Today’s Chord, and the Modes That Hold It
The whole network’s pick for today, asked the atlas’s question: which modes, in which of the seven families, contain every note of it.
The network’s shared chord for today, read the way this site reads any set of notes: every mode of the seven families, rooted on the chord’s own note, that holds all of it, one row per family.
How the reading works
Every Warrior site draws the same chord each day from one shared seed, and the instrument sites show where the fingers go. Here the pick is asked what the atlas asks of any set of notes: which modes hold it? The chord’s notes are written as degrees over its own root, folded into one octave, so a ninth reads as a 2 and a minor seventh as a b7. Every mode of every declared family is then rooted on that same note, and a mode holds the chord when each of those degrees is one of its seven. The answer comes back one row per family, with every mode that holds the chord linked to its own row on its family page.
When a family holds none of it
A plain major or minor triad is held somewhere in all seven families. A richer chord narrows the field: a major seventh chord, for one, fits no mode of the melodic minor family and no mode of the Neapolitan major, and on those days their rows say so rather than dropping out of the table. From any mode the table names, the neighbours page shows what one altered degree reaches.
Where the pick comes from
The pick is the network’s, not this site’s: one seed shared by every Warrior site, a hash of the calendar date over a curated pool of chords, so it turns over once a day and is the same for everyone. It is worked out in your browser from your own local date, and the text of this page describes the method rather than naming a chord, because a chord written into the page would still be showing after midnight. If it is still yesterday where you are, yesterday’s chord is the right one.
