Zach provides advice on bowings that are useful for improvisers and playing music that is less arranged. He gives a tip for thinking of the 'swing' feel as triplets not dotted 8th or sixteenth notes.

Lesson transcript:
Let's talk about the bow and how it relates to time feel. I'm assuming that if you're watching this, you've spent considerable time using your bow to create the proper sound on your instrument or to achieve a nice tone.
In more advanced discussions, we'll delve into various sounds and ways to purposely play incorrectly to create effects. For instance, you can create electronic effects on your string instrument with no electronics.
For now, let's focus on some alternate bowings that will help you improve your time feel.
Of course, we've got our basic detach? (separate bows). Many of you are probably also accustomed to:
Before we explore odd groupings (a whole other topic), I want to discuss slurring two notes, but without slurring from the first beat. We are specifically addressing 4/4 time right now. Later, we'll explore different time signatures and related concepts.
Let's get the trusty metronome going. I'm going to play eighth notes, slurring every two.
Exercise:
So right now, we're slurring 1 to 2 and 3 to 4. In terms of the eighth notes, I want you to slur like this:
It should sound like this:
"S-L-U-R!"
There's something about that which already feels a little groovier.
Now, let's say I emphasize the accents more when I change the bow. I achieve this with a little pronation in my bow hand, giving it that extra impulse.
As classical players, we're often trained to disguise the shift and the bow change. However, here, I'm actually using the bow change to add rhythm to my line.
For some of you who have experimented with jazz, you know the dreaded sound of a classical player trying to adapt to a jazzy time feel. Oftentimes, this is a result of poorly written pop scores where a swing rhythm is represented as a dotted eighth note followed by a sixteenth note.
This creates a very stilted sound, unless you're aiming for that old-time recording quality.
For those who are struggling with herky-jerky time, consider this:
If we want to get into a more technical discussion about how to approach swing, I suggest that classical players think about groove or swing more in terms of triplets rather than dotted eighths and sixteenths.
This idea stems from the fact that within every duple, there is a triple, and within every triple, there is also a duple. This concept runs through the time feel of great improvisers, regardless of style.
To enhance your swing concept, consider:
However, if that still doesn't sound right to you, don't worry; there are many resources available to explore this further.
We can practice every other note bowing. For example, consider groups of:
These variations, as seen in the Galamian bowing techniques, are highly useful for improvisation.
I encourage you to revisit some of the modes and scales we've worked on and alter your bowing techniques:
When practicing bowings, make sure not to always start with a down bow. It's beneficial to alternate and practice starting with an up bow.
As you can see, preparing for improvisation means preparing for the unexpected. Think of it like a football player doing tire exercises:
As you engage with each exercise we discuss, always think about practicing the opposite. If there's a certain direction you typically follow, try reversing it!

Heralded as "the pre-eminent improvising violinist of his generation," Zach Brock is a violinist and composer whose music draws on the traditions of jazz, classical, world and popular music. Zach received his first Grammy Award in 2017 for his work on Snarky Puppy's album Culcha Vulcha. His acclaim as a bandleader has grown through appearances at venues such as Carnegie Hall and festivals like "Tudo e Jazz" in Brazil, while his reputation as a sideman has spread through his work with legendary bassist Stanley Clarke, contemporary instrumental super-group Snarky Puppy, and jazz masters Phil Markowitz and Dave Liebman. Zach has made ten recordings as a leader or co-leader and is the first violinist to record for the venerable Dutch jazz label Criss Cross. He has also represented the U.S. Department of State as a Musical Ambassador in the Solomon Islands, performed as a featured soloist for two Sundance Festival feature film scores, and is currently an Artist In Residence at Temple University in Philadelphia. In his course you will learn to improvise on the violin straight from the source: how Zach approaches melody, rhythm and harmony, and how to start finding your own voice the way he has alongside Snarky Puppy and beyond. read more
