Celesta is a musical instrument devised by organist Auguste Mustel in Paris in 1886, about 130 years ago. It has a keyboard, and it looks like an organ in size and shape, but the sound is completely different, and it passes very well, even though it is a small, pretty sound.

Inside the Celesta, there are musical scales of metal sound plates resembling a metal lyre. It is a percussion instrument that has a keyboard action that hits it with a hammer to produce a sound.
