When did 4 part writing allow 2nd inversion chords

When can you use second inversion chords?

Like first inversion, second inversion may be used to smooth out a bass line. Look at this example – notice the movement of the bass line. By using a second inversion V chord, the bass line moves by step and becomes smooth. A second inversion triad used in this fashion is called a passing six-four chord.

Is a 6 4 chord a second inversion?

“6/4” would be a second inversion triad, such as bass C combined with A and F. And there are others that are used for 7th chords, too.

What is a 4 over 2 chord?

The third inversion chord is called the “4/2” because the “3” is a 4th above the “7” in the bass and the “1” is a 2nd above the “7”.

Why is second inversion called 6 4?

Second inversion triads (6-4 chords, or “six-four” chords) have the fifth of the chord as the lowest note (also called the bass, pronounced “base”). They do not always follow the standard progressions from Section 5.3. Instead, they depend on nearby chords for their harmonic function.

What is a 4 2 inversion music theory?

V4/2. This is a 3rd inversion chord, with the 7th in the bass. The interval of a 4th refers to the 3rd of the chord, and the interval of a 2nd refers to the root. If this were a G7 chord, it would be spelled F-G-B-D.

Why is second inversion unstable?


Quote from video:

How do you use second inversion?

A chord (triad, seventh chord, or any other chord) with the 5th scale degree in the bass and the root and third somewhere above is said to be in SECOND INVERSION. For a triad, this would mean the chord is spelled (from bottom to top) either 5 – 1 – 3 or 5 – 3 – 1.

How do you know if its first or second inversion?



A triad is in “ root position ” when the root is the lowest note, “ first inversion ” when the third of the chord is the lowest note, and “ second inversion ” when the fifth of the chord is the lowest note.

How do you know which inversion to use?

A more reliable approach is to start listening out for which note is at the top (or the bottom) of the chord. For example, if you can hear that the root of the chord is on top, you know it is the first inversion of the chord. If it is the third of the chord on top, it is the second inversion, and so on.
