One chord a day, drawn by the whole Warrior Network from a single shared seed: a hash of the calendar date over a curated pool, so every sister site is looking at exactly the chord you are. What changes from site to site is the answer, and on a keyboard the answer is arithmetic about voices.
Why a keyboard has a different question
A guitarist asks where a chord tone lives, because on a fretted instrument some of them are genuinely out of reach. A keyboard player never asks that: every tone in every octave is under the hand, laid out in one repeating pattern. The question that actually bites here is how many of those tones the instrument will sound at once — and that is decided by the machine, not the player.
A piano and a drawbar organ hold everything you can physically press. An eight-voice polysynth holds everything two hands are likely to ask for. A four-voice starts making choices the moment a ninth chord shows up. A paraphonic synth sounds four keys through one shared envelope, so the chord breathes as a single object rather than four. And a mono synth cannot play a chord at all: it has to roll it.
The reduction, and its order
So the daily pick is voiced once from its interval formula — a plain root-position stack, no inversion, no cleverness — and then reduced once per keyboard on this site, through the same engine every chord page here uses. The drop order is fixed and honest: doublings go first (the highest instance, so the lowest survives), then an unaltered fifth, then the root, on the grounds that a bass player or a left hand usually has it covered. A tone the chord's name requires is never dropped; when the budget is smaller than the name itself, the reducer keeps the most name-defining tones and says out loud that the result is incomplete.
That last case is the interesting one, and it is why this page exists rather than showing one diagram. The same chord is a different object on each of these instruments, and the difference is not taste — it is a number in a registry.
Today’s pick appears below
The chord itself is computed in your browser, from your own calendar date, and never on the server: rendered pages here are cached at the edge for hours at a time, so a date baked into the HTML would cheerfully hand you yesterday's chord a minute after midnight. Once the page knows what day it is where you are, every keyboard on this site appears below with today's chord drawn on it and its reduction spelled out.
While you wait for it — or if scripting is off — the full library is browsable by hand: every chord, voiced and reduced, and the architectures themselves are explained in mono, paraphonic, polyphonic.
