Hi, everyone. This is my first post. I’ve discovered this incredible forum a few weeks ago and have been busy reading through it all. (Haven’t finished yet!).
Here are a few suggestions for show off pieces that are far easier than the ones suggested so far, but sound very impressive to the uninitiated:
Mendelssohn’s Spinning song (Songs Without words op.67 no.4 - This was one of Rubinstein’s favorites encores. There is a clip of him playing it on the Art of the Piano video).
Bach’s Giga from Partita no. 1 in Bb. (Rosalyn Tureck used to play this as an encore – very flashy, with lots of crossing hands but not very difficult).
Scarlatti – There are hundreds of sonatas out there (about 600) with lots of fast runs, crossing hands, etc. Three that sound much more difficult than they are (Pletnev has recorded them at breakneck speed, and if I recall correctly Ivo Pogorelich also has recorded them) are K1 (in D minor – a two voice invention), K27 (in C# minor - very lyrical with lots of crossing hands – Michelangelo plays it on the Art of the Piano video) and K24 (in A major – far more difficult than the previous two)
Prokofiev – Prelude Op. 12 no. 7 (nice melody on the left hand, with a fast broken chord figuration on the right, plus some glissandi).
These are all ABRSM grade 8 or below, so they should not take two years to learn!
And if you want to go up a notch you may try:
Chabrier - Bourée Fantasque.
Villa Lobos – O cravo brigou com a rosa (The clove quarrelled with the rose) from “Cirandas” (no. 4) – very virtuosistic beginning and end with a lyrical middle bit – based on a Brazilian Nursery rhyme, another of Rubinstein’s encores (he was a great champion of Villa Lobos’ piano music). Easier than “A prole do bebe” that someone mentioned. There are 15 “Cirandas” (a ciranda is a nursery rhyme that children sig while holding hands and moving in a circle). You may want to listen to the others (There is a Naxos CD of them, played by Sonia Rubinsky – and Brazilian pianist Cristina Ortiz who lives in London frequently performs them).
Best wishes,
Bernhard
