无论你习惯在哪儿听歌,你应该能注意到流行歌曲通常长3分钟左右。Vox公司解释道,这一惯例源自20世纪早期,当时虫胶制作的黑胶唱片(粗纹唱片)刚刚在市场上出现。这些唱片的转速各有不同,但是每分钟78圈的转速很快便成了业内标准。最流行的唱片大小是10英寸(25.4厘米)和12英寸(30.48厘米),前者每一面可以播放3分钟音乐,后者每一面可以播放4—5分钟音乐。为了让电台播放他们的音乐,让人们购买他们的唱片,音乐人基本上都会遵从这些时间限制。
No matter where you usually hear today's top hits,you've probably noticed that they tend to be around three minutes long.As Vox explains,the custom dates back to the early 20th century,when shellac records first appeared in the market.The rates at which these records spun varied,but 78 revolutions per minute(RPM)quickly became the norm.
