I understand that there is a difference between the two, but I'm still confused. Are the terms "ostinato" and "motif" interchangeable?

1An ostinato repeats multiple times without interruption. A motif can appear basically at any time in any place.– Kilian FothCommented Jul 12, 2022 at 10:34

Also: "ostinato" has a fairly narrow and concrete definition. "Motif" has a fairly fuzzy and vague one, meaning little more than "a recognizable unit." You could use "motif" in talking about visual art to mean a certain visual element, but you couldn't use "ostinato" except as a metaphor referring to the musical meaning.– Andy BonnerCommented Jul 12, 2022 at 22:18

No. An ostinato is a sustained pattern, lasting many bars. A motif is a particular 'musical idea', that may itself last several bars, which keeps re-occurring during a piece.
An ostinato is particularly a rhythmic pattern that is repeated bar after bar, or in two or four bar sequences. A motif will pop up from time to time to remind us of itself.

2I think it would be good of you could make the difference between "sustained pattern" and "keeps re-occuring" more precise. (I have no idea what you mean)– EmilCommented Jul 12, 2022 at 7:02

Also, an obstinato brings along the idea that it repeats identically. But a motif (also called a motive) is often developed and lengthened into a more substantial theme later Commented Jul 12, 2022 at 15:23

1@nuggethead - seems comments can't be edited after 5 mins. So either scrap that one and write another, or leave it. I quite like it, thought it was quite clever! Somewhat apposite.– TimCommented Jul 13, 2022 at 9:54
No. They serve very different purposes.
A motif starting on a different note of the scale or in a different mode is still the same motif. Motives are defined by their melodic contour.
An ostinato repeats without variation, even when it clashes with the underlying harmony.
