What exactly are the blue bars?

What do the blue bars represent, other than volume amplitude? Anything? They don't seem to be sound waves that change with the timbre of the sound (sine, square, etc.).
The green bouncing bars represent the sound volume on playback and the red bars on record. The blue wavy lines represent the actual sound sample points drawn as a graph. If you keep magnifying the blue waves, eventually, you'll get down to the PCM sample points which look like little squares on the wave.

That's what a normal, standard Audacity is supposed to look. Your tools may be a different size or in different places. That is a perfectly record piano solo and those are normal graphics.
