Modal RunsB 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 B Ionian are B, C#, D#, E, F#, G#, A#. Its characteristic note is A# — 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.
B Ionian across the whole neck
Over the drone, listen for how the major 7th leans hungrily into the root — that pull is what "resolved" actually means.
