 Therese sang in the Lichtental parish church, which Schubert had been attending since he was a child.For the church's centenary celebrations, the young Schubert completed his first mass in late July 1814 — the Mass in F, D.105 — and Therese sang the soprano solo at the premiere performance, which Schubert conducted himself.Schubert assembled an album of songs for Therese's brother Heinrich, the last of which is dated 1816.
