Jonathan started to know piano from age 5 years 4 month after we bought second piano on April 2021. At first, he learned by autodidact from YouTube. After that, we introduced him (from his auntie) with piano application, and he showed enthusiasm on learning it.
Within circa 3 months, he completed all the lesson & songs from piano application.
From 13th of November 2021, Jonathan joined offline course at Andante Music School until second semester 2023. He also took Violin and Guitar lesson at Andante Music School, before move to ARTE Komunitas Seni Jakarta.
While for his younger sister Mikhaila, she started learning piano at the age of 4 years and 8 months, and she studied at YMJ Kelapa Gading. In addition, at the age of 4 years and 11 months, Mikhaila also began learning violin. As Mikhaila often watched his brother play the piano and violin, she quickly adapted to playing both musical instruments."
