This is the 5th episode of my small series "music theory in 5 minutes" which is a series that will try to teach as much music theory as I can, in short, 5-minutes videos.
In this episode, we see a different kind of triads (chords of 3 notes). We see the difference between major chords, minor chords as well as augmented and diminished chords.
We also cover how to find the chords that fit a scale.
This is also an introduction to intervals (3rd and 5th), degrees and the dominant, subjects will cover more in details in later videos
