How To Decipher The I Iv V Chord Pattern

Before you learn how to form certain chords you must first learn about scales. A scale is a series of notes that go in an ascending and descending manner. For every scale (major or minor) there are 7 notes, for example in the key of C the notes are C - D - E - F - G - A - B. The 8th note (in this example will be C) goes back to the root note but an octave higher.

Each note of a scale has a corresponding number from 1 to 7. So for the key of C it will be as follows:

C = 1D = 2E = 3F = 4G = 5A = 6B = 7

In order to make a major triad, you will play the 1st + 3rd + 5th notes of a major scale. In our example it is C - E - G, that’s the C major chord.

Let’s have another example this time using the C minor scale:

C = 1D = 2Eb = 3F = 4G = 5Ab = 6Bb = 7

In order to make a minor triad, you will play the 1st + 3rd + 5th notes of a minor scale. In our example it is C - Eb - G, that’s the C minor chord.

Note: For the next entry we will omit the 7th and 8th notes to make it less confusing.

Roman Numerals

Sometimes instead of numbers, Roman Numerals are used. We go back to our example and use a Roman Numeral for each note in the key of C:

C = ID = iiE = iiiF = IVG = VA = vi

Roman numeral I refers to the chord built on the first note of the C major scale. Roman numeral II refers to the chord built on the second note of the C major scale, and so on. If you notice, some of the Roman numerals are capitalized while others are not. Uppercase Roman numerals pertain to a major chord, while lowercase Roman numerals pertain to a minor chord. Uppercase Roman numerals with a (+) symbol refer to an augmented chord. Lowercase Roman numerals with a (o) symbol refer to a diminished chord.

The I, IV, and V Chord Pattern

For each key, there are 3 chords that are played more than others known as “primary chords.” The I - IV - V chords are built from the 1st, 4th and 5th note of a scale.

Let’s take the key of C again as an example, looking at the illustration above, you will notice that note I on the key of C is C, note IV is F and note V is G.

Therefore, the I - IV - V chord pattern for the key of C is:C (note I) = C - E- G (1st + 3rd + 5th note of the C scale)F (note IV) = F - A - C (1st + 3rd + 5th note of the F scale)G (note V) = G - B - D (1st + 3rd + 5th note of the G scale)

There are many songs that have been written using the I - IV - V chord pattern, “Home on the Range” is one example. Practice playing the I - IV - V chord pattern for every major key and listen to how it sounds as this might inspire you to come up with a great melody for your song.

Here’s a handy table to guide you.
