Extended chords are basic major 7, minor 7 or dominant 7 chords which have other notes added to create a more colourful sound. If we keep stacking thirds onto our 7 chords, we end up with some more notes to include in the chord. These notes are the 9th‘s, 11th‘s and 13th‘s. NINTH CHORDS 9th chords will add the 2nd note of the scale … Read More
In some instances we can flatten or sharpen certain notes in the chords to create even more ‘colour’. A typical use of altered chords is where we want to create a chromatic (or melodic) progression through the harmony. This is used a lot in jazz where altered chords are voiced so that a chromatic melody line will appear through the … Read More
We can make chords out of every note of the major scale by adding triads on to each note in the scale, using only the notes in that scale. For example, if we take the A major scale: We know that the root note (A) becomes an A major chord when we add the 3rd (C#) and 5th (E) notes to it and play them simultaneously. If we … Read More
So what happens if we want to harmonize the (harmonic) minor scale? Lets have a look (the harmonic minor scale is the basis for harmonies in a minor key). As an example we will use the A harmonic minor scale: 1 2 3 4 5 6 7 8 A B C D E F G# A (root) (octave) Notes of … Read More
We can extend the idea of harmonizing the major and (harmonic) minor scales with triads to include four part harmonies. This means each note of the scale will produce a chord consisting of the triad plus a seventh. In any Major key, we get the following 7th chords: The chord built on the 1st note of the major scale is a MAJOR 7thThe chord built on the 2nd note of the major … Read More
To discuss chord progressions, we label each note of a scale with a roman numeral, for example: I II III IV V VI VII VIII A B C D E F G# A (root) (octave) Notes of the A Major Scale I-IV-V PROGRESSIONS By far the most common chord progression in blues, pop and rock music is the I-IV-V progression. This means … Read More
II-V-I PROGRESSIONS II-V-I progressions are commonly used in jazz music, but also can be found in many pop and rock songs. If the progression appears in a jazz context, the chords are often played as seventh chords with extensions and alterations. The II, V and I chords of a key are very good at helping our ears identify the key … Read More
This chord exercise is based on the II-V-I chord progression and spans 12 keys, following the Circle of Fifths anti-clockwise (so after each line the key will change by a fourth). This is a good exercise in finding chords in different keys on the fretboard. Note that, on the last line, we have ended up in the same key we started with … Read More
We can create some more interesting and unusual chord progressions by using major chords which are derived from the major key’s parallel minor scale. This is simply the minor scale that shares the same root note as the major key you are playing in. So, if you were playing a song in the key of G major, the parallel minor … Read More
Sometimes chords can be substituted for others, as long as they remain in the same mode (major, minor or dominant). Usually (but not always) these chords are just extensions of the triad. I SUBSTITUTIONS The I chord is major, and is commonly replaced by a major 7, major 6 or major 9 chord, especially when you have several bars of the same chord and want to make … Read More
