Lecture 5.3 – Chord Names (Coursera – Fundamentals of Music Theory 34)


[BLANK_AUDIO] You’ve already heard some of the chord
names. That is what we call the triads, which are built up on different degrees of the
scale. Let’s take the scale of F-Major. [MUSIC] Where we’ve encountered the tonic, which
is chord one. A dominant, which is chord five. [MUSIC] And the sub-dominant, which is chord four. As we hear these are all major triads. [MUSIC] And they’re the three most common, in
fact, some music is harmonized entirely by these
three chords. [MUSIC] But as briefly mentioned before, the diatonic scale of course, contains seven
notes. [MUSIC]. Back to the beginning, and a triad can be
built on all of them. Not all the triads we find, will be major. But let’s go up, and investigate them. First of all, sticking to the key of F,
we’ve had the tonic, on the first degree of the
scale. And then above the tonic. [MUSIC]>>Chord two is called the supertonic,
because it’s one step above the tonic. And as you’ll hear, the triad is minor,
with the notes G, B-flat, and D. We have to remember that the triads have
to be made up of notes, which are part of the
scale. [MUSIC] So it has to be one of those notes. So in this supertonic we have the G,
B-flat, and D. Going up another step, the third degree of
the scale is called the mediant, what we call chord iii, and its
notes are A,C, and E. The sub-dominant we know. [MUSIC]. The dominant we know. [MUSIC]. And sub-mediant, chord six is another
minor triad. In this case consisting of D, F, and A. The sub-mediant you remember is what we
hear in the interrupted cadence that we talked
about. [MUSIC] And then finally, in the context of F we
have,. [MUSIC]. The final triad, which is built on seventh
degree of the scale. [MUSIC] And which is a diminished triad as you’ll
hear, the notes are E, G and B flat, and that’s
chord seven. So to go up through all of these in F-Major, here we go chord one, two, three, four, five, six, seven. [MUSIC]>>And back to one. Let’s just try them in another key, here’s
C-Major. One, two, three, four, five, six, seven [MUSIC] And back to one.
