How to use this key
Every key is the same machine with different letters. Three of these chords feel like home (Bbm, Db, Gb), two lean away (Cdim, Ebm), and two pull back toward home (Fm, Ab). 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 Bb minor, the whole chart moves at once: transpose it to any key and every chord re-spells itself correctly.
Bb minor shares its entire chord set with Db major, its relative major; the same seven chords, heard around a different home. Its nearest neighbors on the circle of fifths are F minor and Eb minor, one accidental away in either direction.
