What interval exists between the notes C and E?

The interval between the notes C and E is a major third. To understand why this is the case, it's important to consider the distance between the two notes in terms of half steps or semitones.

Starting from C, the notes ascend as follows: C to C# is one semitone, C# to D is another semitone (making two), and D to D# adds a third semitone. Finally, D# to E is the fourth semitone. Therefore, moving from C to E involves four semitones in total, which defines a major third interval.

In music theory, intervals are classified according to the number of semitones they contain. A major third specifically consists of four semitones, distinguishing it from other intervals such as a minor third, which would only have three semitones, or a perfect fifth, which encompasses seven semitones. Recognizing these distinctions is crucial for identifying intervals accurately in music.
