I have been using tunes for 10 fingers for a 5 year old, however I may be taking on an 8, 10 and young teenager on as total beginers. Do any of you have any suggestions for suitable beginer books for thier ages- particularly the teenager.
(This is for piano by the way)

I've tried quite a few different tutors for teenagers - Tha Classic Piano Course by Carol Barratt, and It's never too late to play piano by Pamela Wedgwood are both for older beginners. There's also a Michael Aaron piano course for older beginners. Alfred also do books for the older beginner and I tried this one out with a teenager last September. She says she likes it, and is romping through it. Whatever tutor I use though I always use supplementary books and get them on to "real" pieces as soon as I can.

Probably the best thing for you to do would be to go to a music shop and have a look at the various tutors - there are loads of them and you'll be spoiled for choice.

For older teenagers a good book is Carol Barratt's "The Classic Piano Course" for older beginners - Book 1 - Starting to Play. It's fairly self-explanatory, and moves quite quickly.

I use James Bastien's The Older Beginner Piano Course for my adults, and have used this successfully with teens in the past-it gets them playing chords early on which makes the music sound good straight away, and I feel has a good balance of specially written, folk tunes, famous classical tunes, so they are playing tunes they recognise as well as reading new music. I use Carol Barratt as well-usually more for people who have learned previously, as after the beginning it moves a bit faster than I really like. The James Bastien book is from the USA so talks about quarter notes, etc, but I don'f find that a problem. Also worth looking at Microjazz for Starters, by Chris Norton-I use this as a duet sight reading book as all the pieces have a very pleasant, jazzy style accompaniment, but it is written as a tutor book. It's rather short, though, so worth having book 2 ready! Hope that helps.

I have this one as well and I too use it as a sight-reading/duet book, alongside whatever other tutor I'm using.
