Confident entrances

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!

I felt a lot of stress and pressure during my years in college and graduate school, about jazz and Learning Tunes. Nobody who is anybody uses a fakebook! You have to Learn the Tunes! Do you know All the Tunes? Why don’t you know More Tunes?

My teachers told me I would never make it as a jazz player unless I knew hundreds of tunes by heart. Melodies, chord progressions, and “standard” intros and outros. And since I’m a reed player, I would need to know them in at least a couple of keys. I tried, but I found it pretty daunting. My teachers seemed to think that meant I was doing it wrong, in some way they could not specify.

And besides, fakebooks are bad! They have mistakes, unlike other kinds of sheet music! Plus, the fakebook version of that tune might not be the true and authentic secret original version, but merely a common and tasteful reworking! And if you’re looking at a fakebook, you’re trapped within the confines of the printed page, literally unable to play anything creative!

My university degrees are in “classical” performance, and in multiple instruments, so jazz has never been my sole concentration. If I had done more focused and advanced study of jazz, I suppose I would have had to Learn All the Tunes, or flunk out and fail to make it in the business.

But it was never my goal to be the next big name in jazz. I love to play jazz music, but I’m quite content to do my best impressions of my favorite players, take modest solos, and yes, use a fakebook. Of the musicians in the world who play jazz at some level, very few are recording on Blue Note or headlining at the Village Vanguard.

For hobbyist or part-time jazz players, a fakebook can be very useful. Using a fakebook on a gig means I can just play the tunes the group wants to play, rather than slinking away in shame at my failure to Know them All. It means we’re all on the same page, so to speak, about keys, chord changes, forms, intros, and endings. The practicality of low stress and high versatility wins out over the ideal of never looking at a music stand. I can Learn Tunes by playing them frequently in a relaxed atmosphere. And if I forget a chord or a melody note, I can fall back on my musical skill of reading notation.

Is learning tunes by heart preferable? Probably, ideally. If you’re in a jazz studies degree program, or trying to break into the top-level jazz scene in a major market, you may indeed find it necessary to memorize a whole lot of tunes as quickly as you can. But for the rest of us, there’s no shame in using a fakebook.
