How to Play

The Chord Reading game shows you a chord on the staff and asks you to identify it in two steps.

1

Read

Look at the notes stacked on the staff. Identify the bottom note — that's the root of the chord.

2

Select Root

Click the root note button (C, D, E, F, G, A, or B).

3

Select Quality

Click the chord type (Major, Minor, Dim, Aug). Your answer is checked automatically.

4

Learn

Wrong answers reveal the correct chord. Click "Hear Chord" anytime to connect the notation with its sound.

Chords on the Staff

A chord appears as stacked notes sharing a single stem. In root position, the notes are spaced in thirds — each note sits on the next line or space above the previous one.

Triads (3 notes)

Three notes stacked in thirds. All root-position triads look similar — three noteheads each a third apart. The accidentals tell you the quality.

Seventh Chords (4 notes)

Four notes stacked in thirds. The extra note on top adds richness. Look for accidentals on the 3rd, 5th, and 7th to determine the type.

Key insight: In root position, the bottom note is always the root. Read it first, then check the other notes for sharps or flats to determine the chord quality.

Identifying Chord Quality

The quality of a chord is determined by the intervals between its notes. Here's what to look for:

Major

Root + Major 3rd + Perfect 5th

R - M3 - P5

No unexpected accidentals on natural roots (C, F, G). Sharps appear on the 3rd for D, E, A, B roots.

Minor

Root + Minor 3rd + Perfect 5th

R - m3 - P5

The 3rd is one half step lower than major. Look for a flat on the 3rd (or absence of the sharp you'd expect).

Diminished

Root + Minor 3rd + Diminished 5th

R - m3 - d5

Both the 3rd and 5th are lowered. Two flats (or missing sharps) is a strong indicator.

Augmented

Root + Major 3rd + Augmented 5th

R - M3 - A5

The 5th is raised by a half step. Look for a sharp on the top note that you wouldn't normally expect.

Seventh Chords (Advanced)

Major 7th

Major triad + Major 7th

R - M3 - P5 - M7

Minor 7th

Minor triad + Minor 7th

R - m3 - P5 - m7

Dominant 7th

Major triad + Minor 7th

R - M3 - P5 - m7

Tip: Dominant 7th has a major 3rd but a flatted 7th — it's the "mixed" one. If the chord looks major but the 7th is lowered, it's dominant.

Difficulty Levels

Beginner

  • Major and Minor triads only
  • Focus on the 3rd interval
  • The most fundamental distinction

Intermediate

  • Adds Diminished and Augmented
  • 4 chord types total
  • Pay attention to the 5th as well

Advanced

  • Adds Major 7th, Minor 7th, Dominant 7th
  • 7 chord types total
  • Read all four notes carefully

Tips for Success

  • Read bottom-up — always identify the root (bottom note) first, then work upward.
  • Look for accidentals — sharps and flats next to the noteheads are the key to determining chord quality.
  • Learn the patterns — C Major (C-E-G) has no accidentals. D Major (D-F♯-A) has one sharp. Memorize common chords.
  • Use "Hear Chord" — connecting the visual pattern with the sound reinforces both skills.
  • Start with treble clef — master one clef before switching to bass or both.
  • Focus on the 3rd — the 3rd degree is what distinguishes major from minor. Train your eye to spot it quickly.
  • Build your streak — aim for consistency over speed. Accuracy improves with practice.
