|If you are going to be using an electric keyboard, than it won't be all that different from piano. (The keys on an electric feel different.)|
A point about terminology: An electric
instrument (such an electric guitar) produces its sound mechanically then transduces it (turns it into) an electric current, which is then amplified. An electronic
instrument produces its sound non-mechanically, electronically.
The most famous electric keyboard instruments are the Rhodes electric piano, the Wurlitzer electric piano, and the Hammond B3 organ, none of which have been manufactured for decades. None of these sounds anything like a piano.
As I pointed out before, you can buy all sorts of electronic
keyboard instruments that have buttons on them that make the instrument sound alternately roughly like a piano or roughly like an organ. How roughly depends on the quality of the individual instrument.
