How to Analyse Any Song's Harmony in 5 Steps

Tue, 10 Mar 2026 09:00:00 +0000

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.

The Double Harmonic Scale: From Miserlou to Metal

Thu, 05 Mar 2026 09:00:00 +0000

The opening riff of Dick Dale’s “Miserlou” is one of the most instantly recognisable guitar lines in popular music. It races up and down a scale that sounds nothing like major or minor — something urgent, exotic, and slightly dangerous. That scale is the double harmonic, and its distinctive sound has travelled from Middle Eastern and Eastern Mediterranean traditions into surf rock, progressive metal, film scores, and video game soundtracks.

See Your Scales and Chords on the Guitar Fretboard

Sun, 01 Mar 2026 10:00:00 +0000

The Interactive Chord Finder has always shown scale notes and chord tones on a two-octave piano keyboard. That works well if you think in terms of keys, but guitarists think in terms of fret positions and string patterns. Starting today, you can switch to a guitar fretboard view that maps the same musical information across six strings and fifteen frets.

How to Use It

Below the scale selector you will find a small Piano | Guitar toggle. Click Guitar to switch. Your choice is remembered between sessions, so the tool opens in whichever view you used last.

Practice Chord Recognition with the Chord Practice Tool

Mon, 23 Feb 2026 07:06:00 +0000

Knowing which chords belong to a key is one thing. Recalling them instantly under time pressure is something else entirely. Whether you are sight-reading a lead sheet, improvising over a backing track, or composing on the fly, the speed at which you recognise and name chords makes a real difference. That is exactly what the new Chord Practice tool is designed to help with.

What the Chord Practice Tool Does

The practice tool presents diatonic chords one at a time, on a timer, and asks you to identify or play each chord before the next one appears. Think of it as flashcards for chord recognition, but with audio, a metronome, and optional MIDI keyboard input.

You want to know which chords fit in a key. You want to hear them, see them on a keyboard, and maybe build a progression you can play along with. The Interactive Chord Finder does all of that in your browser — no account, no download, no ads. This article walks you through every section of the tool so you can get the most out of it.

Choosing a Key and Scale

At the top of the page you will find two selectors: the root key and the scale.

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.
