B Spanish — Charango
Here is B Spanish across the neck, home lit at every occurrence, ready to strum and hear.
B Spanish is 7 notes to the octave (world family), drawn here across the Charango's GCEAE courses with every B marked, so home stays visible from anywhere in the pattern.
Fiery and exotic — the b2 presses against the root while the major 3rd keeps it from sounding plainly minor. Flamenco heat with a Middle-Eastern edge: dramatic, urgent, and passionate.
Heard in: Flamenco and Spanish classical guitar, klezmer and "Hava Nagila", Arabic and Jewish liturgical music, metal riffs, and the V chord of harmonic minor.
Five courses tuned GCEAE spread a scale wide for a strumming instrument: two courses share the same pitch class an octave apart, so a run can cross the twin E and land on the same note it just left. These maps mark every root so a line never loses home mid-course.
Practise it as a shape the whole hand crosses, not a ladder one finger climbs: pick four of its notes, rake them as a two-bar phrase against a slow pulse, then slide the same phrase to the next position. That is how this instrument actually uses a scale — raw material for a strummed line.
