Cymbal and symbol are homophones. It tends to be symbol that is used when cymbal would be appropriate rather than the other way round; I suspect that is because symbol is simply more familiar. I also find cymbal is sometimes misspelt as cymbol (I haven’t been able to find any sources that accept cymbol as a legitimate alternative spelling, but I would be interested to hear from anyone who has such a source).
- a slightly concave, round brass plate which is struck against another or with a stick to produce a sound
Symbol
- a mark, shape, sign, figure or character used as a conventional representation of an object, quantity, function, process or organisation
- a thing that stands for or represents something else
My tip: cymbals are used when producing music.








There is a widespread tendency to use cf. to mean ‘see’ or ‘see also’. This usage is usually frowned upon (see New Hart’s, The Chicago Manual of Style, and the Penguin Guide to Punctuation).
