What you are thinking of is PanPipes which are also lovely for little ones once they have got the hang of blowing across the top (like getting a note off a milk bottle) and aparently you can make yourself using drinking straws but I’ve not got round to trying that one yet.

And I’m going to risk being called a pedant now, stictly speaking those thigns with metal bars you hit aren’t xylophones they are glockenspiels although most toy companies don’t seem to know this…. a xylophone has wooden keys (and sound oh so much nicer!)

We have recorders that I found at the dollar store, a harmonica, maracas (can only find one right now), drums, and my most recent, awesome purchase for $2, is a Fisher Price Puppy Xylophone — sorry if that isn’t spelled correctly — that has buttons and as well as a bone on a string to hit the keys with. It also has wheels underneath so it can be pulled and when they do that, it’s little tail wags. Very cute and they LOVE it. I like to make instruments too, like shakers, and such.
