Mathematics professor fixes the projector screen (April Fools' prank)

If you are an adult or a teenager learning the piano, then this could be the most important invitation you will ever receive.

Here's why:

Most people are really keen when they begin learning to play the piano or keyboard, but many soon give up because they find reading music notes too difficult.

They feel disappointed and frustrated. Why?:

They cannot find the notes on the piano keyboard.
They struggle to remember which note is which on the staff.
They confuse the bass staff notes and the treble staff notes.
