The image shows a set of four colorful keys arranged in a row on a wooden surface. The keys are red, yellow, green, and blue in color. Each key has a small hole in the center, which is likely for the keys to be inserted into. Below the keys, there is a label that reads "Auto Arpeggio" which translates to "Voice" in English. The label also has musical notes and symbols on it, indicating that the keys are used for playing music.
