How to Form a Minor Chord: To form a minor chord, combine the 1st, flat 3rd and 5th tones of the major scale. For instance, to form a C minor chord, start with the C major scale and play note 1, C, the flat 3rd, Eb (1 semitone lower than E) and note 5, G. C-Eb-G is a Cm chord (C minor chord). #piano #pianolesson #musictheory #chords #pianotutorial | Piano-Keyboard-Guide.com
