Questions & Answers about El ritmo de esa canción es rápido.
In Spanish, singular countable nouns almost always need an article (el, la, un, una) unless there’s a specific reason not to use one.
Here, ritmo is a specific thing (the rhythm of that particular song), so it takes the definite article el:
- El ritmo de esa canción es rápido.
(The rhythm of that song is fast.)
Leaving out el (Ritmo de esa canción es rápido) sounds incomplete or wrong in standard Spanish. English is more flexible and sometimes allows you to drop the in some contexts, but Spanish generally does not here.
Spanish uses de to show possession or association, where English often uses of or the possessive ’s.
- El ritmo de esa canción = the rhythm of that song
- English could also say that song’s rhythm, but Spanish does not use an equivalent of ’s.
