## When to use it

Use when an explanation misses its audience’s knowledge or interests.

It can insult the listener; use cautiously, or to criticize your own communication.

## Behind the words

A traditional story describes music played to an ox that does not respond. The image draws attention to the gap between a message and its audience.

The image exposes a mismatch between a performance and the audience's ability to understand it. In use, it may criticize an unresponsive listener or the speaker's failure to communicate appropriately. It can sound insulting because it compares the audience to cattle. In a professional setting, describing the communication problem directly is often kinder than applying the idiom to a colleague.

tā duì bù dǒng yīn yuè de rén tǎo lùn fù zá de hé shēng ， yǒu diǎn duì niú tán qín 。

Discussing complex harmony with someone who knows no music is rather like playing to an uncomprehending audience.

After explaining technical details at length, I felt I had chosen the wrong audience when the client only asked about price.

你只顾用专业术语，不考虑听众，难怪像在对牛弹琴。

### Traditional Chinese

你只顧用專業術語，不考慮聽眾，難怪像在對牛彈琴。

nǐ zhǐ gù yòng zhuān yè shù yǔ ， bù kǎo lǜ tīng zhòng ， nán guài xiàng zài duì niú tán qín 。

If you use only technical jargon without considering your listeners, it is no surprise they cannot appreciate the message.
