The Music Extension is an extension added in Scratch 3.0 that allows users to play notes and compose music in Scratch. These blocks use sampled instruments to create the sounds. Before 3.0, the music blocks could be found in the Sound Blocks category. The Scratch Team moved the blocks here in order to make Scratch easier for New Scratchers to use.[1]
