I want to perform something that SOUNDS impressive and technical to an non musical audience, but that wouldn't be out of reach for me to learn.
Er... Ernesto Lecuona (1896-1963), Cuban composer... If you find Malaguena too difficult, try his "Danzas Afro-Cubanas" which are easier and equally exuberant.Best wishes,Bernhard.
LECUONA!!! COME ON!!! Sombody take my advice and learn lecuona!! The best show off pieces that arent hard!! Blaahh.. look into it... He's the best! Malaguena is so easy! AND it sounds Enormous! Plus like a whole book of other pieces
I've been wanting to enter my high school's talent show. It's in the winter
You may try Albeniz's Leyenda. It sounds very BID and it is easy to master.
One suspects (and indeed hopes) the OP has graduated highschool and advanced beyond intermediate in the intervening eight and a half years. In any case, the competition is long over.
