Play C and then Am. Can you hear the difference? The first chord sounds bright, like sunshine. The second one sounds softer and a bit thoughtful, like a rainy day. That’s the difference between major and minor.
CAmOne single note makes the difference
A basic chord is made of three notes: the root, a middle note and a top note. C major is C – E – G. In C minor the middle note is one small step lower: C – Eb – G. Just that one note, called the third, decides whether a chord sounds major or minor.
- Major third (4 half steps above the root) → major, symbol with no extra letter: C, G, F
- Minor third (3 half steps) → minor, symbol with an m: Am, Dm, Em
A listening game for two
- One person plays either C or Am while the other one doesn’t look at their hands.
- The other shouts “Sunshine!” for major or “Rain!” for minor.
- Then swap roles. Later, add G and Em or F and Dm.
Chord siblings
Every major chord has a minor partner that shares almost the same notes: C major goes with A minor, G major with E minor, F major with D minor. That’s why these pairs sound so good together and turn up side by side in many songs. The Chord Detective in the app shows you whether a chord is major or minor and which notes it contains.
