Grab a cup of cof­fee, put on your think­ing cap, and start work­ing through this video from Minute Physics, which explains why gui­tars, vio­lins and oth­er instru­ments can be tuned to a tee. But when it comes to pianos, it’s an entire­ly dif­fer­ent sto­ry, a math­e­mat­i­cal impos­si­bil­i­ty. Pianos are slight­ly but nec­es­sar­i­ly out of tune.
