Learn Spanish (Latin America): Me gusta el coro, por eso participé. - I like the choir, that's why I participated.

In this lesson, you are learning the preterite (past) tense. For regular verbs ending in -ar like participar, the "I" form in the past tense ends in an accented -é. So participé means "I participated" as a completed past action. Without the accent, participo means "I participate" in the present tense.

Why use Me gusta for "I like" instead of the word for "I" (yo)?

The verb gustar translates more literally to "to be pleasing to". So Me gusta el coro actually means "The choir is pleasing to me". We use Me (to me) instead of yo (I) because you are the one receiving the feeling, while the choir is the subject doing the pleasing.

Does por eso always mean "that's why"?

Yes, por eso is a very common fixed phrase that means "that's why" or "for that reason". Literally, it translates to "for that". It is the most natural way in Spanish to link a cause to a result, just as it is used here.

Is it normal to mix the present tense (Me gusta) and past tense (participé) in the same sentence?

Absolutely! Here, liking the choir is an ongoing, present feeling, but participating was a specific, completed event in the past. Spanish uses tenses to match the exact timing of each action, just like English does.
