Now, we are going to discuss the use of pentatonics in improvisation. To that end, we will use a Sus Blues in F. As you might remember from lecture two, pentatonics are five note scales, and they're diverse intervallic structure, renders them particularly effective in improvisation. On the screen, you can see two pentatonic collections on F. One suspended, and one minor. We will use these scales to improvise in the blues, Sus Blues. So here is F suspended pentatonic. [MUSIC] And here is your minor pentatonic. [MUSIC] When you compare the two, you can see that there are lots of notes that are held in common, in fact, one note different between these two collections. The suspended has the [SOUND] G, and the minor pentatonic [SOUND] has the A flat instead of, and all four notes are basically the same. So, because of the very diverse intervallic content, these and other pentatonic collections are very useful for practicing. And you can practice these in the same way you would practice your skills, skipping certain notes but instead of creating patterns, [MUSIC] You can create something far more interesting by skipping one note, [MUSIC] You can create far more interesting melodic lines. All right, in addition to these scales, suspended and minor, you can experiment with these pentatonics by slightly modifying their [INAUDIBLE] structure, and you can come up with different pentatonic collections that you can use with the same chords. So, on the screen, you can see the suspended pentatonic along with two scalar variations. Okay, so here's your suspended pentatonic. [MUSIC] And, here's one variation. Instead of C, [MUSIC] And this is your second variation. [MUSIC] So these three scales share certain notes in common. All of them has the fourth and the flat seven. These notes are truly defined the suspended qualities. But other notes are kind of this place and you can use them at your discretion. As long as you have five notes within an octave, you're creating a pentatonic collection. And again, these variations are useful should you choose to arpeggiate, or using different intervallic patterns while you improvise. And the same thing goes for the minor pentatonic. Here's your traditional minor pentatonic. [MUSIC] And here's one variation. [MUSIC] So in other words, you are replacing the fifth of that scale with the upper diatonic neighbor to create a more pungent-sounding pentatonic collection that you can use in addition to the regular minor pentatonic. Okay, so here is our Sus Blues. Remember? [MUSIC] F sus for four measures. [SOUND] B flat sus. [SOUND] F sus. [SOUND] And the last four bars. [SOUND] B flat sus. [SOUND] A flat sus. [SOUND] All right, so now, on the screen, you can see the distribution of a specific pentatonic collections. So with F sus. [MUSIC] B flat, [MUSIC] F sus, [MUSIC] B flat sus, [MUSIC] A flat sus, [MUSIC] Later on, Luke Norris is going to show us how to improvise with these scales but, the thing that I already mentioned, practicing these skills using different intervallic patterns or different scalar configurations, skipping certain notes, and trying to come up with a convinsive melody that uses only these five notes. If you can create, improvise a convincing so. Now, remember, we've also discussed different variance of these pentatonics. So, instead of traditional pentatonics collection, [SOUND], we can use different ones [MUSIC]. So we can start on a Sus, then with B flat Sus chord, we can use minor pentatonic, [MUSIC] Once we start improvising on a kind of suspended harmonies, and suspended harmonies are kind of androgynous to begin with. They are neither minor nor major. So we can experiment with different pentatonics. And since pentatonics are devoid of any strong tonal associations, you can kind of mix and match. Remember, when we discuss suspended pentatonics and minor pentatonics, there's only one node different between the two. And in fact the node flat three, rend is the underlying harmony with that kind of blue note characteristics, right? [MUSIC] And the last four bars, B flat sus, and then A flat minor. [MUSIC] So again, to make a long story short, you can substitute with Sus chords, you can use minor pentatonics and suspended pentatonics with different variants. And you can generate melodies based on these pentatonic collections.
