In classical music theory, the English cadence is a contrapuntal pattern particular to the authentic or perfect cadence. It features a flattened seventh scale degree against the dominant chord,[1] which in the key of C would be B♭ and G–B♮–D.
Popular with English composers of the High Renaissance and Restoration periods in the sixteenth and seventeenth centuries, the English cadence is described as archaic[2] or old-fashioned[3] sounding. It was first given its name in the twentieth century.
The hallmark of this device is the dissonant augmented octave (compound augmented unison) produced by a false relation between the split seventh scale degree.
