It's a good course if you really want to save time knowing what you need to create digital music. It's kinda like the guitar approach learn the chords, add some melody in the scale and you're done. The course is very good. Riley explains it quite well. Would be nice to have a bit more specific exercises in the future courses to target more specific areas. Overall I'd say get it if you want to get up to speed with creating chord progressions, getting to know a bit how it all goes to beatmaking.
