Question

Please help!! i'm stuck on this

Answer 1

The iiø7 to V (dominant) progression in a minor key is a classic example of how harmonic conventions guide and shape the tonal language in music.

In a minor key, when moving to the dominant chord, the most common and predominant seventh chord is the iiø7 (minor ii half-diminished seventh chord) in first inversion.

Let's break down the Roman numeral analysis you provided:

iiø7: This indicates the minor ii half-diminished seventh chord. In the context of a minor key, it's built on the second degree of the scale and consists of the root (minor second), minor third, diminished fifth, and minor seventh.

Inversion (ø6/5): The inversion is specified as Ø6/5, which means the chord is in its first inversion.

In this inversion, the third of the chord is in the bass, followed by the root and fifth.

Moving from iiø7 (in first inversion) to the dominant chord allows for a smooth and stepwise bass line, which is a characteristic feature in classical and traditional harmony.

The leading tone (seventh scale degree) is often approached by a half step from below, creating a strong sense of tension and resolution as it moves to the tonic in the dominant chord.

This harmonic progression is commonly used in various musical genres, contributing to a sense of forward motion and harmonic richness.

Answer 2

`\Large\text{$\sf {ii^(\Phi)}^6_5$}`

Step-by-step explanation:

In music theory, the term "predominant" refers to a category of chords that typically precede the dominant chord (V) in a harmonic progression. Adding a chordal seventh to predominant chords can intensify their motion to the dominant.

"ii" means the triad based on the second degree of the scale (supertonic).

"ø" represents a half-diminished seventh chord, which is composed of a root note, together with a minor third, a diminished fifth, and a minor seventh.

The numbers in the given chord notation represent the intervals above the bass note:

• 
  `{}^6_5` is a first inversion chord, which means the 3rd of the chord is the bass note.
• 
  `{}^4_3` is a 2nd inversion chord, which means the 5th of the chord is the bass note.
• 
  `{}^4_2` is a 3rd inversion chord, which means the 7th of the chord is the bass note.

The most common predominant seventh chord is the first inversion. This is because the bass note of a first inversion predominant seventh chord resolves upwards in a stepwise manner to the bass note of the dominant chord in root position.

For example, in the key of A minor, the supertonic half-diminished seventh chord (iiø) consists of the notes B, D, F, A. In its first inversion, the bass note is D. The dominant chord in the same key consists of the notes E, G# and B, where E is the bass note. So, using the first inversion of iiø allows the bass note D to resolve upwards in a stepwise manner to E.
