Apparently listening to Baroque Era Music (50-80 beats per minute) while engaging in activities that require focus (working/reading) can have a positive influence on efficiency.
I can’t seem to find any solid evidence to why this is, possibly it has something to do with getting your brain into an alpha state. But again I can’t seem to find any solid evidence.
That being said it seems to help me. Placebo effect or not, I’ll take it!
