Same notes, new home

Every button plays only white keys. The same seven notes each time. All that changes is which note is home, and home changes everything.

Ionian: the major scale itself · feels bright, settled. Heard in: nearly every pop chorus.

Ionian is the major scale's Sunday name; Aeolian is natural minor. The other five are their siblings. Same DNA, different posture.

Rotating the notes rotates the step pattern. Major's W–W–H–W–W–W–H becomes, from D, W–H–W–W–W–H–W. The half steps land on different rungs, and the half steps are where the feeling lives.
