たのしくれんしゅうオンプモン is an iPhone app developed by YAMAHA MUSIC FOUNDATION APPS. It is designed to support parents in making practicing at home enjoyable for children attending the Yamaha Music School "Preschool Course".

With this app, children naturally develop a desire to play music. Parents can set practice start times in advance and receive push notifications to remind their children to start practicing. This helps establish a daily practice routine and makes it easier for parents to encourage their children to practice.

The app provides a fun and interactive way for children to practice music at home, addressing the common concern of parents who find it challenging to motivate their children to practice. It is a valuable tool for parents looking to support their child's musical development.
