Hello, teachers. Describing this picture, could I say, "I see a girl playing a piano."? I am referring to the act of playing the instrument (as a physical object), not the ability to play the piano. Could I use "a" or should I still use "the"?
In various dialects of English, you'll hear "She's playing piano", She's playing a piano" and "She's playing the piano". I'd use the third for that picture.
I wasn't suggesting that they meant the same thing. I wasn't clear. I simply meant that, without further context, you might hear all three of those from people you showed that picture to.
