. Its characteristic note is E — the major 7th — the one note that gives this major-type scale its colour.

It is the sound of nursery rhymes, pop choruses, and triumphant film endings. Every other mode on this site is this same set of notes with a different note treated as home, which is why learning Ionian well makes the other six come almost for free.

Over the drone, listen for how the major 7th leans hungrily into the root — that pull is what "resolved" actually means.
