What Are Scale/Chord Systems?

Most people might not realize it, but scales have their own built in chord systems. By using the notes from a scale we can make up 7 different chords. We can then use the 7 chords as a blueprint for creating chord progressions. The scale that the chords were built from can be used to create a melody or used to solo over the progression with. We call theses scale/chord systems. The Chord Progression section of the Guitar Alliance Member's Site will show you each scale's chord system, how these chord systems are built, and most importantly how they are used.

If you are interested in writing your own songs, these scale/chord systems are by far one of the most important songwriting tools you'll ever come across. Each chord construted from a scale plays a different role and knowing how they interact with each other will make you a better songwriter. All you have to do is pick the key signature you want your song to be in then you find the correct scale/chord system chart for that key and then you can know exactly what chords and scales will work for your song.

Creating Chord Progressions In The Key Of A Major

To figure out the chord system from a scale you must create triads off of the scale steps. Triads are three notes that spell a chord. There are three triad types that are extracted from scales: major, minor, and diminished (we show you how to do this in the Member's Site).

Note: The 1st, 4th and 5th chords that are built from a scale are the most used chords in popular music. The standard blues progression is made up of these three chords and most early rock songs (rock was spawned from the blues) used these same 3 chords. Not much has really changed as a majority of popular music are still 3 chord songs using mostly the minor 2nd, 3rd, and 6th minimally-usually in bridges or interludes. Keep that in mind when creating your own progressions!

Example

Here is a sample progression built from the A major scale/chord system on this page. You'll notice in this example that chord phrasing is used instead of simply strumming through the chords.You can just strum along if you don't know chord phrasing.
