Features 1. No glue or pasting required: This piano note guide is made of silicone, with the labels connected in series. So, there's no need to paste it on the keys like a piano sticker. It's easy to install and remove, leaving no residue and keeping the keys clean. 2. Dual staff display: Each key's corresponding note is shown in dual staves. Since all piano sheet music uses the treble and bass staff structure, this helps you find the corresponding keys on the keyboard more quickly. 3. Beginner - friendly: You don't need to know the names of the keys or the position of middle C. Just place the note strip on the piano keyboard, and the installation can be completed in seconds. 4. Can be removed and reused at any time: Once you start to understand the keys and get familiar with the octave rule, you can take the note strip off the keyboard. Of course, if you feel you're not proficient enough, you can put it back at any time. 5. Compatible with 88 - key full - size pianos: It's suitable for standard 88 - key pianos, including grand pianos, upright pianos, 88 - key digital pianos, and electronic keyboards.
