What Are Intervals and How to Identify Them by Ear

Sun, 15 Mar 2026 09:00:00 +0000

Every melody you have ever hummed, every chord you have ever played, and every harmony that has ever moved you is built from one fundamental ingredient: intervals. An interval is simply the distance between two notes. Learn to hear and name intervals and you unlock the ability to figure out melodies by ear, understand why chords sound the way they do, and communicate musical ideas with precision.

What Exactly Is an Interval?

An interval measures the pitch distance between two notes. When you sing the first two notes of “Happy Birthday” — the jump from the repeated note up to the higher one — you are singing an interval (a major second, as it happens). Intervals can be melodic (two notes played one after the other) or harmonic (two notes played simultaneously).

How to Analyse Any Song's Harmony in 5 Steps

You hear a song that moves you — something about the chords creates a feeling you want to understand and eventually recreate in your own music. But staring at a chord chart and asking “why does this work?” can feel overwhelming without a system. The good news is that harmonic analysis follows a clear process, and once you have the steps down, you can decode the harmony of virtually any song in any genre.

How to Transpose a Song to Any Key

A vocalist finds the perfect song but cannot reach the highest notes. A guitarist wants to jam with a saxophone player whose chart is in a different key. A songwriter finishes a verse in D major and realises the chorus works better in E. All three need the same skill: transposition — moving a piece of music from one key to another while keeping every melodic and harmonic relationship intact.

Chord Progressions Every Musician Should Know

Sun, 15 Feb 2026 10:10:00 +0000

A chord progression is the harmonic engine of a song. It determines the emotional arc, the sense of movement, and the feeling of tension and release that keeps listeners engaged. While there are infinite possible combinations of chords, a handful of progressions appear so frequently across genres and decades that every musician should know them by heart.

This guide covers the most essential chord progressions, explains why they work, and points you to famous songs that use each one.

The Circle of Fifths Explained: Your Key to Understanding Music

Sun, 15 Feb 2026 09:10:00 +0000

The circle of fifths is one of the most elegant and practical tools in music theory. At first glance it looks like a simple clock diagram, but it encodes deep relationships between all twelve keys, their key signatures, and their relative minor counterparts. Once you understand it, you will find it easier to read sheet music, transpose songs, write chord progressions, and communicate with other musicians.

What Is the Circle of Fifths?

The circle of fifths is a visual arrangement of all twelve major keys (and their relative minors) around a circle. Moving clockwise, each key is a perfect fifth above the previous one. Moving counterclockwise, each key is a perfect fourth above — or equivalently, a perfect fifth below. The result is a map that shows exactly how keys are related to one another.
