6. Background
   • JavaScript programming practice for my work
   • I am an amateur drummer and wanted to include special features for drummers in this program.
   • Wanted to write a generic program for any OS and Web browser. (I know user interface is not as good as apps for each platform.)
   • I will use this program everyday. Bug fix support will be continued until summer of 2018 or until I get bored.
