What is a 4 3 chord?

Chords of the sixth that take the figures 6/4 or 6/4/3 (or an abbreviation such as 4/3) are second-inversion chords. They are so named because the fifth of the chord (the second member of the chord above the root) is in the lowest voice.

How do you resolve leading tones?

How does the 7th of the V7 chord resolve?





If the seventh is in the bass, it must resolve down by step, creating a first-inversion I chord. V7 to VI (or vi) will often double the 3rd in the VI (or vi) chord, just like triads (that is, V to VI or V to vi). When circle-of-fifths sequences occur with seventh chords, the sevenths resolve down by step as usual.

What is the 7th chord in a major scale?

A major chord vii



The A major chord viiø7 is the G# half-dim7 chord, and contains the notes G#, B, D, and F#. This subtonic 7th chords root / starting note is the 7th note (or scale degree) of the A major scale. The roman numeral for number 7 is ‘vii’, and is used to indicate this is the 7th chord in the scale.

Why is a 7th chord called dominant?

The reason behind its name “dominant seventh chord” is because, in a C7 chord, the B flat is the 7th note of the C dominant scale (also known as the Mixolydian scale). This contrast with the regular major 7th found on a Cmaj7 (which is the note B natural).



What does a 7th resolve to?

The dominant seventh chord resolves to a major or minor chord whose root is a perfect fifth below its root.

Why is the 7th chord diminished?

The diminished 7th chord is used in a similar way in minor keys, typically to create more tension over the 5 chord. In the key of A minor for example, E7 would be our dominant chord, based on the harmonic minor scale.

Why is leading tone important?

It is commonly used as a passing chord between a root position tonic triad and a first inversion tonic triad: that is, “In addition to its basic function of passing between I and I6, VII6 has another important function: it can form a neighboring chord to I or I6.” In that instance, the leading-tone triad prolongs tonic



What is the dominant key?

What is the difference between a leading tone and a subtonic?

The term subtonic is generic while leading note is specific. While subtonic can be used for every seventh tone (irrespective of its distance from the tonic), the term leading note is specifically used for the seventh tones that are a half-step below the tonic.

Is subtonic major or minor?

In natural minor, the seventh note is a whole step below the tonic. In this case, the note is called a subtonic. In natural minor, the seventh note is a whole step below the tonic. In this case, the note is called a subtonic (or “flattened leading note”).



What is a flattened 7th?

In music, the subtonic is the degree of a musical scale which is a whole step below the tonic note. In a major key, it is a lowered, or flattened, seventh scale degree (♭ ). It appears as the seventh scale degree in the natural minor and descending melodic minor scales but not in the major scale.
