Which composers dad made him get up in the middle of the night to sing till morning?

The composer you're referring to is Wolfgang Amadeus Mozart. His father, Leopold Mozart, was a musician and composer himself, and he recognized Wolfgang's prodigious talent at a young age. Leopold would often wake him up in the middle of the night to practice and perform, believing that rigorous training would help develop his son's extraordinary abilities. This intense regimen contributed to Mozart's remarkable skills as a composer and performer.
