In music, we find that certain patterns of chords,
what we call chord progressions, recur frequently particularly at cadences.
And we remind ourselves, of course, of the commonest cadence, Ic V I.
[MUSIC]
>> Which sometimes, is, enhanced by, a
dominant seventh, on the the second last chord.
So we hear this.
[MUSIC]
>> So a seventh, is added to the dominant chord, which serves to
pull the music strongly towards the tonic, so it's a very strong
progression and gives a pleasing finality to the cadence.
You find in lots of music, for example the well
known carol, Hark the Herald Angel sing goes like this
[MUSIC]
>> Or Happy Birthday To You.
It goes like this.
[MUSIC]
And that's possibly the commonest of the cords progressions and cadences.
Another cadential progression which we often find in,
involves a different cord in the third to last
position instead of the one C, we find two B and often with a seventh added chord.
Let's stick to G-Major.
There G Major.
[MUSIC]
Chord two.
[MUSIC]
The supertonic sounds like that.
We add a seventh to it.
[MUSIC]
And then we put that in first inversion.
So, we rearrange the notes in this order.
[MUSIC].
And that's our third to last chord.
[MUSIC]
I'll just play that one once again.
[MUSIC]
In addition to these and other
cadential progressions, are recurrent patterns of chords.
We find chord sequences.
