Kids stuck at home across the world are signing up at Julia Segal's online platform, QuaranTunes, to learn to play musical instruments, explore music theory and even have voice coaching. Segal, just 16 and a Gunn High School junior in Palo Alto, Calif., began QuaranTunes after giving music lessons to her younger sister, who was restless from being cooped up at home. From there, the idea blossomed. On the platform, teen musicians like herself volunteer to give online music lessons for free to students aged 4-14. All donations, which have already topped $1,000, go to the CDC Foundation to help fight the pandemic. From a small start, QuaranTunes now hosts lessons for kids on the U.S. East Coast, Europe and India. 'It doesn't matter where you are around the world, you can participate in this either as a teacher or a student because it is a strictly online platform," said QuaranTunes COO Naama Bejerano, aged 17.
