Task: Question Answering
Input (English): Passage: I started playing the piano when I was a young boy . My mother got a brand new piano and I thought it was the most amazing thing ever . I walked up to it and pushed down on one of the white keys . I sat down and started to hit more of the keys . There were white keys , and fewer small black keys in between some of the white keys . I hit the keys until I started to recognize notes from songs I have heard . I practiced pressing the keys over and over until I matched the noises each key made with the sounds of songs I liked . \ \ I thought . I could now listen to any music I wanted to simply by practicing more and more until I learned it . Eventually I learned more about music , and that each key had a ' note ' . I learned that certain notes sound good together , and I could play those notes in any order I wanted , and it would sound good ! Some notes do n't sound good with other notes , so I also learned which notes to avoid while practicing . The piano is a great instrument to learn music on , you can play anything you want ! Question: When did the boy learn that there are 12 notes? Option1: Before he started playing Option2: When he began to learn the music
Output (English): When he began to learn the music
