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 bowed instrument the answer has to be smaller than the chord.
A bow reaches two strings comfortably and four only as a broken gesture, so a fiddler does not really play chords: they play double stops, two adjacent strings at a time, and let the ear assemble the rest. That makes the daily question a different one — not "where is this chord" but "which pairs of it are actually playable, and where does the hand have to be to reach them".
The position is chosen by counting, not by preference: the page ranks every position by how many adjacent pairs sound two different chord tones, then by how many of those pairs ride an open string, then by how few fingers the whole thing costs. The winner is printed with the finger each note wants.
Open strings get their own reading, because they are the one note nobody has to place. An open string that belongs to today's chord can ring under the line for free and stay perfectly in tune while doing it; one that does not belong has to be stopped. The page names all four either way.
The chord 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, today's pairs appear below.
While you wait — or if scripting is off — the position pages map the hand across the whole fingerboard, and the scale pages carry the same open-string reading under a line instead of a chord.
