I played viola for 10 years or so, and Fantasia on a Theme by Thomas Thallis, composed by Vaughn Wiliams was definitely the hardest thing I've played. In high school we performed it with the city's symphony, which was an honor. It was difficult because it calls for two orchestras, so two conductors, and all the parts sound really different at times so it's hard to know if you're in sync with the other musical sections. It's one of those musical pieces for me that, if you get lost, good luck getting back on track again with the rest of the orchestra. When I first sightread it, I was like, "how am I ever gonna play this?" So it was very satisfying being able to perform Fantasia several months later. :)
My main instrument is flute, and the hardest piece I have attempted (and successfully performed) to date is Cécile Chaminade's Concertino op. 107 for flute (and piano or orchestra). It took me a year to master it, and I performed it for my final graded performance recital upon graduating university. My husband (boyfriend then) accompanied me on piano.
Here's the piece in question. This isn't me playing, but I like this rendition of it. It's damn near perfect.
i used to play the clarinet and i don't remember the hardest piece i tried to play, i quit on it and joined choir because i didn't want to stop chewing gum in class (who knew that sugary gum ruins the clarinet rod :P )
I play piano, organ, and flute. I find organ the hardest since it takes so much coordination. I would say some pieces by Bach and Duruflé have been the hardest. (The easiest have been Satie's Gymnopédies on flute, which are some of my favorites.)
I'm only in a middle school band in a small school but I play flute and we are playing a March that was arranged by James swearington or something like that. It is really fun but hard to prepare for a concert that we are doing 4 other pieces in that are all difficult
Would it be impressive if I said that I can basically play this? 😏 Only thing is I don't have the double splash cymbal set-up (or a even full kit to play, at this moment in time... I moved recently), but otherwise I can basically play this note for note. The most difficult part is the "count" in some places, but that irons itself out after practice and repeated listens... 😁
I've played Guitar for 7 years (on and off) and i tried to play Satch Boogie which lasted all of 30 minutes, the hardest one i've prob had a decent go at could be Free Bird upto and inc the 1st minute of the solo.
