What is the name of the cadence that ends with V or V7?

The cadence that ends with V or V7 is known as a Half Cadence. This type of cadence creates a sense of interruption or pause rather than a feeling of resolution. It typically occurs in the middle of a phrase or in a transitional section, leaving the listener expecting more, as it does not resolve to the tonic.

In a Half Cadence, the use of the dominant chord (V or V7) provides a strong pull towards the tonic, but since it does not resolve to the tonic (I), the musical tension remains. This is different from an Authentic Cadence, which involves a progression from V to I, providing a strong sense of closure.

While a Plagal Cadence also does not end on the tonic, it specifically moves from IV to I, which is different from the dominant-based function of a Half Cadence. A Deceptive Cadence, on the other hand, usually progresses from V to vi, surprising the listener by resolving to a chord other than the expected tonic.

Overall, a Half Cadence distinctly characterizes a moment where the music feels unfinished, making it essential for building musical phrases and creating anticipation in the composition.
