First, click the Green Flag. Second, click the colors for that letter note. Third, play songs along the beat! :D And yes, it's an online xylophone, but with piano notes! It's a bit strange, but the scratch note-box didn't have xylophone notes- ... Enjoy, and have a great day! :D
My savior for this project: @LilSportsGuy who is also my brother. Reason: I had to fix this, so, so, so many times. It wasn't until I asked my brother for help, that he said, "The notes aren't in the right place" (Like, my note order was A, B, C, D, E, F, G, C2, but not C, D, E, F, G, A, B, C2. I got the notes matched with the letters, though :)) So, then I had to re arrange the letters as well as the notes, which didn't take much time for me. In the end, you guys got to enjoy my awesome project that I coded- with help of course! :D Also: My brother plays the piano, and has been playing for a long time. Me, I play guitar, but right now (the time I published this) I am sort of in between a beginner, and a middle- level guitarist. :)
