Would like help on website development and design

Hey all, I am a computer science engineering student .I have actually undertaken a project at hand which will help me develop my skills .The project is a web based platform for pianists .In that platform I am going to be posting notes and the way to play a song .For the front end I thought I will use html and for the back end I thought I’ll use php .There is a similar platform for guitar and even my platform I want it to be the same but for a pianist or a keyboard .Any suggestions on what I should do will be very helpful .
