How do you take apart an upright piano?

there are many ways if u dont want ot be able to reasmble it afterwards take a hammer or better yet a sldgehammer or if u want it to be able to reassmble try using a screwdriver on the screws

if u really want to take it apart to small pieces use some explosives

Having had experience with a sledgehammer and an upright piano, I hope you are strong and in good physicall condition - it will take all day. My husband suggests a catapult ala "Northern Exposure" and I tend to agree.
