AI Summary

In this concise tutorial, a jazz musician explains three essential scales all great jazz players know: the diminished scale, the minor pentatonic scale, and the blue scale. He demonstrates each scale on piano, shows how to use them over chords, and reveals a bonus 'secret blue scale' with a major third for added flexibility.

[0:00]
Three essential scales introduced

The video covers the diminished, pentatonic, and blue scales, which are indispensable for jazz musicians.

[0:44]
Diminished scale structure

This is an octatonic (eight-note) scale that alternates between half and whole steps. In C, it goes: C, D♭, D♭, E, F♯, G, A, B♭, C.

[1:15]
Using the diminished scale

The diminished half-whole scale adds tension over a dominant chord (e.g., C7 resolving to F major) by providing the flat 9, sharp 9, sharp 11, and 13.

[1:56]
Minor pentatonic scale explained

A five-note scale: C, E♭, F, G, B♭, C (root, minor third, fourth, fifth, dominant seventh). It's the most important pentatonic scale.

[2:34]
Using the minor pentatonic scale

Played over a C minor chord, the musician shows how to vary the pattern rather than simply running up and down.

[3:18]
Blue scale definition

The blue scale is the pentatonic scale plus a flatted fifth (flat 5). In C: C, E♭, F, F♯/G♭, G, B♭, C.

[5:07]
Secret blue scale (bonus)

Same as the blue scale but with a major third added: C, E♭, E, F, F♯, G, B♭, C. This gives a 'real blue sound' and more flexibility.

Mastering the diminished, pentatonic, and blue scales is essential for any aspiring jazz musician. Adding the secret blue scale with a major third further expands your expressive palette.

[00:00] do you know the three scales that all

[00:03] great jazz musicians

[00:07] know that's

[00:12] diminished that's

[00:17] pentatonic and that's the blue scale if

[00:20] you're not up on those three scales no

[00:22] problem I've got you covered trigger

[00:24] warning this gets a little Advanced and

[00:26] I go fast because we're hitting three

[00:28] indispensable scales in just 6 minutes

[00:30] but it's super essential if you want to

[00:32] become a great player and make sure to

[00:33] stick around to the end I've got a

[00:35] special bonus secret scale something

[00:37] that none of the theory books ever talk

[00:39] about but that all the pros use so let's

[00:42] dive in first up is the diminish scale

[00:44] what exactly is the diminish scale it's

[00:46] an octatonic or eight note scale that

[00:49] alternates between half and whole steps

[00:51] let's look at the diminished scale in

[00:53] the key of

[00:57] C half step whole step step half step

[01:01] whole step half step whole step half

[01:04] step whole step c d flat d flat E F

[01:09] sharp G A B flat C simple stuff

[01:15] diminished half hole scale okay how do

[01:17] we use it well we can add

[01:20] tension over a dominant

[01:26] chord so if we're starting on C7 and

[01:29] then then we're going to resolve to F

[01:30] major normally we might be

[01:32] [Music]

[01:34] going just over the dominant scale but

[01:37] with that diminished half

[01:42] hole it gives us the flat nine the sharp

[01:45] nine sharp 11 to

[01:48] [Music]

[01:52] 13 all those great tension points next

[01:56] we have the pentatonic scale this is of

[01:58] course a five note scale and it's worth

[02:00] noting that there's actually quite a few

[02:03] different types of pentatonic scales but

[02:05] the most important is the minor

[02:13] pentatonic so what is it we've got C E

[02:16] flat F G B flat C so we've got the root

[02:22] C the minor third the fourth the fifth

[02:27] the dominant 7eventh and back up to the

[02:29] root

[02:34] all right how do we use the minor

[02:36] pentatonic here's an example over a

[02:38] classic C minor

[02:40] [Music]

[02:57] sound now you notice I'm not just

[02:59] running up and

[03:00] [Music]

[03:02] down that doesn't really work I'm

[03:05] varying

[03:06] it I'm finding those shapes in there you

[03:10] can check a link below I did a whole

[03:12] video on how to practice this minor

[03:14] pentatonic scale to get you to that

[03:16] place our third and final essential

[03:18] scale is the blue scale now what exactly

[03:21] is the blue scale well be glad that you

[03:23] just learned the pentatonic scale

[03:25] because the blue scale is exactly the

[03:27] same with just one additional

[03:35] note okay so the

[03:38] pentatonic the

[03:40] blues that flatted fifth that's the

[03:43] additional

[03:45] note okay so we got six notes 1 2 3 4 5

[03:48] 6 back up to the root C E flat F F sharp

[03:54] or g flat flat and fifth G natural B

[03:58] flat C

[04:02] [Music]

[04:15] that's all with the blue scale and you

[04:17] see how coming out of those patterns

[04:19] those shapes that we learn from the

[04:21] pentatonic scale how you can really

[04:22] spice things

[04:23] [Music]

[04:26] up now this is not really the

[04:29] traditional way way that we use the blue

[04:30] scale it works there too if we kind of

[04:32] [Music]

[04:40] do over an actual

[04:44] [Applause]

[04:57] Blues that's the three scales that all

[04:59] the Masters know of course there's a

[05:01] bunch more but if you get these down

[05:03] you're going to be well on your way to

[05:05] being a fantastic jazz musician now

[05:07] here's a little bonus here we learned

[05:09] the

[05:10] pentatonic the blue scale what about the

[05:13] secret blue

[05:16] scale same as the blue scale but with a

[05:19] major third

[05:23] also that's how you get that real blue

[05:25] sound so you got the root minor 3D major

[05:28] 3D fourth flat and Fifth Fifth dominant

[05:34] seventh rot c e flat E F FP G B flat

[05:46] C gives you a lot of flexibility

[05:51] [Music]

[06:08] peace and

[06:19] piano someone's been using my setup
