It is a metal instrument, comprising of a set of tubes of different lengths from each other. Due to these changes in lengths it can produce lower or higher sounds.
CELESTA by Juan De Quintana Machín – 1ºB
The celesta is a musical instrument similar to the upright piano. The difference is that a celesta has got metal bars in place of strings. For this reason, it is an idiophone instrument.
When hitting the metal bars, it creates a resonance on a wooden box,
making a “heavenly” sound, from which comes its name.
