What is this?
A QR code is a type of barcode which can contain links to webpages. Mobile phones with a camera and an appropriate application are able to read these codes and take you to the address contained within it.
This code will link to the page for Discovering Music, Mendelssohn: Symphony No. 4 in A major ("Italian") (Op. 90) when read using a QR code reader.
