Which major works did Franz Schubert compose during his final year?

During his final year (1828), Franz Schubert composed a remarkable succession of masterpieces despite his declining health. His major works from this period include:1

• Orchestral and Choral Works: He concluded the Great Symphony (also known as the Symphony No. 9 in C Major) in March and completed the cantata Miriams Siegesgesang (Miriam’s Victory Song). In June, he worked on his sixth mass, in E-flat Major.1
