MUSIC THEORY FOR PRODUCERS INTERVALS – PART 4

In the previous lessons, we have learned about intervals – what they are, why to learn it, and also how to build major and minor seconds and thirds. Today we will continue this journey by learning how to build perfect fourths and fifths.

Fourths and fifths will be always called perfect intervals – never major or minors.

A perfect 4th is a fourth spanning five semitones. There are a few ways to build it:

1) Find the major 3rd and go up one-half step;

2) Go up five half steps from the root note.

The keyboard diagram above shows a perfect 4th. C is the root note, so if we count five half steps, we will find that F is C’s perfect 4th. Also, if you remember the lesson about major 3rd, you will know that E is the major 3rd of C. Then, going up a half step will lead you to C’s perfect 4th (F).

Although it’s possible to count semitones to find any interval (method 2), I strongly recommend you to use method 1, which is basically going from the previous interval to find the one you want. For example, if you want to find any third, go from the major second; if you want to find the perfect 5th, find the perfect 4th first, and so on. Although it can be a little challenging at the beginning, this method will make you recognize and build any interval faster and easier.

Let’s see other perfect 4th examples:

A perfect 5th is a fifth spanning seven semitones. You can build it in a few ways:

1) Find the perfect 4th and go up a whole step;

2) Go up seven half-steps from the root note.

p5

In the keyboard diagram above, C is the root note. If you go up seven half-steps, you will reach G, which is their perfect 5th. You can also find the perfect 4th of C and then go up a whole step, and you will get to G.

If you feel it’s difficult to find any of those intervals, keep practicing. Choose any key from your keyboard and try locating their major 2nd, major 3rd, perfect 4th, and perfect 5th. In a few days, you will be able to build any of those intervals easily.

Practice is the key.

Happy productions!
