Guitar: C# Spanish Over the Changes
Where C# Spanish lies at this seat, and what a chorus takes out of it.
C# Spanish runs 7 notes to the octave, laid out here on EADGBE with every C# flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
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.
A guitar chorus is a single line with the comp dropped, so a scale here is what the picking hand walks through between the two or three phrases it actually meant to play.
Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
