Lesson transcript:
Everything that we're going to do from a technical standpoint with our string instrument will deal with the three areas that make up music:
I won't get into aspects like vibe and atmosphere, as that can all be part of those three fundamental areas.
Let's talk about scales. We will be playing scales in ways that you may not have practiced before. It's important to think about the direction and the container of the scale you're playing on your instrument while practicing.
Vertical Playing: For me, if I play a scale on one string, I call that completely vertical.
Horizontal Playing: Playing in position, whether I'm in first, second, third, etc., refers to horizontal playing.
When you combine these two approaches, that's essentially what you are doing. For example, if you're playing your three-octave scales and arpeggios, etc., this combination is crucial.
Additionally, there's another useful way of playing scales: focusing on modes. This is a great way to open up your creative spirit and explore what you're already playing on your instrument.
On the violin and viola, we are fortunate to have the ability to contain one octave across two strings. For cello players, I know it gets a bit more complicated. And bass players, well, you're on your own!
When thinking about scales within the one-octave container:
Of course, this could also be an arpeggio:
We will discuss seventh chords, which are extremely useful for improvisation across all styles when talking about harmony.
After mapping out your arpeggios, if you're playing in the key of E flat, for instance, adding the D natural, the seventh tone, will be key.
I should also mention that, while discussing arpeggios, I will refer to them as voicings. On instruments like the piano or guitar, you can play all of those sounds simultaneously. We can also play those voicings in a more linear way.
You want to first focus on the most basic forms of these pieces of harmonic information. You will come back to this foundational knowledge regularly.
Starting to think about harmony in this way will help you avoid getting stuck. Skipping the basics and jumping straight to more complex voicings, like a C7, can leave you feeling lost if you're unaware of the underlying structures.
Here's a fun scale exercise you can try:
Pick one particular fingering and practice moving that around the instrument.
Next, try playing a G major scale, starting on the open G.
Move that up to the next pair of strings (you'll get a D major scale).
Then, move it up to the next set of strings, up a fifth.
Let's also talk about making variations or creating a little melody within that frame. Play a scale, then challenge yourself to create a melody assignment using the notes you have right there.
That's the first thing I want you to do before we transition into more advanced techniques.

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
