Mark Phillips composed T. rex for tenor trombone and electronic media as a striking 20th-century showcase that blends acoustic brass virtuosity with pre-recorded audio. If you're tackling this piece for a recital, jury, or professional performance, mastering the intricate interplay between live slide technique and fixed electronic playback requires careful preparation.
The composition is structured into four connected movements that feature sharp contrasts in dynamics, tempos, and rhythmic feels. Because the electronic accompaniment dictates a rigid time framework, you can't rely on traditional rubato or flexible rubato phrasing without drifting out of sync with the track. This guide covers movement structures, technical hurdles, rehearsal strategies, and equipment setups to help you achieve a polished performance.
Structure and Movement Breakdown
Understanding the architectural flow of T. rex helps you anticipate shifts in energy between the trombone and the electronic media.
- Movement I: Sets an energetic tone with aggressive rhythms and prominent dynamic contrasts. You'll need an aggressive articulation style to match the punchy nature of the electronic sounds.
- Movement II: Explores lyrical textures alongside sustained electronic pads. Tone control and intonation alignment are crucial here to blend with the synthetic pitches.
- Movement III: Features rapid meter changes and angular phrasing. Maintaining a steady internal pulse is essential to prevent rushing during complex syncopated figures.
- Movement IV: Drives toward the finale with explosive dynamics and rapid-fire slide movements, testing both endurance and agility.
Technical Demands for Trombone
Balancing your volume against a recorded electronic track requires careful dynamic control. You can't simply blast through loud passages if the accompaniment is already dense, and conversely, soft passages require focused core support so the sound carries over synthetic textures.
Slide Technique and Articulation
The piece demands quick, accurate position placement. Practice your intervals slowly with a metronome before attempting performance tempo. Staccato passages must be crisp, utilizing a clean tongue stroke (tah or dah depending on the desired attack) rather than a harsh chest punch.
Intonation and Electronic Blending
Acoustic trombone pitch tends to fluctuate based on register and dynamic intensity. When playing alongside fixed audio, small pitch deviations become immediately apparent. Use a drone or tuner during early practice sessions to lock in your partials, especially when matching sustained electronic pitches.
Setting Up Your Audio and Rehearsal Environment
Rehearsing with tape or digital audio tracks presents logistical challenges that differ from playing with a live pianist.
- Speaker Placement: Position monitor speakers so you can hear the electronic playback clearly without drowning out your own acoustic feedback on stage. Avoid placing speakers directly behind your bell, which can cause phase cancellation or muddy your perception of balance.
- Click Tracks and Cues: Determine whether your version of the audio includes an audible click or if you must cue yourself off the initial sound cues. If no click is present, memorize the exact cue points in the electronic track that correspond to your entrance bars.
- Latency Management: If you are routing audio through digital interfaces or mixing boards in a large hall, check for any playback delay to ensure your live articulation hits the exact millisecond required by the score.
Common Mistakes to Avoid
Performers working on electro-acoustic repertoire often fall into specific traps that hinder their execution.
- Relying on Room Acoustics: Because electronic media maintains a fixed volume, you can't rely on a resonant hall to rescue poor projection in soft sections. Balance must be rehearsed with external listeners.
- Ignoring Rhythmic Precision: Rubato is tempting during expressive lyrical lines, but the electronic track will not wait for you. Precision trumps emotional stretching.
- Neglecting Endurance: The rapid shifts between heavy articulation and high-register work can exhaust embouchures quickly. Build stamina progressively during your preparation weeks.

Frequently Asked Questions
Where can I find the official audio tracks for Phillips T. rex?
Audio files are typically provided via direct download or digital access codes included with the Warwick Music publication or publisher-designated online platforms.
Is T. rex suitable for undergraduate recitals?
Yes, it is a popular choice for advanced undergraduate and graduate trombone recitals, offering a strong contemporary contrast to standard baroque or romantic repertoire.
What equipment do I need for the electronic playback?
You will need a reliable laptop or media player, a clean stereo DI box or audio interface, and powered monitor speakers capable of projecting crisp high frequencies and low-end punch without distortion.
How should I handle balance if the hall is too reverberant?
Work with a sound technician to adjust the high-end EQ on the playback system, cutting excessive mud frequencies so your tenor trombone overtones cut through the acoustic space.
