celesta

The celesta () or celeste (), also called a bell-piano, is a struck idiophone operated by a keyboard. It looks similar to an upright piano (four- or five-octave), albeit with smaller keys and a much smaller cabinet, or a large wooden music box (three-octave). The keys connect to hammers that strike a graduated set of metal (usually steel) plates or bars suspended over wooden resonators. Four- or five-octave models usually have a damper pedal that sustains or damps the sound. The three-octave instruments do not have a pedal because of their small "table-top" design. One of the best-known works that uses the celesta is Pyotr Ilyich Tchaikovskys "Dance of the Sugar Plum Fairy" from The Nutcracker.

The sound of the celesta is similar to that of the glockenspiel, but with a much softer and more subtle timbre. This quality gave the instrument its name, celeste, meaning "heavenly" in French. The celesta is often used to enhance a melody line played by another instrument or section. Its musical parts are often the duplicate of a theme played on flute, harp or piano; sometimes even a real solo part. It is also used in chamber music, but there are very few concertos written for it. The delicate, bell-like sound is not loud enough to be used in full ensemble sections.
