Greetings!
Today's video focuses on the Analysis of a couple of chord progressions featuring inverted
dominant seventh chords.
The skill of musical Analysis requires practice, and will provide you, the student, important
tools to use in your own writing and research.
If you have not viewed the clip on V7 Inversions, you need watch that one first.
See link in the Description.
That said, […] One additional point deserves reemphasis:
Whenever two or more chords follow one after the other, they may be marked with successive
sets of figures, such as "3," "53," "2," and so forth, over the same sustaining
bass note.
Each of the chords shares a proportionate time value of the bass note. [mus]
Sustaining instrument samples may help us
appreciate the effect, more so than the percussive tone color of the piano.
Here we layer choir and large pipe organ samples, and play the identical chord progression we
just heard, though a little slower and dramatic. Listen! [mus]
On to the Analyses!
The Steps include 1) labeling the Key, below the staff.
2) Writing in the Figures – which mark the inversions – over the bass notes.
3) Adding the Roman Numerals – which mark the scale degrees of chord roots – under
the bass notes.
4) label the Cadence, and 5) Play or Sing the Example.
Now for the first Analysis Example.
Let's listen the music. [mus]
Incidentally, if you want to obtain a copy of a century-old music theory textbook
– the Public Domain, copyright-free source of the two examples today – see the description.
Now that that's out of the way […] The first thing you have to figure out, is
what is the key of the progression, according to the key signature.
Write the letter name of the key below the staff, next to the bass clef sign.
Second, write in the figures over the bass notes.
Figures indicate inversions of triads and seventh chords.
By the way: Do let us know of any errors in our figuring!
Third, add Roman Numerals under the bass notes.
Roman numerals tell us what is the root of each chord, by scale degree, and also show
whether a chord is a triad (usually, just a letter), or a chord of four tones – a
seventh chord.
Fourth, label the type of cadence, whether perfect or imperfect authentic, Plagal, and
so forth.
Fifth, Play through the progression on a piano-keyboard, several times.
Besides the keyboard, you may also assign voice parts to a small mixed chorus – soprano,
alto, tenor, and bass voices – to practice singing through the examples in a group situation. [mus]
Very Good!
Now for the second Analysis Example.
Let's first listen to the progression as it might sound played on a piano [mus]
[mus]
Label the key, below the bass staff, according to the key signature.
Next, write in the figures over the bass notes.
Figures indicate whether triads and seventh chords are in root position, or inverted.
Have we made any mistakes in our figuring so far?
Then, add Roman Numerals under the bass notes.
Roman numerals mark the scale degree of the root of each chord, and also tell us whether
a chord is a triad, or a chord of four tones – a seventh chord.
Be sure to label the type of cadence, whether PAC, IAC, Plagal, and so forth.
Finally, Play through the progression on a piano-keyboard, several times.
Besides the keyboard, you may again assign voice parts to a small mixed chorus – soprano,
alto, tenor, and bass voices – to practice singing through the examples. [mus]
There you have it!
Today we reemphasized the effect that is produced when more than one vertical harmony is attached
to a single bass note by means of figures. [mus]
[mus]
Then we went through the Steps for harmonic
and contrapuntal analysis of a couple of four-part chord progressions that combined triads and
dominant 7th chords in various inversions.
We trust you will transcribe the two progressions yourself, as pencil-to-paper writing practice.
An upcoming presentation will introduce techniques for connecting inverted Dominant-Seventh-to-Tonic-Triad
chords in the Minor keys, which you can imagine may present a few difficulties, but nothing
"major." :-) (!)
