Movie where Music Teacher Inspires Rebellious Kids to Love Classical

Can't remember the name of a movie that I watched in Turkish dubbed version on Inatbox. Can anyone please help me remember this movie? It's about a talented young musician who, due to a case of mistaken identity, ends up teaching a group of rebellious kids how to play classical music. Despite their initial resistance, the kids gradually develop a passion for music and form a tight-knit bond with their teacher. As they prepare for a prestigious competition, they face various obstacles and challenges, but ultimately learn valuable life lessons along the way. I can't seem to recall the title, but it's been on the tip of my tongue for days. Any ideas?
