Low-fidelity music, or lo-fi, is music that is recorded with intentional imperfections, such as misplayed notes, environmental noise, low hum, or phonographic audio imperfections. Unlike hi-fidelity, or hi-fi, which is the high-quality reproduction of sound, the imperfect elements of lo-fi music are a popular choice when it comes to the positive results when studying is concerned. So, why would imperfect sound be one of the perfect genres to study to? Sit back and take a listen as you hear why. Lo-fi music helps the front lobe in our brain to focus – those flaws or low hums can also put the brain in the mindset to focus.
