Chord Identification Tutorial
Learn to recognize chord types by their sound. This guide covers how chords are built, what they sound like, and how to tell them apart.
How to Play
The Chord Identification game plays a chord and asks you to identify its type (Major, Minor, etc.).
Listen
Click "Play Chord" to hear a chord. Choose Block (all at once) or Arpeggio (one note at a time).
Identify
Select the chord type from the answer buttons. The hint text below each button describes the chord's feel.
Replay
Need another listen? Click "Replay" as many times as you like before answering.
Learn
Wrong answers reveal the correct chord type. Over time you'll develop an instinct for each chord quality.
What Is a Chord?
A chord is three or more notes played together. The most basic chords are triads — three notes stacked in intervals of a third. The type of thirds used determines the chord's quality and emotional feel.
Chord Types
Triads (3 notes)
Major
Happy, bright, stable
Minor
Sad, dark, introspective
Diminished
Tense, unstable, spooky
Augmented
Dreamy, mysterious, floating
Seventh Chords (4 notes)
Major 7th
Lush, sophisticated, dreamy
Minor 7th
Mellow, jazzy, smooth
Dominant 7th
Bluesy, tense, wants to resolve
Key insight: Major and minor triads differ by just one note — the third. Major has a major 3rd (4 half steps), minor has a minor 3rd (3 half steps). This small change completely transforms the mood.
Play Styles
Block
All notes at once. Focuses on the overall chord color and mood.
Arpeggio
Notes played one at a time. Helps you hear each individual note within the chord.
Tip: Start with Block mode to learn each chord's overall feel. Switch to Arpeggio when you want to understand the internal structure of the chord.
Difficulty Levels
Beginner
- Major and Minor only
- Focus on happy vs. sad
- The most fundamental distinction
Intermediate
- Adds Diminished and Augmented
- 4 chord types total
- All four basic triads
Advanced
- Adds Major 7th, Minor 7th, Dominant 7th
- 7 chord types total
- Requires hearing the 4th note
Tips for Success
- Start with Major vs. Minor — this is the most important distinction. Think "happy vs. sad."
- Listen for the third — the third note above the root defines the chord quality more than anything else.
- Use arpeggio mode to break down chords you find confusing. Hearing each note separately clarifies the structure.
- Diminished sounds "crunchy" — it has a noticeably tense, compressed quality.
- Augmented sounds "floaty" — like something unresolved and suspended in air.
- 7th chords are "fuller" — they have a richer sound with more complexity than simple triads.
