Four-colour theorem - help!

I've just found a simple solution to the 155-year-old four-colour theorem. I'm not sure what to do with it – I'm afraid to show it to anyone because they could steal it. Please, help!

What I am working on

Composing:
Adagio for oboe and two horns (f-moll)
Suite for piano (D-dur)
Trio for flute, violin and harp (e-moll)
Requiem for 3 voices a cappella (C-dur)
Theme and variations for piano (G-dur)

Click to listen to excerpts. Recorded on a computer, except the Requiem - I sang, so forgive me for the quality!


For the next Arts Evening I am preparing the following "potential" pieces:

Organ
Buxtehude – prelude and fugue (fis-moll)

Piano
Mozart – sonata No. 1 (C-dur)
Mozart – sonata No. 4 (Es-dur)
Beethoven – sonata No. 14 "Quasi una fantasia" (cis-moll)
Chopin – etude No. 23 "Winter wind" (a-moll)
Rachmaninoff – prelude No. 5 (g-moll)

Violin
Corelli – sonata No. 9 (A-dur)
Bach – concerto No. 1 (a-moll)

Arias
Scarlatti – "Gia' il sole dal gange"
Donizetti – "Una furtive lagrima"


Let me know what you like - I'll compose faster! ;)
