I think what is most imortant, SRS, if parents want their childeren to be musical... beyond music lessons, which BTW turned me off of being a musician as a li'l one... Have a wide variety of music on at home and it is most important to begin a dialogue with them about it... Let music be important, share likes and dislike, anything that piques interest... the choice of instrument, and genera should come naturaly after that...

All the best! ttr
