NO! not a toy, a PROPER keyboard! I haven't looked at links, and no time tonight.
But try and go for a proper keyboard, full-size keys, and 61 of them if you can manage it. Our DS started music on our big Yamaha organ at a few months old; by 5 yrs was playing tunes, and at 6 yrs was reading music.
I taught recorder in primary school, as a TA, for ten years, but also did keyboard with Yr6, and percussion with Yr1 and Yr2, coaching the children to accompany the Christmas production each year.
The opportunity to create music is one of the most valuable and rewarding things you can do for a child. And as they get a bit older they can play in ensembles or shows at school.
Is the money the main problem? I have looked at links now, and personally I think all those would just be a waste of money; all right for a 2 year old maybe, but at nearly 5 DD wants a proper musical instrument, not a toy novelty.
Sorry if I'm being rude, but music is one of the things I've always been passionate about.
I'll come back tomorrow, and if you can give me an idea of what is the most money you could consider, I'll try and see what might be available.
Do you play any instruments yourself? What sort of music do you all like? If you don't already play keyboard yourself (and I get the impression maybe you don't) would you want to learn yourself, alongside her?
If you get a 'proper' keyboard, you will also need a decent stand for it, rigid and ideally adjustable.
And if you buy in a music store, don't be shy - HAGGLE over price, to get a good reduction, or get lots of other goodies included.
If you want to learn, I can 'talk you through' the early stages.
Thanks for your replies ferguson, . I can see your point with regards to getting the real thing. I was thinking of getting a toy ad then perhaps a digital piano next year as I would love to learn to play as well. I used to play the violin but was not very good at it .
