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:
In written music:
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.
I Love Coffee, I Love Tea is in the key of G-flat major.
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.
I Love Coffee, I Love Tea Chords in G-flat.
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.
Here is the duet notated in music:

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 wasn’t the lower case ii (minor) but the upper case II (major).
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.
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”!
