sweeping melody here in romantic music,

有着悠长而广阔的旋律
a long, sweeping melody that is rather asymmetrical in shape.

悠长而广阔的旋律有着些许不对称的结构
Instead of having neat units of two plus two plus two,

替代了之前的二加二加二的规整的结构
it could go on over bars or maybe it'll be a seven-bar

旋律会贯穿很多小节
phrase, something like that.

有时会有长达七个小节的乐句
So the melodies tend to be long; they tend to be asymmetrical.

所以旋律会很长会很不均匀

My paradigm here is the beginning of the

我举《布兰登堡第五大协奏曲》开始部分的例子
Fifth Concerto Grosso, in which the rhythm starts out

在这首曲子里开始的

节奏是十分整齐的
It's like a machine gun, almost, or a sewing machine,

就像一支机关枪一样或者说像一部缝纫机
or some kind of repetitive process there.

或者其他的什么在那儿重复工作
