Chord & FretC7(#5) — dominant seventh sharp five
Notes in C7(#5): C – E – G# – BbFormula: 1 – 3 – #5 – b7In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
The dominant with its fifth raised a semitone. The alteration tightens the tension and pushes the resolution — an extra step just before the arrival chord.
The same chord on all four instruments
Where to use it: A dominant heading to a minor chord, in jazz, choro and MPB turnarounds.
