I Love Coffee, I Love Tea and ‘Knuckles’ Intro to Circle of Fifths [Part IV]

This blog post shows how the duet chords in I Love Coffee, I Love Tea can help you understand the Circle of Fifths and learn about the most powerful chord progression possible in music: II-V-I.

This is Part IV of the I Love Coffee, I Love Tea blog series. Before you try this at home, make sure you’ve covered this step:

If you can check YES, now it’s time to focus on how the lower duet of I Love Coffee, I Love Tea and ‘Knuckles’ can introduce you to the Circle of Fifths and teach you the II-V-I chord progression.

Most western music is built with chords. Simply put, chords are three stacked tones that sound good together. In their most basic form, chords look like this:

On the piano:

G chord on piano.

In written music:

G chord on the staff.

Chord Progressions

In music, a chord progression is a series of chords that sound good in succession, one after the other.

The strongest chord progression is from chord V to chord I. That’s chord “five” to chord “one.”

Before we cover the II – V – I chord progression, let’s review a little about chords, how chords are named, and how they work in a key.

We’ll cover everything in the key of C to start, just to keep it simple.

Then we’ll transfer what we know about chords and chord progressions to G-flat, because that’s the key that I Love Coffee, I Love Tea is in.

This tutorial video teaches the II – V – I chord progression and the Circle of Fifths through I Love Coffee, I Love Tea:

How to name chords built on scale notes

In any key, a chord can be built on each and every note. Here is the C scale, made of the notes of the key of C.

You can build a chord on each note, or scale degree.

The chord built on the first note is called ‘chord one’ (identified with a Roman numeral I). This continues up the scale, with each chord taking its name and number from the scale degree on which it is built.

Action: Play the chords up the C scale, saying the chord names aloud.

G-flat Major

I Love Coffee, I Love Tea is in the key of G-flat major.

G-flat major scale.

The key of G-flat has six flats but don’t let that worry you.

Here’s a really simple way of remembering the pattern of black and white keys for the key of G-flat: it’s made of five black keys and two white keys (C-flat is a white key — how cool is that?).

The real G-flat scale would begin on the G-flat black key, but this is a simplified overview of the key pattern.

Notice that G-flat Major uses:

  • All five black keys.
  • The two white keys on either side of the set of three black keys.
  • The set of two black keys. These are on their own, with none of the surrounding white keys in use.

Let’s play chords in the Key of G-flat

Here are the chords built on the notes of the G-flat major scale. Play them, keeping in mind the above pattern of black and white.

If you mess up, don’t worry! Sometimes things get messy before they get better.

Action: Play the chords up the G-flat scale, saying the chord names aloud.

In the first example, you have the ii – V – I chord progression.

In the second example, chord II is major because of the C-natural. This is the II – V – I progression.

The Chords in I Love Coffee, I Love Tea

Here are the chords written in Roman numerals:

Chord one, chord two*, chord five, chord one. *Chord two is normally minor in a Major key, but in this duet, chord two is major, the true “five of five”, the strongest way to lead to chord five.

Major and minor chords

When you build chords on scale degrees, notice that chords I, IV and V (upper case Roman numerals) have a bright, happy sound — these chords are major.

Chords ii, iii, vi (lower case Roman numerals) have a sad or creepy sound — these chords are minor.

Chords I and V are major, and chord ii is minor. These are the basis of the featured chord progression from I Love Coffee, I Love Tea.

But wait! In the intro to this blog post, the chord progression was written II – V – I. The ‘two’ chord was the upper case II, not the lower case ii.

Major and minor chords are characterized by the middle note — if it’s a major 3rd above the lowest note of the chord, the chord is major. If it’s a minor third above the lowest note, the chord is minor.

You can turn any major chord into minor by lowering the middle note by a half step (semitone).

You can also turn any minor chord into major by raising the middle note by a half step.

And in I Love Coffee, I Love Tea, chord ii has been turned into a major chord by raising its middle note a half step, changing C-flat to C-natural, making the chord II.

V – I chord progression in C

V – I is the strongest chord progression in music. In the key of C, this is chord G (V, dominant) to C (I, tonic).

This strong V – I effect can be extended into a longer, stronger chord progression by circling around a series of chords known as the Circle of Fifths.

The Circle of Fifths usually refers to a chain of similar key signatures. But the same flow can also be used in musical compositions to create very strong chord progressions.

Circle of Fifths — Key Signatures

Chord progression in C

Let’s begin with chords V – I moving from the G chord to C chord.

What would happen if we added a chord before the G chord that’s a fifth above it?

That would be d minor to G, then to C. It sounds really strong! Why? Because, the d minor chord acts like a type of dominant to the G chord. After all, it’s a fifth above.

In the key of C, the ii – V – I progression is d minor – G – C (chord two – chord five – chord one).

But there’s a way to make this chord progression even stronger!

If you change the d minor chord to D Major (by playing F sharp), this is the true dominant of G. So this progression would look like II – V – I, D – G – C. (Cool fact: musicians would say, “Five of five – five – one” — because the D chord is the fifth chord of the fifth chord).

This is why it’s called a circle of fifths chord progression! You take the strongest chord progression and just repeat it down a whole line of chords whose root notes are a fifth apart. It’s okay for some minor chords to be in there, but sometimes it’s fun to turn one into a major chord (a ‘secondary dominant’) because it sounds so strong!

And…this leads us to the reason the chord progression of I Love Coffee, I Love Tea sounds so strong. Chord ii has been turned into a major II chord, and is a true “five of five”!
