Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'auxiliary' as 'вспомогательный' in a generic mechanical sense; it's a specific music term 'вспомогательный тон'.
- Avoid confusing with 'побочный тон', which can be broader and less precise.
Common Mistakes
- Using 'auxiliary tone' interchangeably with 'passing tone' (which steps between two different chord tones, not returning).
- Placing the auxiliary tone on a strong beat, which is stylistically incorrect in most common-practice period music.
