Did I use the past tense correctly?
Is this correct-
"Él estudiaba el piano en el Invernadero Nacional de Música en México Cuidad"
I want to say he studied piano in the National Conservatory of Music in Mexico City, but I am not sure about the past tense, or even how I translated National Conservatory of Music. Gracias.
Your use of "estudiaba" seems right to me. You used the Past Imperfect, which is used when something happened in the past, without a definite ending point to the action. Your example fits that. Let's wait for the pros to give the definitive thumbs up.
