Home vs Address: One Scale, Two True Answers

Ask three teachers "what is the Man Gong scale?" and you may get three answers: a pentatonic mode, a Phrygian thing, a minor-pentatonic cousin. Here is the uncomfortable part: several answers can be true at once — and publishing two of them unlabeled is exactly how students end up believing modes are chaos.

Dead Sea Scales fixes it with one rule. Every scale gets exactly one Home and one Address. Never two Homes.

Home — where you start hearing it

The Home is the pedagogical answer, spoken first. It places the scale in the nearest territory you already know: major sounds live in Ionian territory, minor sounds live in Aeolian territory. Man Gong's Home: "Aeolian territory — the minor pentatonic's cousin." That is where your ear should stand when you first play it.

Address — what it structurally is

The Address is the identity recorded in the reference system: the exact position on the map. Man Gong's Address: the Phrygian position of the pentatonic. Both statements are true. They answer different questions — "where do I start?" versus "where does it live?"

The classic traps, solved

Scale	Home (say first)	Address (the record)
Man Gong	Aeolian territory — minor pentatonic's cousin	Pentatonic, Phrygian position
Melodic Minor	"Dorian with a raised 7th"	Blues family — the Ionian ♭3 system
D Aeolian	D minor — the natural-minor home base	6th mode of F Ionian — the 5 Missing Notes are read from F
Harmonic Minor	"Aeolian with a raised 7th"	Harmonic family, Aeolian position

Notice what the doctrine forbids: it never lets a Home overwrite an Address in the reference docs, and it never gives a student two Homes. One place to stand, one line in the record.

The tools speak it

Open the interactive tool or the Fretboard Decoder+ and watch the identity banner: Home first, Address second, on every scale, in every key — including the Ionian anchor the 5 Missing Notes are read from. The doctrine is not a lecture. It is built into the machine.
