Types of Intervals in Music Theory
Intervals are an essential part of music theory that describes the distance between two pitches or notes. An interval is the smallest unit of measurement that creates harmony between two notes. It is a fundamental aspect of music theory that enables musicians to produce well-organized and structured music.
Intervals can be classified into different types based on their characteristics. These classifications enable musicians to understand the nature of the intervals and use them creatively in their compositions. In this article, we will discuss the various types of intervals in music theory.
1. Melodic Intervals
Melodic intervals refer to the distance between two consecutive notes played separately. These intervals determine the melody and can be either ascending or descending.
- Ascending intervals: These are intervals that move upward in pitch from a lower note to a higher note. For example, if you play a C note and then play a D note, you’ve created an ascending interval of a second.
- Descending intervals: These intervals move downward in pitch from a higher note to a lower note. For example, if you play a D note and then play a C note, you’ve created a descending interval of a second.
Melodic intervals are further classified into various types based on the number of intervals between two notes. These include:
- Second: This is the interval between two adjacent notes. For example, the interval between C and D is a second.
- Third: This interval is created by skipping one note between two notes. For example, the interval between C and E is a third.
- Fourth: The interval between two notes separated by three notes is fourth. For example, C to F is a fourth.
- Fifth: This interval is created by skipping four notes. For example, C to G is a fifth.
- Sixth: The interval between two notes separated by five notes is sixth. For example, C to A is a sixth.
- Seventh: This interval occurs when two notes are separated by six intervals. For example, C to B is a seventh.
- Octave: This interval is the distance between two notes of the same letter name. For example, C to C is an octave.
These intervals are further classified into major, minor, augmented, and diminished intervals based on the distance between the two notes in semitones. The table below summarizes the different types of melodic intervals.
| Interval | Semitones | Name |
|---|---|---|
| Unison | 0 | Perfect unison |
| Second | 1 | Minor second |
| Second | 2 | Major second |
| Third | 3 | Minor third |
| Third | 4 | Major third |
| Fourth | 5 | Perfect fourth |
| Augmented Fourth | 6 | Augmented fourth / diminished fifth |
| Fifth | 7 | Perfect Fifth |
| Sixth | 8 | Minor sixth |
| Sixth | 9 | Major sixth |
| Seventh | 10 | Minor seventh |
| Seventh | 11 | Major Seventh |
| Octave | 12 | Perfect octave |
Interestingly, the smallest interval used in Western music, a semitone, was considered unimportant, and its existence was unknown to the ancient Greeks. It was only recognized during the 9th century. Also, the term semitone is used due to the mathematical division of an octave, while in Indian music, the smallest interval used is a Shruti, which is roughly equal to a quarter of a Western semitone.
In conclusion, understanding intervals is essential for any musician, and these different classifications can help create unique and creative compositions. Through practicing, musicians can master these intervals and use them effectively to create an emotional impact on their audiences.
Why Understanding Intervals is Important in Music Education
Music education not only enriches one’s life but also develops cognitive abilities and socio-emotional competencies. To be a musically literate individual, one must not only learn how to play an instrument or read sheet music but also have a good understanding of the fundamentals of music theory. One of the basic components of music theory is intervals. Intervals are the distances between two notes, and they are vital in music education.
Understanding intervals can take your musical abilities to the next level, and in this section, we outline why this is so important.
Intervals Help with Sight Reading and Sight Singing
The sight reading and sight singing skills are fundamental to music theory. Sight reading refers to reading sheet music at first sight and being able to play or sing it immediately. Sight singing, on the other hand, is about reading sheet music and singing it on pitch without actually hearing it played. Understanding intervals helps music students sight read and sight sing with ease because intervals represent the distance between two notes. A musician who understands intervals can identify the interval between two notes on the fly, and this makes sight reading and sight singing much easier.
Intervals Help with Transposition
Transposition is the process of changing a piece of music from one key to another. This technique is used to give a different tonality to a piece of music and to fit the range of another instrument or vocalist. Understanding intervals is essential for transposition because transposition involves adjusting the intervals between the notes in the chords to a new key.
For example, in the key of C Major, the notes that make up the C Major chord are C, E, and G. If you were to transpose this chord to the key of D Major, you would need to adjust the intervals between the notes to to D, F#, and A. Musicians who understand intervals can easily recognize the new intervals needed to transpose the chord to the key of D.
Intervals Help with Chord Progressions
A chord progression is a succession of chords played in a specific order. Understanding intervals is crucial for chord progressions because chords are made up of intervals between notes. For example, a major chord is made up of a major third and a perfect fifth interval between the root note and the other two notes of the chord.
By understanding the intervallic structure of chords, music students can create or analyze chord progressions with ease. They can also create their unique chords and progressions by using intervals in creative ways for their music.
Intervals Help with Ear Training
Ear training is learning to recognize melodies, chords, and intervals by ear. Ear training is essential for improvisation, transcription, and arrangement of songs. Understanding intervals and the relationships between them is crucial for ear training because its the foundation for identifying musical patterns and recognizing melodic and harmonic structures.
