He's got a theme and then he's got what we call an ostinato in music.

其一是主题其二是固定音型。

Once again we've been through this many times but what is an ostinato?

虽然之前已经讨论过很多次但我还想问 什么是固定音型？

Sometimes it's even in ostinato form.

有时候也可以是固定低音。

So we have ostinatos coming back into music here in the impressionist period.

在印象主义时期固定音型回到了音乐中。

All right. So we've got that as an ostinato bass.

好 我们已经了解这个固定低音了。

It's odd how many of these ostinato basses are in eight bar units.

真奇怪 有那么多固定低音是以八小节为单位的。

So every aspect of that melody, rhythm and harmony is controlled by this ostinato procedure.

因此这首曲子的节奏 旋律 和声都严格遵从固定音型。

All right. So let's put that behind us now and go on to talk about ostinato form.

好吧 那么我们暂且把它搁置一边我们接下来要讨论固定音型曲式。
