Connotations
Identical core connotations. In technical contexts (aviation, surgery), the term is equally standard.
Frequency
Slightly higher frequency in American English in financial/legal contexts due to market size. Musical sense is equally frequent.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using 'инструмент' for abstract 'means' in all contexts; 'средство' may be better. In music, 'инструмент' is correct. The legal 'instrument' is often 'документ' or 'ценная бумага'.
Common Mistakes
- Using 'instrument' for very simple, non-specialised tools (e.g., 'a hammer is an instrument' – possible but 'tool' is more natural). Confusing 'instrumental' (adjective) with 'instrument' (noun).
