University/conservatory degree programs in woodwind doubling, part II: jazz

The most important rhythmic concept in jazz is swing, an intentional unevenness of note lengths. In jazz swing, downbeat notes (and rests) are long, and upbeats are shorter and later. This phenomenon isn’t represented well by classical musical notation, but sometimes it is approximated like this:

Or like this:

The examples assign the downbeat notes a length exactly 2 times that of the upbeat notes—the triplet quarter note is twice as long as the triplet eighth, or, in other words, the swing ratio is 2:1.

The debate over swing ratios

The triplet method of explaining swing rhythm is unpopular with many jazz musicians and educators, who insist that a triplet-like 2:1 ratio is incorrect. Most of them, if pressed, are unable to provide a better ratio or formula. Instead they insist on the importance of listening to jazz to aurally absorb the “correct” ratio (or system of ratios, perhaps varying with tempo), or propose that swing can only properly be “felt” rather than explained.

There are a number of things that these musicians and educators are correct about: a triplety ratio isn’t necessarily correct, and listening is important.

What these otherwise fine folks sometimes get wrong is the idea that swing can’t be measured or analyzed. In fact, it has been extensively measured and analyzed by a number of scholars, and some useful generalizations can be made. (If you want to dig into the research, an excellent place to start is the article “Preferred swing ratio in jazz as a function of tempo” by Anders Friberg and Andreas Sundström, published in TMH-QPSR, volume 38, no. 4, 1997.)

Some helpful swing generalizations

• In general, yes, a swing ratio of 2:1, triplet-style, works fine for many situations, particularly at moderate tempos.
• It’s fairly common for swing ratios to increase (something like 2.5:1 or even higher) at slower tempos. A higher ratio could be described as “swinging harder.”
• It’s also common for swing ratios to get lower at faster tempos (like 1.5:1). This could be described as “not swinging as hard” or maybe playing “straighter.”
• However, jazz performers’ ratios vary, depending on factors that are perhaps best summarized as “personal taste.” And, yes, the best way to develop this informed taste is by listening to and internalizing a lot of great jazz.

It might be helpful for classically-trained musicians to consider how they interpret something like a grace note—its individual placement, length, emphasis, etc. depend on many factors, and a “swung” eighth note’s interpretation is similarly complex.

Happy swinging!

Recently I asked some questions on social media related to (self-identified) non-jazz musicians playing on jazz or jazz-adjacent gigs. This kind of thing might happen, for example, at a symphony pops concert, or a big band gig in a smaller market.

A number of concerns were raised about this, but two stood out.

• Self-described non-jazz players overwhelmingly expressed misgivings about having to improvise in these situations.
• For jazz players, asked about having to play a gig with non-jazz musicians, none of them expressed concern about the non-jazz players’ improvisational ability. They were overwhelmingly concerned with style (mentioning specifics like swing, articulation, and inflection).

I think for a non-jazz player, being asked to improvise is understandably frightening. But I’m hard-pressed to think of a situation like this where improvisation would be strictly required. For example, if your local pick-up big band has some jazz players and some non-jazz players, it’s a simple enough matter to pass the improvised solos off to the jazz players. (And there are plenty of big band charts with written-out solos.) If I’m hiring for the gig, I’d certainly rather rearrange the solos than put somebody in a situation that will be to their embarrassment and mine.

But everyone on the gig needs to be prepared to do good section playing. I’ve been in the frustrating situation of trying to lead a section (from the lead chair or from the director’s stand) with players who aren’t tuned into the conventions and nuances of swing, articulation, and inflection. Often these things aren’t specifically notated, the way they would be in orchestral parts, or the notations aren’t intuitive.

(A case in point: a curved marking like ⌣ over a note, which I hear classical musicians interpret by playing the note at pitch, then bringing it down, then back up. I understand why they think it means that, but it’s an un-jazz-like sound—it should almost always be interpreted as a scoop up to pitch.)

My takeaway: if you don’t consider yourself a jazz musician, and aren’t planning to really become one but want to play some jazz-oriented music on the occasional gig, study jazz style.
