While you are enrolled at Piano Wizard Academy, you have the opportunity to collect pins of various instruments. You'll earn a PIN each time you perform a specific activity. When you perform that activity 30 times, you will obtain a gold pin. If you created an account and logged in you already earned your KAZOO GOLD PIN and a TRUMPET PIN! (You can see your points and pins in the right sidebar. Hover over the images for Pin information.)
So get cracking and collect your instruments and maybe you'll graduate with a Masters in Music!
