How to Do a Mean Improvisation Piece on the Keyboard?

To improvise is to make up the music as you go. Some great artists improvise their solos live rather than play the same old album version. Improvising well is about being able to stay in key and stay in the mood while playing through the ideas in your head.

Pick four simple chords to play with your left hand and make up a rhythm to play on the root of each chord with your right hand.
Add more fingers as you become used to the one note and remember to keep on producing different catchy rhythms.
Gain speed on your melodies and begin to use scales and arpeggios to add interest. If you find a riff you like, then remember it. You can always repeat a riff you like and use it as a theme to revert back to.
Start using chords with your right and experiment on what chords on the right hand will cooperate with the left hand.
Use unique scales like the blues scale on the right hand(1, b3, 4, b5, 5, b7, 8 in major intervals) and use common chord progressions like the blues chord progressions on the left hand (I4x, VI2x, I2x, V1x, VI1x, I2x)
Improvisation takes a bit of time and skill. You can probably find a jazz improv. CD on the internet to help you stay in key.
