Second inversion refers to a specific type of chord voicing, where the third of the chord is in the bass position, while the fifth and the root notes are positioned above it. The term can be used interchangeably with "6/4 chord", "five-three chord", or "tertian-harmonic chord". In music theory, the second inversion chord is often associated with a dominant function, as it creates a sense of tension that resolves back to the tonic. Some composers may opt to use alternative terms for the second inversion chord, depending on the context and style of the music. Other synonyms include "inverted triad", "flatted third", and "sharp fifth chord".
