worst musical instrument to listen to

The worst musical instrument is the one that is played badly: with little skill

The Stylophone and it’s the easiest of all instruments to play.

better to be in another country when they break out the bagpipes.

I can't find an audio clip, there was a one-time Batman henchwoman named Doe, who worked for Chandell (Liberace) and her schtick was she played the bagpipes so badly it drove one unconscious.

I knew there'd be those who dislike the bagpipes, but I love them. They are loud, yes, but when played by a skilled musician, they can elicit emotions of sorrow or heroism.

There's a Chinese wind instrument that sounds like a bagpipe on meth, but I don't know what it's called.

But it's just as excruciating to listen to as you'd think.

Not only Yann Tiersen
Astor Piazzolla has some absolutely amazing pieces for Accordion.

And the main theme in Il Postino is one of the best themes ever written for Accordion

When it comes to bagpipes, they can be excruciating... until you listen to musicians like Liam O'Flynn

Came here to say this. For some reason, every parade in Canada typically features a military band and there are always bagpipes... so many bagpipes.

Bagpipes are made from the skin of dead animals. The instrument was invented to repel invaders. They were never meant to be heard recreationally.

The only time I ever can tolerate them is when they are gently used in the background of certain middle-of-the-road pop songs such as Mull of Kintyre, or Rhythm of My Heart.

That's pretty horrible.

Sounds like a herd of wasps,

Vuvuzelas aren't a musical instrument, they're a torture device.

You ever see/hear the Great Britain Ukulele Orchestra? It's so good.
