Lesson transcript:
A lot of stuff that I've been playing in this course so far has been using a lot of unorthodox bowings for some of you out there. You might notice that the way I'm playing certain melodies does not sound like a straight classical interpretation, no straight eighth notes.
We've talked a little bit about melody and harmony. Now, I want to discuss rhythm in a couple of different ways. Rhythm can manifest as:
These rhythmic ideas can serve as a springboard for all kinds of improvisatory concepts.
Before diving deeper into rhythm, I want to emphasize the concept of time feel on the violin. This can also be referred to as "groove."
If you're a classical player who has never experimented with other types of music, approaching this idea might feel daunting. You likely have a strong technical facility on your instrument, but you may find that even when you play the right notes, something doesn't sound quite right when you try to play along with a recording.
Folk players, such as:
These musicians already have a distinctly different kind of time feel compared to classical music. For example:
Both genres are "groovy," but they are unique in their expression.
From a jazz perspective, I find the term "pocket" incredibly useful. It represents a comfortable approach to time feel, applicable whether you're playing ripping Celtic fiddle or grooving to a D'Angelo record.
For many classical players, the approach to time and rhythm is often rigid:
This perspective treats rhythm as a vertical mark, locking into a grid. While this is "correct," it can also be very challenging to play in this way, requiring countless hours of metronome practice.
Here's your first assignment regarding time feel:
Visualize Time: Instead of thinking of time as a linear progression, consider it like a tennis ball or a watch.
Using the watch analogy:
12:00: Perfectly on the beat
11:00: A little ahead of the beat
1:00: A little behind the beat
If you're an orchestra player working on excerpts, I challenge you to set your watch:
As I visualize the watch face, I aim to place notes slightly ahead or behind the suggested beat.
Let's return to our trusty G major scale.
Attempt to play the G major scale:
For instance: Da da, da da, da.
You might find it roughly executed, but that's not the main point. Now try shortening the distance by incorporating a tiny rest.
From my studies with jazz players, I've learned the importance of "laying back." Many string players tend to play on top of the beat. As an advanced improviser:
This control can broaden your horizons as an improviser:
For your assignment:
Record yourself while doing this! For many of you, this will be new territory. You might be astonished by the transformation in your sound when you approach it deliberately, patiently, and accurately.

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
