Description

EXCELLENT TOOL FOR PIANO LEARNING!

😓For piano beginners, it is very challenging to memorize all the keys on the piano in a short period of time, which prevents us from playing the piano right away. Even more frustrating is that the enthusiasm for learning the piano that we just ignited is likely to be extinguished.

🤗As you know, learning the piano is a process, but we can still use tools to make the process faster and easier. The Removable Piano Keyboard Note Labels present the key notes in a visual way, helping you to start playing and practicing immediately when you are not yet familiar with the keys.

🎹The Removable Piano Keyboard Note Labels is made of silicone, and connects the labels in series, so there is no need to stick to the keys like piano stickers. Easy-to-install, Easy-to-remove, without leaving any residue, and keeping your keyboard clean and tidy.

🎹Showing the note of each key with double staff, which helps to find the corresponding key from the keyboard faster, because all piano scores use the treble and bass staff structure.

🎹When you start to know the keys and become familiar with the octave rule, you can remove the note strips from the keyboard. Of course, if you feel that you are not skilled enough, you can put it back at any time.

🎹Fits standard sized 88-key pianos. Perfect for grand pianos, upright pianos, 88-key digital pianos and keyboards.
