Common Cor Anglais Instrument Mistakes to Avoid

Some mistakes with a cor anglais are just embarrassing; others end up costing real money in repairs. Having watched plenty of players — myself included, in a couple of these cases — make the same errors, here's the honest rundown of what to avoid.

Mistake 1: Treating the Reed Like an Oboe Reed

It looks similar at a glance, but a cor anglais reed is wider and sits on a curved bocal rather than fitting directly into the instrument. Assuming oboe reed habits transfer directly — scrape, cane thickness, how you judge resistance — leads to a lot of unnecessary frustration. Treat it as its own thing from day one, not a slightly bigger oboe reed.

Mistake 2: Blaming the Instrument for Bocal Problems

A surprising number of intonation and response issues actually trace back to the bocal, not the body of the instrument itself. Because there's often no simple tuning slide to reach for, players sometimes conclude an instrument is faulty when a different bocal, or a small adjustment to reed and embouchure, would fix the issue entirely.

Mistake 3: Playing a Cold Instrument Hard, Straight Away

Wooden instruments, this one included, can crack if they're exposed to sudden temperature changes and then played forcefully before they've acclimatised. Coming in from the cold and launching straight into a loud passage is a genuinely common way people damage an otherwise well-cared-for instrument. Give it time in the room before you push it.

Mistake 4: Taking It to a Generalist Repair Shop

Not every woodwind technician works comfortably on oboe-family instruments, and the cor anglais has its own quirks around bocal fit, pad regulation and bore-specific adjustments. A generalist repairer used to flutes and clarinets can genuinely do more harm than good here. Find someone who specifically services oboes and cors anglais, even if that means travelling a bit further.

Mistake 5: Skipping the Swab

Moisture left sitting in the bore after playing is a slow, quiet way to cause long-term problems, from pad wear to changes in how the wood behaves over time. Swabbing out after every session takes seconds and is one of the cheapest habits you can build for the instrument's long-term health.

Mistake 6: Getting the Transposition Wrong

Because this is an instrument in F, a written note doesn't sound at the pitch it appears to. Players and arrangers who forget this — especially when adapting music not originally written for the instrument — end up with parts that sound a fifth away from where they're supposed to sit. Double-check transposition carefully any time you're arranging or transcribing rather than assuming it works like a non-transposing instrument.

Mistake 7: Buying on Brand Name Alone

A respected maker's name on the bell doesn't guarantee that particular instrument suits your hands, your reed setup or your playing style. Skipping a proper trial because a brand is well regarded is how people end up with a technically excellent instrument they never quite gel with. Try before you buy, every time it's genuinely possible.

Mistake 8: Rushing Repertoire Before Tone Is Solid

It's tempting to chase harder pieces early, but a shaky, thin tone doesn't magically improve just because the music gets more difficult. Spending real time on long, steady notes before moving on to demanding repertoire pays off far more than pushing ahead too soon — a mistake nearly every player makes at least once, usually out of impatience rather than a lack of ability.

The Bottom Line

Most of these mistakes cost nothing to avoid once you know they're there — a bit of patience, the right technician, and treating the reed and bocal as the specific things they are rather than oboe equivalents.
