Writing for two pianos?

After seeing my new teacher play in a very interesting two-piano recital last weekend, I've been wanting to compose for two pianos, but I haven't any idea where I should start. Any advice or references you could lead me to? Thanks in advance. :)

I don't know any 2-piano pieces, but I do know some 4-hand (one piano) ones. Gazebo Dances by John Corigliano is a good place to start.

Mozart wrote a concerto for three pianos, and 1 (or two?) for two pianos.

Its just like writing anything else. The biggest thing is just to do it and not let a big project scare you. Jump in head first, if it doesnt work, take note of exactly what went wrong and try again...like I said: its just like writing anything else.

Most of the 2 piano pieces I've seen are jazz or blues. Maybe you could at least get an idea from some of that stuff if thats not actually what your writing.

In jazz/blues duets one piano usually takes the melody/riffs (improv a lot of the time, but still good for study of concept) for 8, 16, 12 or 24 bars (depending on the style) while the other plays a standard rhythm progression and a bass line. They then swap parts and repeat. This might be a fun way to go about starting a 2 piano duet, even if it is in a classical style.

Also remember, a lot of composers (especially Film composers today) originally wrote orchestral scores for two pianos and then arranged them.

There's a lot of 2-piano or 1-piano/4-hands repertoire out there, it all depends on what you're looking for.

There's a very nice Poulenc Piano Concerto for two pianos (in D minor), there's a Mozart concerto for 3 pianos (although usually the 2-piano version is performed), and another one for 2 pianos, there are also piano duets by Mozart and many other classical composers, and also Bartok, Ligeti and Kurtag have all written for two pianos. It really all depends on what you're looking for :)

Thanks guys. :)

Think of it like any other small ensemble composition only your using just pianos. Don't restrict yourself.
