He looks like a rabbit I tried to bond with one of mine. His black & white coloring (like a piano keyboard) earned him the name (from the rescue) of Sebastian -- a nod to the composer Johann Sebastian Bach.
But maybe any name you associate with a piano could be an option.
If you're not a musical-type person, you could consider a theme-based name. Here's a list I created awhile back...
You could consider PLANT names like Basil, Pepper, Pumpkin, Rose, Daisy, Ivy, Lily.
Or "SKY" names like Orion, Pluto, Neptune, Draco, Galaxy, Nebula, Venus, Galaxy.
Or ROCK names like Quartz, Malachite, Copper, Clay, Diamond, Silver, Marble, Slate, Coal.
Or WEATHER names like Blizzard, Volcano, Storm, Dusty, Sunny, Cloud, Rain, Frost
Or based on COLOR (depending on color of course) like Ginger, Cinnamon, Onyx, Vanilla, Cream, Snow, Midnight, Shadow, Cocoa, Butter, Spot, Speckles.
Food names can be in themes as well…
