in which the
fifth of the chord is the

In music theory, the bass note of a chord or sonority is the lowest note played or notated. If there are multiple voices it is the note played or notated in the lowest voice (the note furthest in the bass.)

, a second-inversion triad is a chord (as in I), while a second-inversion seventh chord is a chord.
Note that any voicing above the bass is allowed. A second inversion chord must have the fifth
chord factor in the bass, but it may have any arrangement of the root and third above that, including doubled notes, compound intervals, and omission (G-C-E, G-C-E-G', G-E-G-C'-E', etc.)
Examples
In the second inversion of a C-
major triad
In music theory, a major chord is a chord that has a root, a major third, and a perfect fifth. When a chord comprises only these three notes, it is called a major triad. For example, the major triad built on C, called a C major triad, has pitch ...

Cadential
Cadential second-inversion chords are typically used in the
authentic cadence
In Western musical theory, a cadence () is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards.Don Michael Randel (1999). ''The Harvard Concise Dict ...
I-V-I, or one of its variation, like I-V-I. In this form, the chord is sometimes referred to as a ''cadential '' chord. The chord preceding I is most often a chord that would introduce V as a weak to strong progression, for example, making -II-V into II-I-V or making IV-V into IV-I-V.
:
The cadential can be analyzed in two ways: the first labels it as a second-inversion chord, while the second treats it instead as part of a horizontal progression involving

above a stationary bass.
# In the first designation, the cadential chord features the progression: -V-I. Most older harmony textbooks use this label, and it can be traced back to the early 19th century.
# In the second designation, this chord is ''not'' considered an inversion of a tonic triad but as a dissonance resolving to a consonant dominant harmony. This is notated as -I, in which the is not the inversion of the V chord but a
double appoggiatura on the V that resolves down by step to (that is, -V). This function is very similar to the resolution of a 4–3
suspension. Several modern textbooks prefer this conception of the cadential , which can also be traced back to the early 19th century.

Passing
In a progression with a passing second-inversion chord, the bass passes between two tones a third apart (usually of the same

In music, a passing chord is a chord that connects, or passes between, the notes of two diatonic chords. "Any chord that moves between one diatonic chord and another one nearby may be loosely termed a passing chord. A diatonic passing chord m ...
V is placed between them – though some prefer VII to V – creating

– – ). It can also be used in the reverse direction: I-V-I. The important point is that the V chord functions as a passing chord between the two more stable chords. It occurs on the weaker beat between these two chords.
The upper
voices usually move in step (or remain stationary) in this progression.
:
Auxiliary (or pedal)
In a progression with an auxiliary (or pedal) second-inversion chord, the IV chord functions as the harmonization of a
neighbor note in the progression, I-IV-I. In this progression, the third and fifth rise a step each and then fall back, creating a harmonization for the scale degrees – – in the top voice.
:
Bass arpeggiation
In this progression, the bass
arpeggiates the root, third, and fifth of the chord. This is just a florid movement but since the fifth is present in the bass, it is referred to as a bass arpeggiation flavour of the second inversion.
