Performance and Instrumental/Vocal Technique
This domain tests posture, breathing, tone, intonation, articulation, practice method and ensemble awareness. Examiners reward control and consistency, not just speed or volume. A secure slow performance scores better than a rushed, inaccurate one.
Technique
Set posture first: feet grounded, shoulders free, instrument aligned. Singers support from the diaphragm and avoid raising the shoulders. Wind players keep a stable embouchure and steady airflow. String players use relaxed bow weight and consistent contact point. Articulation must be clear and matched to style.
Intonation and tone
Tune to a reliable reference. Wind players adjust with air and embouchure, not only the tuning slide. String players use open strings and double stops. For tone, keep airflow steady and listen for an even sound across the range. In ensemble, watch the conductor, listen across the group and match articulation and vowels.
Worked example
A clarinettist plays a sustained note that rises in pitch as the phrase gets louder. Diagnosis: insufficient breath support and excess jaw pressure. Fix: keep the embouchure stable, use faster air rather than biting, and practise long tones with a tuner. If the low register is flat, check instrument warmth and support before moving the barrel.
Traps
Do not confuse volume with support. Do not practise mistakes at speed. In ensemble playing, do not follow only your own part; balance and intonation are marked. Do not stop at every error in a performance; keep the pulse going.
