You are a genius. Now you just have to make a cooler sound... My suggestion would be to use some sort of gear-work rapidly triggering a touch sensor that corrugates the sound into a sort of rapid pulse. Then you could try for some simple LFO (yeah right!)
That's a counter weight. The string around my finger turns the blue angular sensor and this is how the RCX finds out where on the "keyboard" that my finger is pointing. The counter weight is necessary for the string to rewind when I move the finger back.
It's not that difficult. I used the standard Robotics Invention System 2.0 that came with the set. I have two parallel program strings: The first reads the rotation sensor and displays it. The other string is activated by the touch sensor and splits the rotation sensors value into 25 cases by 5 levels of yes/no switchpoints. Each case gets a frequency.

@MrErnijs - Yes, but the point was to make a LEGO piano.

would this be possible with multiple fingers?

In that case each finger should have it's own string.
