The instruments below make a bluegrass band, and each one is there to do a job the others are not doing at that moment. That division of labour is what the band page is about. This page is the other half of it: the reference material for actually playing each chair — every chord, every scale, every key read as the number a caller would shout, and a map of the whole neck.
None of these is ours. Every one of them has a deep home elsewhere in the Warrior Network — the site that covers its whole family, its alternate tunings, its technique and its gear — and every page below carries the door there. What you get here instead is the bluegrass reading: the same chord, framed by the key that got called and the seat you are sitting in.
The dobro, and why some of its chords draw nothing
The bluegrass dobro is a squareneck resonator played face-up in open G with a steel bar, and that is exactly the instrument charted here: every chord is a straight bar across one fret or a short slant of it, never a fretted grip. Open G can only sound what its strings become under the bar, so a quality the tuning cannot spell that way keeps its page — the page says so plainly and draws nothing — and its root's chord list marks it. In a circle that is ordinary work: the dobro plays the part of the chord a bar can reach, or a single-string line through it, and leaves the rest to the guitar and the mandolin. The resonator family's deep home — its tunings, its technique, the whole of its chord library — is Guitar Warrior, and every dobro page here doors to the same page there.
