Learning how to read piano notes faster no longer has to be at the cost of your piano. I'm talking about those messy piano key stickers, or marker pen, that take forever to set up and then wear off after a few days... oh but leave sticky residue that ruins your piano's precious ivory keys. This is why I created The Piano Rake: the better alternative to stickers or marker. Installed with seconds and made from a non-stick, durable and flexible silicone that will allow the keys to move freely. In fact, each tab will move with the keys so that you know exactly which key you are playing. The Piano Rake (Piano Guide) fits all full-size key pianos and keyboards. It is specifically designed to fit the specifications and dimensions of all modern keyboards. Every single brand!
