Developing Low Notes on Trombone & Brass: Techniques and Tips

11th June 2025

ft Christopher Bill

For many brass players, hitting those booming low notes, the low register presents a set of unique challenges: breath control, embouchure flexibility, and tone consistency, to name a few. Luckily, with the right techniques and mindset, you can unlock the depth and power of the low end. We spoke with Christopher Bill, a trailblazing trombonist known for his virtuosic YouTube performances and practical advice, and have put together a few techniques and tips to support you in developing low notes on trombone and brass.

1. Start with the Fundamentals: Air and Embouchure

Low notes require more air, not just lower lip tension. Think slow, steady, and warm air – imagine fogging up a mirror across the room.

  • Tip: Try breathing exercises off the horn. Practice full, relaxed breaths through your mouth, and exhale as if you’re blowing warm air on cold glass.
  • Embouchure: Loosen the lips slightly, especially the corners, but keep control. Avoid clamping down or over-tightening the mouth. Remember, don’t puff out those cheeks! Keep the corners of your mouth low and relaxed.
  • Exercise: Play long tones descending from middle Bb down chromatically to pedal Bb. Use a tuner and a drone to keep your focus on intonation.

2. Use Your Slide (or Valves) Wisely

On trombone, slide accuracy is even more crucial in the lower register. Intonation gets slippery down there!

  • Practice moving smoothly between partials. Low notes are often missed because players are not locking into the correct harmonic series.
  • Tip: Use a visual tuner app while playing slow lip slurs down to lower positions. Watch how your pitch behaves – adjust with slide and air.

3. Develop the Pedal Range Slowly

Pedal tones are a powerful tool for developing flexibility and resonance. Christopher Bill, for example, uses them in warm-ups to open up the chops and train airflow.

  • Don’t force pedal tones – ease into them.
  • Use buzzing to help isolate the mechanics and focus on embouchure and airflow.

Exercise: Play 5-note descending lip slurs (e.g., Bb–F–D–Bb–pedal Bb) slowly, using lots of air and minimal pressure.

4. Play with Resonance, Not Just Volume

It’s tempting to ‘blast’ low notes, but this often leads to an unfocused sound. Instead, aim for resonance – a focused, full tone. It’s easy for volume to mask the flaws of playing, try playing softer but still supported and focus on control.

  • Practice soft low notes to develop control.
  • Use a practice mute to isolate your tone and listen closely.

5. Incorporate Musical Practice

Take a leaf out of Christopher’s book and use real music to refine your low register:

  • Transcribe and play bass lines (funk, pop, jazz).
  • Play long, lyrical etudes an octave lower.
  • Record yourself and listen back critically.

Exercise: Arrange or play a bass line from one of your favourite songs and focus entirely on tone and timing.

Conclusion

Mastering low notes is a journey – but with consistent practice, focused technique, and a bit of inspiration from pros like Christopher Bill, you’ll be hitting those fundamentals and pedals with confidence.
