Lesson Outline
Introduction (5 minutes)
-
Greeting and Warm-up
- Welcome students and engage them with a brief discussion about harmony in music.
- Ask students if they have heard the term “triad” before and what they think it means.
-
Objective Overview
- Share the lesson objectives with the class and explain how triads form the basis for much of Western harmony.
Explanation of Triads (10 minutes)
-
Definition of a Triad
- A triad is a three-note chord formed by stacking two thirds on top of a root note.
-
Types of Triads
- Major Triad: Made up of a root, major third, and perfect fifth.
- Minor Triad: Made up of a root, minor third, and perfect fifth.
- Diminished Triad: Made up of a root, minor third, and diminished fifth.
- Augmented Triad: Made up of a root, major third, and augmented fifth.
-
Illustrations on the Board
- Write out each type of triad on the whiteboard, using a C root as an example for each type.
- Use visual aids to illustrate how the notes are stacked in different formations.
Listening Activity (5 minutes)
-
Play Audio Examples
- Play audio examples of each type of triad.
- Encourage students to listen for the differences in sound and character.
-
Class Discussion
- After each example, ask students to describe how each triad sounds and whether they can identify the emotional quality associated with each type.
Practical Activity (10 minutes)
-
Constructing Triads
- Hand out staff paper and pencils.
- Instruct students to choose a root note and draw each type of triad on the staff.
-
Playing Triads
- If resources permit, ask students to find the triads on a piano or keyboard.
- Allow students to work in pairs to help each other identify and play the triads they created.
Conclusion (5 minutes)
-
Review of Key Concepts
- Recap the types of triads covered in the lesson.
-
Exit Ticket
- As an exit ticket, have each student write down one thing they learned about triads and one question they still have. Collect these as they leave.
Assessment
- Formative assessment through class participation and pair work during the practical activity.
- Exit tickets will be reviewed to identify understanding and gaps in knowledge.
Extensions
- For homework, students can explore writing a short piece of music that includes at least three different triads or learn a song that heavily features triadic chords.
Additional Resources
- Online music theory websites that explain triads further.
- Suggested music pieces that utilize various triads for additional practice.
This lesson plan meets the United States educational standards for teaching music theory in a high school setting, focusing on foundational harmonic concepts essential for music literacy.
