I am a noob so don’t expect much. I made this in one day Space to change the instrument. Z for an interesting effect. I have absolutely no idea why I find choir so amusing. Only 189 blocks and 28 of them are just to change the instruments! No more blocks are required. I used a method that reduced the number of blocks drastically and provides more flexibility. For example, it clan play multiple notes at once.
Everything by me. Originally composed by Leonard Cohen I took the music sheet from Rockschool Ukulele Grade 5 book. Inspired by https://scratch.mit.edu/projects/703097599/
