Here is a virtual interactive cello I made! The bow follows your mouse. Press the keys 1, 2, 3 and 4 to control where you place your fingers on the fingerboard. The numbers and lines will show you where you are on the fingerboard and what finger you're using. Use the key '0' to go back to the open string. Press space to change the background color and press 'c' to change the color of the cello. Please enjoy, and tell me if you have any questions or suggestions! Also, sorry if the sound quality is a little bad, I recorded it using the scratch microphone.
All of the art is entirely by me and all the sounds are from my own cello (I have played the cello for about 2 years). I drew some inspiration from @TincanGames.
