Intervals in music theory refer to the distance between two notes. Understanding intervals is a crucial part of music theory as it helps in creating melodies, harmonies, and chords. In this article, we will discuss how to do intervals in music theory.

The Basics of Intervals

An interval is the distance between any two notes. It is measured in half-steps or whole-steps. A half-step is the shortest distance between two notes on a keyboard, while a whole-step is equal to two half-steps.

Types of Intervals

Intervals are classified into two types: harmonic and melodic. Harmonic intervals are played simultaneously, while melodic intervals are played in succession.

Harmonic Intervals: When two notes are played at the same time, it creates a harmonic interval. For example, when you play C and G together on a keyboard, it creates a harmonic interval of a perfect fifth.

Melodic Intervals: When two notes are played one after the other, they create a melodic interval. For example, when you play C and E one after the other on a keyboard, it creates a melodic interval of a major third.

Interval Quality

The quality of an interval is determined by its size and whether it’s major or minor. The size refers to the number of steps between two notes. Major intervals have a larger size than their corresponding minor intervals.

Interval Names

Intervals are named based on their size and quality. For example, a C to E interval would be called a major third because it’s a third away from C and the distance between C and E is four half-steps, which is the size of a major third.

Conclusion

In conclusion, intervals are an essential part of music theory. Understanding the different types of intervals, their quality, and names can help in creating beautiful melodies and harmonies. Practice identifying intervals by playing them on a keyboard or listening to them in music to improve your music theory skills.
