How to use this key
Every key is the same machine with different letters. Three of these chords feel like home (A, C#m, F#m), two lean away (Bm, D), and two pull back toward home (E, G#dim). A progression is just a route through those three feelings, which is why the loops above work in any key: the numerals stay the same, only the spelling changes.
Write with the letters, think with the numerals. If a melody outgrows A major, the whole chart moves at once: transpose it to any key and every chord re-spells itself correctly.
A major shares its entire chord set with F# minor, its relative minor; the same seven chords, heard around a different home. Its nearest neighbors on the circle of fifths are E major and D major, one accidental away in either direction.
