A. Features 1. No glue or pasting needed: 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 as with 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. As most piano sheet music uses the treble and bass staff structure, this can assist in finding the corresponding keys on the keyboard more quickly. 3. Beginner - friendly: It's not necessary 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: Once one starts to understand the keys and get familiar with the octave rule, the note strip can be taken off the keyboard. Of course, if one feels not proficient enough, it can be put back at any time. 5. Compatible with 88 - key full - size pianos: It's suitable for standard 88 - key pianos, such as grand pianos, upright pianos, 88 - key digital pianos, and electronic keyboards. B.
