These may not be the cool songs, but they're the ones that have been around forever and everyone knows.
I have a bit of a learning disability and find some instruction books a nightmare. I had very little trouble with this one though, even though I couldn't read a single note when I started. You may need other books later to fill in a few blanks, but in my opinion if you start with these books and some determination there's no way you're gonna quit.
The only knowledge I had of Kenneth Baker before buying this book was that he played jazz trumpet. Going from trumpet to keyboards isn't an obvious choice, but at this stage there's no problems. Later on, there's a couple of confusing points though but that's when you'd be at a stage to want a few actual lessons.
The playing part of the book starts you really gently with Merrily We Roll Along. It uses a total of 4 notes (middle C, the D above, E & G)and two chords (C & G), one of which at least you'll find in virtually all songs. Anything more complicated then is likely to make you chuck your keyboards out the window.
Once you've got that right, go on to Barcarolle. The only part of that music I heard was played really fast, whereas this little chunk is more of a waltz.
Then you go on to "Lightly Row", a nice little piece once you've mastered the chord patterns.
Other songs in this book vary as there are several editions. Whichever version you have though, you have some fun songs where virtually all are fun to play for years to come
