1-5 1: Recognize and Play Major and Minor Triads

Key Concepts

Triads are the simplest form of chords, consisting of three notes: the root, third, and fifth. Major and minor triads are the most common types of triads. The difference between them lies in the intervals between the notes.

Major Triads

A major triad is built by stacking a major third and a minor third on top of the root note. The intervals are:

• Root to Major 3rd (4 half steps)
• Major 3rd to Perfect 5th (3 half steps)

Minor Triads

A minor triad is built by stacking a minor third and a major third on top of the root note. The intervals are:

• Root to Minor 3rd (3 half steps)
• Minor 3rd to Perfect 5th (4 half steps)

Recognizing and Playing Triads

To recognize a major triad, listen for a bright and happy sound. Minor triads have a darker and more somber sound. Practice playing these triads on your instrument to internalize their sound and structure.

Examples and Analogies

Think of major triads as sunny days with clear skies, while minor triads are like cloudy days with a hint of melancholy. The difference in intervals creates these distinct moods.

Another analogy is to think of major triads as a strong, confident voice, and minor triads as a softer, more introspective voice. The intervals between the notes give each triad its unique character.

Practical Application

Start by playing the C major and A minor triads on your instrument. Pay attention to the sound and feel of each triad. Gradually expand to other major and minor triads, and try to identify the intervals between the notes. This exercise will help you recognize and play triads accurately.
