版权授予文学、音乐、戏剧或艺术作品的作者、作曲者、剧作者、出版商或独家经营出版、生产或销售的批发商的合法权利

The legal right granted to an author, a composer, a playwright, a publisher, or a distributor to exclusive publication, production, sale, or distribution of a literary, musical, dramatic, or artistic work.

我认为对加拿大整个地区的独家经销来说，年销售量三百架钢琴未免太保守了。

I think the annual sale of300 pianos for a sole distributorship in Canada is rather conservative.
