Fender Rhodes electric piano, harpsichord, celesta, synthesizer and tack piano. The celesta was invented in 1886 by the Parisian harmonium builder . To the orchestral forces he added a harpsichord and celesta. The celesta or celeste is a struck idiophone operated by a keyboard. This technique can be heard in his "Music for Strings, Percussion and Celesta". The celesta is a transposing instrument; it sounds one octave higher than the written pitch. The re-recording is recognizable by the addition of flutes and celesta in the beginning. The work is notable as Tchaikovsky's first use of the celesta. The celesta part is normally written on two braced staves, called a grand staff. This motif is developed by the celesta and strings in the middle 8. Chausson is believed to be the first composer to use the celesta. George Gershwin included a celesta solo in the score to "An American in Paris". Steven Wilson uses the celesta on various tracks in his solo works. This part is nowadays sometimes taken by a celesta. The model was later updated in 2017 and is currently known as the Hyundai Celesta.
