Final Answer:
The Roman numeral analysis that matches the seventh chord below is V7/V.
Step-by-step explanation:
To determine the Roman numeral analysis for the seventh chord, we need to consider the context of the chord in relation to the key of the musical piece. The symbol V7/V indicates a dominant seventh chord built on the fifth degree (V) of a secondary key (indicated by the slash).
For example, if the primary key is C major, V7/V would be D7 (the dominant seventh chord in the key of G, the dominant key of C). This analysis is often used to show temporary departures or modulations to other keys within a piece.
Understanding Roman numeral analysis in music theory is essential for describing harmonic progressions and relationships between chords. The V7/V notation specifically indicates a dominant seventh chord built on the dominant of another key, providing insights into the harmonic structure and tonal movement within a musical composition.
