Part 5: Understand the chords you already hold · Lesson 042 / 117
Practice stop: two familiar triads in time
Practice stop — no rushConnect chord understanding to a relaxed strumming pattern.
Use C and Am, both of which you can now describe by their notes. C contains C–E–G; Am contains A–C–E. Two ingredients, C and E, are shared, while G and A distinguish the collections.
Strum C for one four-beat bar, then Am for one. First use one attack per bar; then try four quarter-note attacks. Keep naming the chord's ingredients as a separate slow exercise rather than forcing a spoken analysis into the performance.
Pick the shared C and E in each grip. Listen to how the surrounding chord changes their context. We will later give precise names to those changing roles. Today, simply identify what stays and what changes.
Finish by playing the passage after a short pause. If your counting suffers, simplify the strum. If naming suffers, stop the rhythm and inspect one chord. These are connected skills, but they need not be mastered simultaneously.

A concrete example
C | Am | C | Am. Shared note names: C and E. C uses G; Am uses A.

Try it, slowly
- Strum once per bar for four bars.
- Pick and name each chord separately.
- Return to the progression with quarter-note strums and keep the four-beat count.
Check one idea
Which note names are shared by C major and A minor?
Show the explanation
C and E. C major adds G to those; A minor adds A. Sharing notes does not make the two chord names interchangeable.
A good place to stop
You can keep time and explain the two chords in separate, comfortable passes.
Return to the example after a short break. A clear explanation matters more than speed.
