I’ve never cared much for the trombone. It sounds okay when played among other instruments, but I don’t like listening to it played solo. To me it looks like a difficult and awkward instrument to play. I’ll put in a second vote for the harpsichord.
I can’t STAND saxophone. I don’t know why.
I don’t mind oboe, though.
One thing that has always bugged me-- in Beethoven’s Fifth in perhaps the second section (I know-- my knowledge of musical terminology is without peer) all of a sudden this tympani starts up THUMPTHUMP. . … THUMPTHUMP. . . THUMPTHUMP thumpathumpathumpathumpa just in a couple of spots and it has always seemed REALLY out of character to me.
Bag pipes. I think they were created by someone who hated music.
I have heard good bag pipe music, but maybe only one performance in a hundred is palatable.
Without trying to minimize the seriousness of the event, I feel like 9/11 was the worst thing that ever happened to bag pipe music. Memorial service after memorial service after memorial service, every time there was bag pipe music. I wanted to watch these services on TV, but started to change the channel whenever the bag pipes started. - I always wonder what percentage of those who are being remembered would’ve been driven crazy by the idea of bag pipes being played in their memory.
No.
I keep an open mind.
Accordion. It’s not that I can’t stand it, exactly, but the timbre can sound harsh to me. If it’s played pianissimo, it’s not that bad. Maybe it also has something to do with the quality of the individual instrument or the skill of the player.
I’m also not much of a fan of the standard repertiore of accordion music.
Add to my original the ‘Hammond Organ’ with the booga-chigga booga-chigga ‘Roll out the barrel, lets have a barrel of fun’ booga-chigga booga-chigga fucking loony grandma having a jolly old good time.
We called those horrific “instuments” flutophones at my school. We started them in elementary school and after having three kids learn to squawk on them, I thought my parents were going to lose their sanity! :eek:
On the other hand, I do sometimes enjoy the sound of a wooden recorder–though I, too, wonder why they are called by that name. 
IIRC, they were created more to scare your enemy at war rather than for music.
I like 'em in any case.
Worst screeching, nails-on-a blackboard, excuse for a musical isntrument ? – The Clarinet.
(By the way, piccolos rule!)
