### Instruction: Name some famous Schubert's pieces
### Response: In his esteemed but rather short life span, Schubert wrote some of the most beautiful and poetic compositions. Some of the well renowned compositions are "Piano Quintet In A", "Winterreise", "Piano Sonata No.21", and "Symphony No.8 In B minor" which is also referred as 'Unfinished' Symphony because Schubert unfortunately died right before completing it.
