water key
C2Technical/Musical
Definition
Meaning
A small valve or lever on a brass musical instrument (e.g., trumpet, trombone) used to release accumulated saliva (condensation) from inside the tubing.
By metaphorical extension, it can refer to any small drainage tap or release mechanism for liquid, particularly in technical or engineering contexts (e.g., on a boiler or pipe). However, this use is rare and the musical sense is overwhelmingly dominant.
Linguistics
Semantic Notes
This is a highly specialized compound noun. Its meaning is entirely opaque without domain-specific knowledge of brass instruments. It is not a 'key' in the sense of something that unlocks, but a lever-operated drain.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. The term is standard in both varieties within musical contexts. British English might occasionally use the term 'spit valve' more interchangeably, though 'water key' is still prevalent.
Connotations
Neutral technical term in both regions. 'Spit valve' is considered more informal/colloquial.
Frequency
Equally frequent in both US and UK musical jargon.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'водяной ключ' which would imply a water source or a tool for turning water on/off. The correct technical term is 'отверстие для удаления слюны' (saliva removal hole) or 'спускной клапан' (drain valve).
Common Mistakes
- Using it to mean a tap/faucet (AmE) or a key that operates with water.
- Treating 'key' in its more common sense (for locks or answers).
- Confusing it with 'water valve' in a plumbing context.

FAQ
Frequently Asked Questions
Yes, they are synonyms. 'Spit valve' is a more informal, colloquial term, while 'water key' is the standard technical name.
Most modern brass instruments have at least one, typically on the main tuning slide or the lowest bend. Some smaller or historically-informed instruments may not.
The term likely originates from the lever's resemblance to a key, as it is often a small, finger-operated lever that you press (like pressing a key). The word 'valve' is also used ('spit valve').
Not for long. Failure to clear condensation will eventually cause a gurgling sound, impede airflow, and potentially damage the instrument's interior over time.
