In an error detection exercise, you see a large leap in the bass line. What type of chord could be inserted to create smoother, stepwise motion?
An inverted seventh chord could be used to connect the chords, which would allow the bass to move more smoothly in a stepwise fashion.
What is a common function of seventh chords in inversion within a progression?
Seventh chords in inversion often connect chords in an extended progression, allowing the bass line to have a melodic, stepwise quality.
What are the two types of leading-tone seventh chords?
The two leading-tone seventh chords are the fully-diminished seventh (viio7) and the half-diminished seventh (viioø7).
You are writing a progression and want to extend the feeling of the tonic chord before moving on. What chord could you place between two tonic chords to achieve this?
A leading-tone seventh chord (viio7 or viioø7) can be placed between two tonic chords to prolong the tonic area with smooth, stepwise voice leading.
Besides its dominant function, what is another role a leading-tone seventh chord can play?
When placed between two tonic chords, a leading-tone seventh chord can serve to prolong the tonic area through stepwise voice leading.
What is meant by a bass line having a "melodic stepwise quality"?
This refers to a bass line that moves smoothly and conjunctly, often by step, which is a common result of using inverted seventh chords.
How do leading-tone seventh chords relate to the dominant chord?
Leading-tone seventh chords share a dominant function with the V and V7 chords and can often be used as a direct substitute for them.
What is the primary function of a leading-tone seventh chord (viio7 or viioø7)?
A leading-tone seventh chord can substitute for the V or V7 chord, fulfilling a dominant function within the harmonic progression.
When analyzing a score, you find a viioø7 chord. What are its two most likely harmonic functions in that context?
The viioø7 chord is likely either substituting for the dominant (V or V7) or prolonging the tonic by connecting two tonic chords.
Describe the typical voice leading associated with inverted seventh chords.
Voice leading into and out of inverted seventh chords is typically smooth, characterized by having no or minimal leaps between notes.
