Now, the Minor 7 Scale. 2 2
This is sometimes called the Dorian scale. 3 3
Again, don't worry about why for 4 4
now, but you will come across this term in Jazz books so it's worth mentioning. 5 5
This is used over a minor chord that occurs within a major key. 6 6
So if you look at the key of C. 7 7
[SOUND] You know it has a family of chords. 8 8
C major 7, D minor 7, E minor 7, and so on. 9 9
This minor 7 scale is used over the minor chord built on the second chord in 10 10
the family of chords. 11 11
So that's [SOUND]. 12 12
And C would be used over the D minor 7. 13 13
And the scale would be all the white keys from D to D. 14 14
[MUSIC] 15 15
It's called a Dorian. 16 16
[MUSIC] 17 17
And the reason you would use this scale a lot is because the second family chord in 18 18
a key is played a lot. 19 19
It very often leads back to the tonic chord using the circle of fifths. 20 20
So, you very often play D minor seven, G seven, back to the tonic. 21 21
So, how do we memorize this minor seven scale? 22 22
There are two ways. 23 23
One way would be to think in terms of a flattened 3rd and 24 24
flattened 7th of a major scale. 25 25
So instead of playing it in D minor, let's say, we wanted to play a C minor 7 scale. 26 26
So, if you play a C major scale. 27 27
[MUSIC] 28 28
And then, if you flatten the 3rd. 29 29
1, 2, 3, and the 7th, 30 30
that's a minor 7 scale. 31 31
[MUSIC] 32 32
Okay, so you would play that over C minor 7. 33 33
[MUSIC] 34 34
So basically it's just [SOUND]. 35 35
There's the major scale, and you flatten the third in the seven. 36 36
[SOUND] Got the minor 7 scale. 37 37
And a second memory trick for 38 38
a minor 7 scale is similar to how you formed the natural minor scale. 39 39
So if you remember that a minor 7 scale also has a close relation to a major 40 40
scale, this time it's a whole tone or two half tones to the left. 41 41
So, if you look again at the C minor 7 scale 42 42
[MUSIC] 43 43
Notice that it's got two flats, B flat, [SOUND] and E flat. 44 44
[MUSIC] 45 45
Now if you go a whole tone which is two half steps, two half tones left of C. 46 46
[SOUND] And play a major skill based on that tone. 47 47
[MUSIC] 48 48
Okay, you'll see that that's the major scale of B flat. 49 49
It's got two flats exactly the same, B flat and E flat. 50 50
[MUSIC] 51 51
So, these two scales are described as close relatives. 52 52
In fact, they contain the exact same notes but they just start on a different key. 53 53
So B flat starts on B flat, B flat major scale. 54 54
[MUSIC] 55 55
C minor seven has exactly the same notes but it starts on the C instead. 56 56
[MUSIC] 57 57
So, both have the same note. 58 58
So, if you have a C minor 7th chord in left hand 59 59
[MUSIC] 60 60
You can actually play the scale of C minor 7 or B flat over same notes. 61 61
[MUSIC] 62 62
There's B flat. 63 63
[MUSIC] 64 64
Let's look at another example. 65 65
D minor 7 scale. 66 66
So the trick is, that D minor 7 is a close relation to the major scale 67 67
a whole tone or two half tones to the left of the root of the scale. 68 68
So you want to play a D minor seven scale, the written note is D, 69 69
so you go a whole tone left, and play a major scale on that note. 70 70
[MUSIC] 71 71
So that's all the note on the D minor 7 scale, but you start on D. 72 72
[MUSIC] 73 73
So, let's try an F minor 7 scale. 74 74
So, you want to know the notes for F minor 7 scale, starting on F. 75 75
And you remember that it's got a close relation to major scale, 76 76
two half tones left. 77 77
So, a major scale built on E flat. 78 78
[MUSIC]. 79 79
Okay, three flats. 80 80
B flat, E flat and A flat. 81 81
So, that's the notes for the F minor 7 scale. 82 82
[MUSIC] 83 83
Same notes just starting on a different point. 84 84
So, hopefully your starting to understand that the easiest way to see how 85 85
it works is to try the D minor seven scale first, which is all the way from D to D. 86 86
[MUSIC] 87 87
Because it's easy to see where those notes come from, 88 88
they come from the C major scale. 89 89
[MUSIC] 90 90
All the way, no, but if you play from D to D. 91 91
[MUSIC] 92 92
That's the D minor seven scale, so 93 93
you can see that its relation is to the C major scale. 94 94
[MUSIC] 95 95
Which is two half tones to the left, so any scale you can do that with.
