Meneer Soemo’s music lesson introduces musical scales, chord structures, and their emotional impacts, emphasizing the differences between major, minor, and minor flat five chords for musical understanding and memorization.
🧠 Starting with the E Major Scale
We begin by examining the E major scale, which follows the familiar pattern of whole and half steps:
Whole – Whole – Half – Whole – Whole – Whole – Half
Applied to E, this gives us the following notes:
E – F♯ – G♯ – A – B – C♯ – D♯ – E
To build a basic chord (triad), we use the 1st, 3rd, and 5th notes of the scale:
- E – G♯ – B → This forms the E major chord, based on the 1–3–5 formula.
🎵 E Minor: Spotting the Difference
Now let’s look at the E minor chord:
- E – G – B
Notice the difference? The third note is G instead of G♯. That small change makes a big difference in sound and mood. The E minor chord uses a flattened third (♭3), which gives it a more introspective or melancholic tone.
🎼 Understanding B Minor and B Minor Flat Five
We also explore the B scale, which follows the same whole/half step pattern:
B – C♯ – D♯ – E – F♯ – G♯ – A♯ – B
Using the 1–3–5 formula:
- B – D♯ – F♯ → This is the B major chord
But what happens when we flatten the third and fifth?
- B – D – F → This is the B minor flat five chord, often written as Bmin♭5 or B–♭5
📚 Summary of Chord Structures
| Chord Type | Formula | Notes | Description |
|---|---|---|---|
| Major | 1 – 3 – 5 | E – G♯ – B | Bright, stable sound |
| Minor | 1 – ♭3 – 5 | E – G – B | Softer, more emotional tone |
| Minor flat five | 1 – ♭3 – ♭5 | B – D – F | Tense, unresolved feel |
🔍 Final Takeaway
The difference between major and minor chords lies in the third note:
- A major third is 4 semitones above the root.
- A minor third is 3 semitones above the root.
- A flat five is 6 semitones above the root instead of 7.

| G♯/A♭ | A♯/B♭ | C | C♯/D♭ | D♯/E♭ | F | G | G♯/A♭ |
| A | B | C♯/D♭ | D | E | F♯/G♭ | G♯/A♭ | A |
| A♯/B♭ | C | D | D♯/E♭ | F | G | A | A♯/B♭ |
| B | C♯/D♭ | D♯/E♭ | E | F♯/G♭ | G♯/A♭ | A♯/B♭ | B |
| Chord Type | Formula | Notes | |
|---|---|---|---|
| C | 1 – 3 – 5 | C – E – G | C |
| Cmin | 1 – ♭3 – 5 | C – E♭ – G | C minor |
| Cminb5 | 1 – ♭3 – b5 | C – E♭ – G♭ | C minor flattened fifth |
Understanding these intervals helps musicians not only play chords but also hear and feel their emotional impact.
