Learn Bass Guitar - Scales & Chord Tones - part 1



Sharing buttons:

hi there by now your general awareness

and knowledge of the major scale in

different keys should be in good shape

so in this session I'd like to look at

how the scale links to chords and more

importantly how we can use this

relationship to construct musical ideas

so to begin with let's take a look at

the core tones of the C major scale and

learn a little bit more about the chord

that's associated with this scale if you

remember the chord tones of a scale are

the 1st 3rd 5th and 7th notes now if we

count up through the notes of our C

major scale we can easily work these out

we know that C is the first or root note

is the 2nd the 3rd is an E this is the

4th the 5th is the note G continuing on

to the 6th and here's the 7th note of me

ok so from that we've successfully found

that the chord tones of a C major scale

are the notes C E G and B for this

session though let's just look at the

first 3 chord tones C E and G and

explore these a little deeper we can

take any 3 chord tones of any scale and

create something called a triad as we

progress together we'll learn about

different types of triad and how they

change depending on the scales we're

using this triad we've just discovered

is called a C major triad and the name

should come as no surprise as it's

contained within our C major scale if we

play the 3 notes of a C major triad

together at the same time we create a

chord and this chords name as you've

probably already guessed is the chord of

C major here how we can outline the

overall sound of this chord by playing

the individual notes that

make up the major triad again this

should come as no surprise as its these

notes played together that creates a

major chord

remember as bass players we want to be

able to spell out the sound of any chord

just by using individual notes and to

really get this concept under our bells

we need to learn about intervals as

we've already learned the term interval

is used to describe the distance between

two notes in music so firstly let's look

at the interval between the first two

notes of the C major triad okay here's

our root note of C and the next note in

the Triad is an E now the interval

between these two notes in music is

what's called a major third just take a

look at the layout of these two notes on

the fingerboard and thanks again to the

symmetrical tuning of the bass this

shape is always the interval of a major

third no matter where we choose to play

it but as you're hopefully aware it's

the notes that changes we move the shape

around for example we now know a C - an

E is a major third and moving the shape

we can also see that here's another

major third this time between the notes

of G and B again there's no surprises

why it's called a major third both these

notes are used to form a major triad

which as you now know when played

together create a major chord and if we

link this knowledge back to the scale of

C major the note of E remember is also

the third note in the sequence

now something that I encourage all

students to do is learn how to play

intervals in different ways for example

I've just shown you that the interval of

a major third can be found of one string

and back one fret from any room note

anywhere across the entire fingerboard

but we can also find the same interval

of a major third four frets up on the

same string as our root note like this

I appreciate it's a bit of a stretch yes

but it's still well worth knowing as you

can hopefully see the shapes are

different but importantly they use

exactly the same notes and in this case

it's a C and an E
