This project is for violinists! Click on the button that is associated with the string that you need to tune. If you want to play double, triple, or quadruple stops, you can click on two buttons, and both strings will play.
I used YouTube videos for the sounds. The violin was created by me. I know it looks like a double bass, but it has a chin rest, so... The code is all mine (There is no significant coding in this project though. The hardest part was drawing the violin.)
