i think giving him guitar or piano lessons will be the most effective way of introducing music.. for me old school pa din ako in terms of "making music" not the so called musicians of today that presses a keyboard
and a drum machine and call themselves musicians.. 
i agree. music lessons would be the way to go; a door into creativity, if you will. i always grew up with music around so when i started getting lessons, it opened up a whole slew of possibilities for me to make music from piano to drums, bass and guitar. my foray into production opened up even more possibilities because i found out about manipulating sound and learning more about how my favorite records were recorded and put together.
