What studies say

In one study, music with lyrics hurt verbal memory, visual memory and reading comprehension compared with silence, while lo-fi instrumental music didn't clearly help or hurt (a study on music while studying). Another found that preferred background music reduced mind-wandering on an easy, repetitive task (research on preferred background music).

Match the sound to the task

UC Berkeley's student wellbeing guide suggests silence for reading and notetaking, ambient noise for brainstorming, and relaxing or instrumental music for reviewing (UC Berkeley student wellbeing).
