Common Pitfalls
Translation Traps (for Russian speakers)
- Не следует переводить как "октахорд" без пояснения или контекста, так как слово полностью заимствованное и непонятно русскоязычному читателю. Лучше описательный перевод: "восьмиструнный инструмент" или "восьминотная система".
- Не путать с "октавой" (octave), которая является интервалом, а не инструментом или системой из восьми нот в последовательности.
