Every site in the Warrior Network draws the same chord on the same day, from one shared seed. The instrument sites show you where to put your fingers on it. This one shows what happens to a single chord when three sections have to take it at once, which is a different question and has three answers.
THE ARMONÍA gets a grip and a number: the span, in semitones, between the lowest and highest note it actually sounds. That number is the whole difference between a strummed section voice and a guitar being played as a guitar — inside an octave the chord arrives as one percussive event, wider than that and it spreads into a stack with a bass note under it. The span is computed against the vihuela’s real re-entrant octaves rather than read off the diagram, because on that neck the diagram and the pitch order disagree.
THE BASS gets two facts and no more, because two facts is what the section uses: which note sits at the bottom of the grip — the one the rest of the ensemble hears as the chord — and whether its octave is inside the same hand position. When it is, the standard doubled bass note is a grip rather than a stretch. When it is not, the day’s chord gets stated single, and the page says so.
THE MELODY gets its free notes: which of the chord’s tones fall on an open violin string before anybody stops one. Some days that is two strings; some days it is none, and a section that wants the chord tone has to place it.
THE DATE IS COMPUTED IN YOUR BROWSER, not on the server, and that is deliberate rather than lazy. This document is cached at the edge for hours, so a “today” baked into the HTML would confidently tell a visitor arriving after midnight what yesterday’s chord was. The reading below renders from your own clock; everything above it is true on every day of the year.
