**Two newly discovered pieces of piano music by Wolfgang Amadeus Mozart are to be performed in the Austrian city of his birth, Salzburg.**The pieces had long been in the archive of the International Mozarteum Foundation but only recently were they identified as compositions by Mozart.
The foundation has released very few details about the music.
It is to be played at a house where the composer lived from 1773-1780, which is now the Mozart’s Residence museum.
Posthumous discoveries of Mozart works are rare but not unknown, the BBC’s Bethany Bell reports from Salzburg.
In January, a piece by Mozart that had lain undiscovered in a French library for years had its first performance.
Mozart wrote more than 600 known pieces of music before his death in 1791 at the age of 35.
He began composing at the age of five and his works include operas, chamber music, choral pieces and piano concertos.
An official at the International Mozarteum Foundation told the Associated Press news agency that the compositions to be played on Sunday were “substantial pieces” composed before Mozart’s 10th birthday.
