Dominant 7th Scale Choices with Jens Larsen

This is a lesson demonstrating a few of the common scale choices over dominant chords and talking a bit about what I think characterizes them and how I approach improvising with them.

I've had a few questions about what options there were for scales and sounds on dominant 7th chords so I decided to make a lesson demonstrating a few of the common ones and talking a bit about what I think characterizes them and how I approach improvising with them.

I set out to just make a few short examples, but in the end I talk a bit about how I use the scales and about the lines so the video became a bit long. In the end I thought the information was useful so I left it in there.

As I mention in the video I often uses the chords when learning scales so if I want to learn to improvise with a certain scale at some point in a progression or song then I find a chord that really sounds like that scale and play that in the context of the song to hear how it sounds.

Mixolydian or F7 from Bbmajor

In this example I am "just" using the Bb Major scale. It seems logical as a starting point and as a reference. I did try to make a melody on the F7 that was at least not cliché. I do that by using Drop2 or Open voiced triads, something that might be a subject for a later lesson too as they are a very good way to incorporate larger intervals in lines without sounding too fragmented.

Mixolydian b9b13, F7 from Bb Harmonic Minor

In this example we borrowed the dominant of Bb minor in the cadence. It works well with a lot of different chord types to borrow an equivalent from the minor scale. Mixolydian b9b13 is also more or less the first choice for a scale on an F7 that resolves to a minor chord, so for that it is important to know it. I chose the F7(b9) chord as an example because it has a 5th and a b9 which in context gives paints the F7 from Bb harmonic minor sound (to me anyway).  Part of the line on the F7 is based on the A diminished arpeggio which is also diatonic to Bb Harm min. and is a good arpeggio to check out when using that scale.

The Altered Scale

Playing F# melodic minor is on an F7 chord is mostly described as the F7 altered scale. The melodic minor scale has a strong augmented sound in it and the scale also sounds a bit like the whole tone scale as I demonstrate in the video. Making lines on F7 altered I find it a good starting point to use the fact that F# melodic minor also contains the B7 which is the tri-tone substitute of F7. As an example I use the  B7 and F#m triad arpeggios in the line. If it is difficult to hear the F7 altered then it can be good to really just play/think B7#11 and resolve that to Bbmaj7 to get used to the sound.

The Diminished scale

The diminished scale is another good scale to apply to dominants. It is to me characterized by the fact that it has alterations on the 9 (which to me sounds minor), but has a natural 13 (which sounds like major), which is why it has some things sounding like minor and some like major. This mix of minor and major extensions makes it a bit difficult to use in some situations.

One important aspect of the diminished scale is that it is symmetrical, so everything can be transposed in minor 3rds and still be in the same scale. This is handy in terms of guitar technique because it is easy to move a phrase like that on the guitar, but often the phrases you get when you make melodies like that are very predictable and (to me) not very beautiful.

The way I mostly approach making melodies with the diminished scale is to mix up the triads that it contains, for the F7(13b9) chord there are 4 major triads contained in the scale: F Ab B and D, so I mix those up to make lines, of course there are many other ways to make lines, this just happens to be what I mostly do (right now anyway).

The Whole tone scale

The Whole tone scale was until now a bit of a special effects scale to me. But as has happened before, when I make a lesson on something I get to rediscover things. In a way the Whole tone scale is the opposite of the diminished scale because it has a natural 9 and altered 5th or 13. Since it is a scale consisting only of Whole steps there are not that many options for chords, everything is augmented triads and dominants, so that is what you have to work with when making lines.

As I also mention in the video I sometimes use the whole tone scale as an effect in situations where the chord contains an augmented triad, in a way letting the triad decide what Whole tone scale to use even if that does not fit with the rest of the chord. As an example a AmMaj7 where the chord contains the Triad C E G# so you could play C D E F# G# Bb on it, a similar trick could Work on a D7(9#11)).

    I even don't know who is the jazz musician in this world, so i don't know where to start. I think the sound of jazz is hard to understand. I sometimes don't know when it tell us about sadness or happiness. Maybe i have no good interpretation in this kind of music.

    Hm.. well try to check out some of the classics: Charlie Parker, Miles Davis: Kind of Blue, John Coltrane: Giant Steps. And some Wes Montgommery and Joe Pass. YouTube and wikipedia should get you quite far..

    Every chord notated as "Cm7" are actually Cminor9's. The F7 in the first section is actually a Fdominant9. "F9(b9)"? lol ok. Extensions are outside the parenthesis. Alterations are inside parenthesis. C7(13 b9) = C13(b9). Incorrect information leads to incorrect usage.

    I think deep down... What you're really saying is "My dad didn't hug me enough." Don't take it out on Jens. He's a wonderful man.

    Yea dude, relax. I usually love ripping apart lessons but all the things you stated are sort of pointless. Function in this case is more important than which extensions are being used. Anyone who plays jazz generally adds extensions of their own desire anyway. Plus you could have at least been constructive in a non douchey manner.

    It was probably just accidental on his part as far as the F9(b9) is notated in the lead sheet. He accounts for it later F9(#5), so it's not like he did it on purpose. I thought his lead sheet wasn't confusing to interpret, and if you were simply to read the notes the lead sheet wouldn't even matter.
