Scordatura is when you tune a musical instrument differently than its usual tuning. It's like when you usually eat your favorite ice cream with a spoon, but one day you eat it with a fork. You're still eating the same ice cream, but the way you're eating it is different.
In the same way, musicians can change how they play the music by changing how they tune their instrument. For example, a violinist may tune one of their strings to a higher pitch than usual, making it sound different than normal. This can create new and interesting sounds that composers can use to make their music more unique and creative.
Scordatura is used in many different types of music, from classical to folk to experimental. It's a fun way for musicians to explore different sounds and techniques on their instruments.
