Music Theory 101: Intervals
You know about seconds. But of course, those aren’t the only gaps between notes. While seconds describe the change between two adjacent notes, you can also go further by describing the jump of two notes, three , and so on.
Let’s look at our scale again:
Do Re Mi Fa So La Ti Do
It’s the major scale, because it begins with Do. Now, as we know, Do-Re is a second. Do-Mi therefore, is called a third. Followingly, the other intervals:
Do-Fa: Fourth
Do-So: Fifth
Do-La: Sixth
Do-Ti: Seventh
Do-Do: Octave
Try playing the intervals on your instrument, using the C-major key (Do is C, Re is D etc.).
All music is made up of intervals. As we know about major and minor seconds, there are variations of these for other intervals as well. But in a major scale, all intervals are major except the two minor seconds (Mi-Fa and Ti-Do).
In the next lesson, we’ll explore the Third.
