An exam instrument and a performance instrument are judged differently. At the exam stage students repeat large amounts of basic technique daily, so what matters is not a distinctive voice but three things: stable tuning, moderate action, and clear feedback on mistakes. Meet those three and the difference between levels comes down mostly to budget and how long the instrument will serve.
Levels 1–3: stability above all. Hand position and a sense of pitch are still forming, so an instrument with uneven string height or drifting pitch is the worst choice. Look for a solid structure, standard string layout and moderate action. Appearance and tonal character are worth little here — do not overspend to "buy once". A stable beginner instrument will carry a student well into the intermediate stage.
Levels 4–7: the transition in action and intonation. Intermediate repertoire introduces more demanding presses, slides and dynamic changes, and the instrument must reflect them honestly. On a play-test, notice whether presses take too much force, whether slides run smoothly, and whether dynamics respond under the fingers. Avoid changing instruments often at this stage: the adaptation cost can cancel out any tonal gain.
Levels 8–10: dynamic headroom and tonal direction. Advanced repertoire contains long passages of contrasting dynamics and fast technique, so the instrument needs headroom — loud without cracking, soft without thinning. Only at this point does tonal direction (brighter or denser) deserve consideration. Bring your own exam pieces and play them yourself rather than listening to someone else.
Play-test checklist: 1) run scales from bass to treble and listen for gaps in intonation; 2) press several common notes and feel whether the force is even; 3) play a fast passage and listen for mushiness; 4) check that the bridges sit firmly and do not slip; 5) ask about tuning drift and after-sales. If all five pass, the instrument is good enough.
When to change: the signal is when the current instrument starts limiting progress — a press that is always slightly off, a fast passage that sounds muddy. Someone else buying a more expensive instrument is not a reason. Studios buying in batch can see our training-institution programme for tiered configuration that saves budget.
If you are unsure which tier fits the student's current stage, tell us the level, years of study and budget and we will suggest the matching tier and price range.
