Mastering Guitar Intervals: How to Use and Practice

Intervals are the building blocks of music, shaping chords, scales, and melodies on the guitar. By understanding intervals and how they function, you can unlock new layers of creativity in your playing and gain a deeper understanding of the fretboard. In this blog post, we’ll dive into the fundamentals of intervals, how to practice them on the guitar, and how to incorporate them into your daily practice routines. You’ll also learn how intervals can improve your improvisation, chord construction, and overall musicianship.

What Are Guitar Intervals?

An interval refers to the distance between two notes, measured in half steps and whole steps. Each interval has a unique sound and is fundamental to constructing scales, chords, and melodies. Here’s a quick overview of common intervals and their names:

• Perfect Unison (P1): Same note.
• Minor 2nd (m2): One semitone apart.
• Major 2nd (M2): Two semitones apart.
• Minor 3rd (m3): Three semitones apart.
• Major 3rd (M3): Four semitones apart.
• Perfect 4th (P4): Five semitones apart.
• Perfect 5th (P5): Seven semitones apart.
• Minor 6th (m6): Eight semitones apart.
• Major 6th (M6): Nine semitones apart.
• Minor 7th (m7): Ten semitones apart.
• Major 7th (M7): Eleven semitones apart.
• Octave (P8): Twelve semitones apart​

These intervals form the backbone of both major and minor scales, helping guitarists navigate the fretboard and build melodies and harmonies.

How to Practice Intervals on Guitar

1. Start with Basic Intervals

Begin by practicing intervals on a single string, working up and down the fretboard. For example, if you’re on the E string, play a note on the 5th fret (A), and then move to the 12th fret (E) to play a perfect 5th interval. This exercise helps you develop an ear for the distance between notes and builds muscle memory.

2. Practice Across Strings

Playing intervals across strings rather than just along one string will help you become more comfortable with the layout of the fretboard. For instance, to play a perfect 4th interval starting on the 3rd fret of the A string (C), move to the 5th fret of the D string (F). This method allows for faster playing and more fluid transitions between notes.

Keep in mind that when crossing from the G to the B string, intervals shift by one fret due to the tuning difference, so you’ll need to adjust your finger positioning accordingly​​

3. Apply Intervals to Scales

One of the most effective ways to integrate intervals into your playing is by applying them to scales. When practicing a major scale, for example, focus on the relationships between the root and other notes. The Ionian mode (major scale) is made up of the following intervals:

• Root – Major 2nd – Major 3rd – Perfect 4th – Perfect 5th – Major 6th – Major 7th​

Practice playing each interval in relation to the root, starting with simple scales like G major. This will help you memorize the shape of the intervals and see how they correspond with the fretboard.

4. Practice Diads and Chord Construction

A diad is a chord built from two notes, often constructed using intervals such as thirds or fifths. Practicing diads is an excellent way to incorporate intervals into rhythm guitar playing. For example, playing a C on the 3rd fret of the A string with an E on the 2nd fret of the D string creates a major 3rd interval. Try incorporating diads into your practice by moving between different intervals and creating harmonies​

Using Intervals in Improvisation

Understanding intervals unlocks new possibilities in improvisation, allowing you to move beyond simply playing scales. For example:

• When soloing over a minor chord, you might highlight the minor 3rd and perfect 5th to emphasize the chord’s tonality.
• Use octaves to create melodies that sound fuller and more dramatic, similar to the playing style of guitarists like Wes Montgomery​
