A classic example is the LCD Soundsystem song “All My Friends.” The song develops extensively, without an obvious lyrical structure. There are certainly repeated melodies, various layers coming and going, and a strong lyrical narrative, but it never deviates from that repetitive piano part.
There are a ton of pitch corrector plugins out there to make sure you’re fully in tune and sounding great — and no, you don’t need to go full Auto-Tune. If you’re a bit of a perfectionist though, you may want to hand tune them yourself. Head into the Audio Editor to find an option called Flex. From there, you’ll be able to tune any of your vocals by dragging them up or down to the correct note or fine pitch, or even flatten out the vibrato.
