Quadrium - Music Theory Series Part 4 - Introduction to Scales 1 SI Lesson
Hello. Welcome to my Music Theory Series. In todays lesson we will take a look at the scales. Let’s begin.
A scale is a sequence of musical notes in ascending and descending order that provides material for or is used to conveniently represent part or all of a musical work including melody and/or harmony.
It is important to remember a scale pattern on the guitar, if you know the pattern of a particular scale, you can move that pattern anywhere else on the fret board and be playing in a different key. By this, I mean if you are playing a major scale, beginning on the low E string at the fifth fret, which is an A note and then you played the same pattern of notes, but you started on the 3rd fret of the low E string, you will be playing a G major scale.
Now let’s take a look at scale types.
-Melodic Minor Scale
-Harmonic- Minor Scale
-Whole Tone Scale
-I’ve covered the major/minor and pentatonic scales in my previous lessons.You can find them in those links:
Now let’s continue with the Blues Scale:
A Blues scale consists of six notes.(minor pentatonic scale plus #4th,b5th degree) A major feature of the blues scale is the use of blue notes.So what are those blue notes?Let’s see:
A blue note is a note sung or played at a slightly lower pitch than that of the major scale for expressive purposes.(b3,#4/b5 and b7 degrees of a scale.))
Though the blues scale has an minor tonality, it is commonly 'forced' over major-key chord changes.
Now that we know how to construct a blues scale,let’s construct one.
Let’s say we want to construct a A Blues Scale.As i mentioned before we need a pentatonic scale plus #4th/b5th degree to construct a Blues scale.So:
A minor pentatonic scale:
A C D E G
Now we need a diminished 5th/augmented 4th note. The fifth degree of A minor scale is a E note.Then the diminished 5th/augmented 4th is a Eb/D# note.If we add this note to our A minor Pentatonic Scale we get the A Blues Scale.
A C D D#/Eb E G
A Blues Scale All Patterns:
The constructing way is same for every scale.To sum up here are the steps to construct a Blues Scale:
1-Find the minor pentatonic scale of the given scale.
2-Find the Diminished 5th/Augmented 4th degree of the given scale.
3-Add the Diminished 5th/Augmented 4th note to the minor pentatonic scale you have found before.
That's it. You have a Blues Scale now.
Now that we have covered Major Scale,Minor Scale,Pentatonic Scale and Blues Scale. We will continue covering other scales in next lesson.
See you there.Keep rocking.
