Question: what is the difference between a major third and a minor third?
Answer: A minor interval has one less semitone than a major interval. For example: since C to E is a major third (4 half steps), C to Eb is a minor third (3 half steps). For example: since C to E is a major third (4 semitones), C to Eb is a minor third (3 semitones). ... Major intervals can be augmented by adding a semitone.
