Chord & FretC7 — dominant seventh
Notes on C: 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 chord joins the major triad to the minor seventh (Bb, in C). The third and seventh form a tritone that tends to resolve — C7 pulls toward F.
The same chord on all four instruments
Where to use it: Dominant, blues and any point of strong resolution.
