Developing confidence with music theory (and using it in your electronic music) starts with a firm grasp of the fundamentals. You'll quickly learn about pitch, sharps and flats, the chromatic scale, accidentals, intervals and more. If you don't know what those are, you're making electronic music harder than it needs to be. Every time you want to learn something in music theory, you'll encounter these terms and concepts. If you're not comfortable with these terms and concepts then you'll be at a disadvantage in learning quickly.
Learning music theory is fun! But, not if it doesn't make sense. Do yourself a favor and sit down with this quick course and familiarize yourself with these terms and concepts. You'll be glad you did! Music theory is a wide, wonderful world and you'll need to know the language if you want to succeed.
