A chord progression where the dominant chord is the final chord of the cadence and is preceded by the tonic chord in second inversion (I 6/4-V). It should be noted that this pattern produces two chords with the same bass note in both chords. The " I" represents the chord based on the first step of the scale (with the 6/4 indicating) and the "V" represents the chord based on the fifth step of the scale. In the tonality of "C" major, a half cadence would be the tonic in second inversion (I 6/4) C major chord (GC E) moving to the dominant (V) G major chord (GB D). Also, Half Close Cadence; Imperfect Cadence.A cadence that ends on the dominant instead of the tonic. also called an imperfect cadence.
