Lesson 2—Intervals

This second lesson will cover two different kinds of intervals—the perfect and major intervals. Below are some intervals.

Description: C Intervals

As you can see, these intervals are called prime, second, third, fourth, etc., because of the distance between the two notes.

Let us look at the fifth interval.

Fifth Interval

By counting C and G and the lines and spaces or notes between C and G we see that there are five notes, therefore it is an interval of a fifth.

Below are different kinds of intervals that are found in music. They are written in the C scale but can be found in any music scale.

Types of Intervals

After examining the chart, fill in the following blanks.

There are only four perfect (sounding somewhat open and thin) intervals.

They are the p_____, f_____, f_____ and o_____.

The major intervals are the s_____, t_____, s_____, and s_____ intervals. An interval is major if the upper note may be found in the major key of the lower note.

Find these major intervals from the previous illustration and fill in the spaces.
