Digital pianos: are electronic musical instruments, often built to look like pianos, that electronically reproduce authentic piano sounds. Digital pianos have no hammers, strings, or soundboard; instead they have electronics and speakers. Digital pianos never need to be tuned, can include different instrument sounds, rhythms, recording capabilities, and can be used with headphones so you may practice without anybody else hearing you. Digital pianos are much easier to move, but do not hold their resale value like acoustic pianos. Little to no maintenance necessary.
