Piano Chords Explained: Why Every Key Has the Same 7

Four chords — C, G, A minor and F — turn up in an absurd number of songs. This video is about where they come from, and why one of the four is always minor. No memorising chord charts. We start with a single major chord and count the gaps inside it, discover that a major chord is one shape rather than a list of notes, then find out that moving one finger by one key is the entire difference between major and minor. From there we build all seven chords in the key of C from nothing but the white keys and a rule about skipping notes — and the major/minor pattern turns out not to be a rule at all, but a consequence of where the semitones sit on a keyboard. Then we play the famous four, reorder them, and rebuild the same progression in G to show that the pattern belongs to the key, not to the letters. Everything you hear is a real sampled piano, and every chord you see lit up is the chord you're hearing. ⏱ CHAPTERS 0:00 The four chords 0:25 What we are going to build 0:49 What a semitone actually is 1:06 Four, then three 1:21 Move the shape, keep the gaps 1:49 Why A minor is different 2:13 One key, one semitone 2:41 The C major scale 3:04 Build a chord on every note 4:03 All seven chords in the key of C 4:19 Why the pattern isn't a rule 4:55 The famous four: I - V - vi - IV 5:40 The same four in G 6:06 What to practise 6:19 What you now know 🎹 KEEP GOING Skoove is the piano app I use to keep learning — it listens to what you play and gives feedback in real time, so you're building chords on a real keyboard from lesson one instead of watching someone else do it. https://www.skoove.com/#a_aid=learnpi...
