Playing instruments both relaxes and helps people to develop. That’s why we developed this app for people playing instruments. This is an app that can record the instruments, songs and musical goals they play. For example, you play the clarinet. You can record lyrics and notes of songs that you can play with the clarinet. This allows you to access it at any time. Or you started playing the clarinet on stage. You can record the venue’s information and the days you go on stage. Or if you have musical goals, you can do them. Musical life awaits you.
