It's no secret that I'm a lover of jazz. But, what jazz means exactly varies person to person. The narrative of this musical genre extends back to the beginnings of the 20th Century. No wonder, then, that it bends definition.

Step away Merriam and Webster.

Nonetheless, contemporary listeners are happy to describe a band or musician as jazz. So, what the fuck does it mean?

There isn't any doubt that jazz, as in the heyday of jazz, influenced everybody today. Billie, Duke, Ella, Coltrane and even Oscar (my kid's namesake) are just some of the notable names that we associate with the jazz sound. And, pity any musician who doesn't name at least one of these as an influence.

7th chords. Mmmm, mmmm, juicy harmony. Not to mention the melodic freedom that comes with those juicy harmonies.

Even if you have no idea what the 7th is, or how we get there, or what kind of building our notes are building, you know 7th chords when you hear them. Something sounds, "bluesey"? Well, you just heard some dominant 7th chords and it was really juicy to your ears. Mmmm, mmmmm. Yummy!

Lately I've been obsessed with musicians who've obviously studied their ii-V-I progressions (holla jazz!). Yet, so much more is going on.

Both Esperanza Spalding and Xenia Rubinos have ties to Berklee College of Music (known for it's jazz instruction) and Hiatus Kaiyote hails upon the jazz from all the way over in Australia. But complex chord progressions and odd time signatures are only the beginning. Synthesizers, compelling storylines and atmospheric vocal lines define these artists equally to their training.

I have a theory about songwriters these days: they've had exposure to the great American song form - jazz - and they've had ample opportunities to study it in music lessons - as compared to strictly Classical. And they've made it uniquely their own.

Here are some of my favorite jams of late.

Esperanza Spalding released an album earlier this year, "Emily's D+Evolution". It's a great album. I highly recommend you buy the whole thing. It's very prog and very conceptual, coming from a strong jazz background. I like this track:

Xenia Rubinos released her sophomore album a few months ago. Out of Brooklyn, she brings a fresh take on the region's legendary hip hop. She studied jazz singing at Berklee and her breathy, but large, range is used to accentuate a broad harmonic chord progression. Note, the 7th chords! I can't stop jamming the entire album - it's so stellar! - and it demonstrates the wonder of jazz song form with a great deal of 21st Century style thrown in. The following track opens with a haunting vocal line that only a jazz singer could deliver with authenticity:

And so I must talk about Hiatus Kaiyote (pronounced "hiatus coyote") from Australia. Jazz, most definitely, with a punk edge and a romantic sensibility. It's awkward time signatures and strange meandering through thick chords is inviting rather than alienating. Seriously, this has been my go-to on the bus to work. As you can imagine, I arrive at work in a blissed out state. Take this tune (and buy the whole damn album, please):

Love your 7th chords. Mwah, mwah. Juicy! It's the language of now.

[Purchasing albums, from digital platforms or your local record store, help support musicians who sacrifice pretty much everything for the sake of creating life-changing sounds.]
