- Avoid translating 'jam' literally as 'варенье'. It is a fixed calque from English 'jam session' -> 'джем-сейшен' / 'джам-сешн'. Using a literal translation will not be understood.
Common Mistakes
- Using it to describe a solo practice session (requires multiple people).
- Using it for a formal, rehearsed performance.
