"... and got rid of it by putting it in the trash over a 4 week period. I broke up the string harp with a sledge hammer. Used a drill to loosen the strings then just cut them off." 

Said William50 in last night's "Snow Car" café

He was referring to something I said in passing in an earlier post — that I had looked up "Flatter!," because it was part of an image on a card that I found in the piano bench, which I was emptying out because I'm getting rid of the piano. 

Breaking up a piano made me think about this great 80s video where they destroy a piano: 

And since you mentioned the harp inside, we must remember when Harpo Marx went nuts on a piano and extracted the harp:

But here's how I responded to William50 (who may not have  noticed that I'd already revealed in the comments on the other post that I am paying a professional piano dealer to move the piano out of our house and to dispose of it properly):
Meade suggested doing something like [what you did]. I see multiple reasons to prefer to pay a reputable piano dealer $360 to swiftly spirit the whole hulk out of the house. 
1. It's a lot of work taking the thing [apart] and lugging it [out to] the street, consuming time and effort and possibly resulting in injury to yourself and damage to doorjambs and floors. 
2. It would sit out there on the terrace for all to see and to find ugly and offensively wasteful. 
3. It will burden the city -- and the taxpayers -- to need to pick up these pieces and carry them away. 
4. The reputable piano dealer is experience[d] in disposing of pianos and may find an actual home for the intact piano. 
5. The piano will sit in its usual place, unmolested, until professionals come in and skillfully remove it in one piece. This is a company I have used 3 or 4 times in the past to move this piano from room to room, and I [trust] them to do it well. 
6. I like supporting a good local business! They deserve to be paid for the work that they do. You don't have to use your own labor just because you (or your partner) can perform labor. We're doing a lot of painting this winter, putting labor into that, but if I had a local business I trusted to do this work well and without needing to spend too much time in our house, I would be glad to pay someone. 
7. $360 may sound like a lot, especially if you believe your beautiful piano should be worth at least $5,000, but I choose to live in the real world, where prices are determined by supply and demand. Accept reality and make your time living in it as good as you can. Maybe you enjoyed sledgehammering a piano. I hope you did!
