A# Spanish, Mapped for the Bass

A# Spanish runs 7 notes to the octave, laid across this seat's EADG fretboard with every A# marked. A blues phrase is short and keeps coming home to one pitch; the marked notes are where it comes home to.

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.

On the bass a scale supplies the notes between one chord and the next — the steps a line takes on its way to the change — far more often than it is played as a run.

Whatever scale you start from, the blues bends it: the third and the seventh get pushed flat, or somewhere between flat and natural, and that pull against the chord underneath is most of what the idiom sounds like.
