Summary

The addition of sound playback is fundamental to the operation of many Scratch applications. In Scratch, sound effects and music playback are controlled through different sound code blocks. Using these code blocks, you can convey additional meaning and enhance excitement when your applications run. This chapter provided instruction on how to work with all of Scratch’s sound blocks and to use them to play audio files, drum notes, and musical notes. You also learned how to change the tempo at which drums and notes are played; control the volumes at which audio files, notes, and drum beats are played; and select different types of drums and instruments to be played.
