If a major interval is raised by a half step, what is the resulting quality?

If a major interval is raised by a half step, what is the resulting quality?

• A. Augmented intervals
• B. Minor intervals
• C. Major intervals
• D. Diminished intervals

Answer: (A)

Raising the upper note by a half step adds one semitone to the interval, so a major interval becomes an augmented version of the same interval. For example, a major third (C to E) is 4 semitones. If you raise E by a half step to E♯, you get C to E♯, which is 5 semitones and labeled as an augmented third. This pattern holds for any major interval: increasing the distance by one semitone turns it into an augmented interval.
