NOTE: PLEASE DOWNLOAD IT, OR PLAY IT ON TURBO SPEED FOR BEST PERFORMANCE. I made my own type of instrument with Scratch! It was planned to use a microphone, but I had lots of problems with that. So this uses a keyboard. It's still very hard to play, and if you master using this, it would be a great talent to have. If you are confused on how to play it, you should look at the instructions in the project for how to play each note. If you want to know how it works, let me explain it to you. First of all, each arrow key (besides up) has their own number. Left has 1, down has 2, and right has 4. Also, each note from low C to high C has a set number. C - 0 D - 1 E - 2 F - 3 G - 4 A - 5 B - 6 C - 7 So if you wanted to play a D, you would press left (since they both are equal to 1), and if you wanted to play an E, you would play a 2, and so on. Low C would be nothing at all, since it is zero. If you wanted to play a B, which is a 6, you would have to play right (4) and down (2), so they add up to 6. You will notice that there is a guide for what buttons to press on each key on the top right corner. Notice the pattern, and try to understand it well. Now here is how to play black keys. To make a sound, you either have to press B, N, or M. B is flat, N is natural, and M is sharp. So to play a B sharp, we would have to press right, down, and M. The up arrow will immediately stop all sounds. Keys 1, 2, 3, and 4 change the octave. The keypad starts on octave 2. 1 would be the lowest, and 4 would be the highest. I'm sorry if you still can't understand any of this. In fact, I don't expect many people will understand it at all. But if you don't understand it, leave a comment telling me what you do not understand, and I will try to clear it up for you. ;)
