What is the difference between major and minor chords?
A major chord uses a major third (4 semitones) between root and third, giving a bright sound. A minor chord uses a minor third (3 semitones), giving a darker sound. The fifth (7 semitones from root) is the same in both.
What is a chord inversion?
An inversion changes which note is lowest. Root position has the root at the bottom. First inversion has the third at the bottom. Second inversion has the fifth. Use the voicing selector above to explore inversions.
