I think of you learn a piano keyboard in the context of theory, that all instruments thereafter will be easier to learn. My daughter wants to play drums, but we are having her learn piano in a course that emphasizes theory and rhythm first. Our thinking is that a formal understanding of rhythm will apply to percussion very well, and early exposure to theory will allow her to understand the role played by percussion in the overall music of whatever band she eventually plays in. She was highly resistant to the piano, but now a month into it is enthralled. She practices every day, many times more than once, and she is already reading music and understanding how major chords go together. I've got her practicing with a metronome and she's learning about steady timing right from the start.