Music students who are proficient in ear training are great improvisers who can identify the intervals by ear in melodies and chord progressions.
Intervals Help with Music Composition
Music composition involves the creation of a musical piece. To create music in a structured and organized manner, music composers must understand the fundamentals of music theory, including intervals. A piece of music has a specific melody, harmony, and rhythm that depends on the intervals used.
The understanding of intervals allows music composers to create melodies and harmonies based on the intervals required and create variations such as chord inversions, chord progressions, and more. With a solid understanding of intervals, composers can create music that engages and resonates with the audience.

How to Identify Intervals in Music by Ear
Identifying the intervals in music by ear is one of the fundamental skills every musician should have. To be able to play and write music proficiently, one must understand the intervals and their relationship with the melody and harmony. In this section, we will learn how to identify intervals in music by ear.
Understanding the Basics of Intervals
An interval is the distance between two notes in music. It can be measured in half steps or whole steps. A half step is the distance between two adjacent keys on a piano. For example, C to C# is a half step. A whole step is two adjacent half-steps. For example, C to D is a whole step.
Intervals can be classified according to their numeric value and quality. The numeric value tells us how many notes are involved in the interval, while the quality describes the sound of the interval. There are four qualities of intervals: perfect, major, minor, and diminished.
To identify the intervals, you need to be familiar with the sound of each interval quality. Perfect intervals are the most common and stable intervals in music. They have a consonant and harmonious sound. The most common perfect intervals are the unison, fourth, fifth, and octave. Major intervals are the next most common intervals. They have a brighter and more uplifting sound. Minor intervals have a darker and more melancholic sound. Diminished intervals have a dissonant and tense sound.
Using Mnemonic Devices
One of the most effective ways to identify intervals is through the use of mnemonic devices. Mnemonic devices are memory aids that help you remember information. There are several popular mnemonic devices that can help you identify intervals, such as:
- The “TWINKLE, TWINKLE” method: This method uses the first two notes of the popular nursery rhyme to identify the intervals. The first interval is a perfect fifth (C-G), the second interval is a perfect fourth (G-C), and the third interval is a major third (C-E).
- The “OH MY ACHING HEAD” method: This method uses the first letters of each word to identify the intervals. The first interval is an octave (O), the second interval is a major second (M), the third interval is a minor third (A), and so on.
- The “MY DOG HAS FLEAS” method: This method uses the first letters of each word to identify the intervals. The first interval is a major sixth (M), the second interval is a perfect fourth (D), the third interval is a major third (H), and so on.
Practicing Ear Training Exercises
Ear training exercises are essential to develop your ability to identify intervals by ear. There are several ear training exercises you can practice, such as:

Interesting Fact:
The concept of intervals dates back to Pythagoras in ancient Greece. He discovered that the relationship between the lengths of vibrating strings on musical instruments corresponded to musical intervals.
The Relationship Between Intervals and Chords in Music
Music is not just the notes played by an instrument, but also the relationship between these notes. Intervals and chords form the basis of this relationship. Understanding how they work together can help a musician create a more harmonious and pleasing sound.
What are Chords?
A chord is a group of three or more notes played together. This creates a sound that is richer and more complex than a single note. Chords can be major or minor and are made up of intervals.
Imagine you are playing a C major chord on a piano. The chord consists of the notes C, E, and G played together. The interval between C and E is a major third, while the interval between E and G is a minor third. These two intervals together form a major chord.
It is important to note that chords can be inverted. This means that instead of playing the notes in their original sequence, they can be rearranged. For instance, a C major chord with its root note as C can be inverted as E-G-C or G-C-E.
How do Intervals Work with Chords?
Intervals refer to the distance between two notes in music. They play a crucial role in the creation of chords. Major and minor chords are built from a combination of intervals.
Major chords are formed by combining a root note, a major third, and a perfect fifth. For example, a C major chord comprises the notes C (root note), E (major third), and G (perfect fifth). The interval between the root note and the major third is a major third, while the interval between the major third and the perfect fifth is a minor third.
In contrast, minor chords are formed by combining a root note, a minor third, and a perfect fifth. For example, an A minor chord comprises the notes A (root note), C (minor third), and E (perfect fifth). The interval between the root note and the minor third is a minor third, while the interval between the minor third and the perfect fifth is a major third.
It is possible to create a variety of chords by combining different intervals in various sequences. For instance, a seventh chord is formed by adding a minor seventh interval to a major chord. A ninth chord comprises of five notes, namely the root note, a major third, a perfect fifth, a minor seventh, and a ninth.
Why are Intervals and Chords Important?
Understanding intervals and chords is important because they are the building blocks of music. They help create pleasing melodies and harmonies that can evoke emotions in an audience.
For instance, a major chord is often described as sounding happy or joyful, while a minor chord is associated with sadness or melancholy. By manipulating the intervals within a chord, a musician can create different moods and atmospheres in their music.
Chords are also essential in forming progressions. Progressions are the succession of chords played together in a piece of music. They create the structure and backbone of a song. Certain progressions, such as the I-IV-V progression, are commonly used in many genres of music.
Pros and Cons of Using Intervals and Chords
