Slurring on the trombone is hard. Unlike trumpets, where valves allow instant note changes, trombonists need to master slide control, tonguing articulation, using alternative positions, and steady air support to achieve slur articulations. Here are the key skills to focus on as well as the top method book to practice trombone slurs.
How to Slur on the Trombone
Slurring on the trombone is trickier than on other brass instruments because it requires quick slide movements to avoid glissando. By using a soft "du" tongue articulation and shifting to alternative slide positions, trombonists can create smooth, connected slurs, especially in the higher registers, with a lip slur.
Why Slurring on Trombone Is More Challenging
Slurring on the trombone is harder than on other brass instruments due to the slide. Unlike trumpets, where valves allow instant note changes for smooth slurs, trombonists must move the slide quickly between positions. Slow or awkward movements can cause unwanted glissando, so trombonists must focus on rapid slide transitions while maintaining a steady air stream.
The Role of Tonguing in Slurring
Slide movement is key for smooth slurs, but trombonists also use softer tongue articulation to connect notes without fully tonguing each one. The “tu” tonguing for single note attacks is too harsh for slurs, so a lighter “du” articulation is used. This creates a smoother connection between notes without breaking the flow, while quick slide movements prevent abrupt glissando. The goal is to keep the articulation light and fluid, allowing for seamless slurs. This simple exercise below is a great place to start.
Practice Lip Slurs (No Tongue)
Adding lip slurs to your practice routine is essential for learning to shift between pitches without relying on the slide or tongue. Once mastered, this feeling of the lips "popping" into place when slurring to a new note can be applied to slide transitions, helping you achieve smoother, more fluid slurs on the trombone.

Once lip slurs are mastered move to a basic trombone slur exercise that uses the slide. Aim to move the slide quickly and use a gentle "du" tongue.
Slurring with Alternative Positions
Using alternative slide positions is an effective technique for achieving smooth slurs on the trombone. By playing notes in different positions, you can control transitions better and avoid the glissando effect caused by slow slide movements. For example, when slurring from first to third position, moving to second or even fourth position can help create a smoother slur. This technique is particularly useful in higher registers, where shorter slide positions make quicker transitions easier to manage.
Best Trombone Method Book For Slur Exercises
One of the most famous brass method books, Arban's method includes a dedicated section on slurs. The book is widely used for its clear exercises designed to improve flexibility, articulation, and slurring, making it a staple for trombone players at all levels.
Maintaining a Steady Air Stream
To execute smooth slurs, maintaining a steady and consistent air stream is key. The air stream needs to remain steady while quickly adjusting the slide between positions. Rapid slide movements without a consistent airflow will result in uneven slurs and potential breaks in sound. Keeping the air stream flowing smoothly as you change slide positions is essential for making the transition as seamless as possible.
