What are the differences between major and minor chord progressions in music theory?

Major chord progressions are generally considered to have a more uplifting and happy sound, while minor chord progressions tend to sound more melancholic or sad. The difference lies in the intervals between the notes in each chord, with major chords having a major third interval and minor chords having a minor third interval. This distinction in intervals gives major and minor chord progressions their distinct emotional qualities in music.
