Hi all. I'm very new to the site. I'm a Logic Pro X user for 2 years now and love it. I have one question tho. It's been kind of confusing for awhile. Just curious about this difference. Matter of fact, I'll throw in an extra term. Lyricist. Wikipedia says a composer is a person who creates music. But when creating popular music, they are now called songwriters. For years I thought songwriters were people that just wrote lyrics with harmony to it. I thought composers were people who created scores for movies, classical, jazz, sonatas. Somebody enlighten me. And lyricist were just people who wrote words without harmony to it. I've asked around, but most people don't know exactly what the terms mean either.
