I bought this as I have long been after a transcription of " I wish I knew...". Sadly the transcription here is not the famous version* used on the BBC film program for decades. Theres nothing wrong with the version here, but its different, and I can't find a recording on CD it.
However the rest of the book is good. A number of other interesting Billy Taylor originals as well as some standards. Its worth noting that he uses tenths quite a lot, so if you struggle beyond an octave with your left-hand you'll have to compromise somewhere.
The Book contains:
All the Things You are
Gone with the wind
I Didn't Know What Time It was
I Wish I Knew How...
Make A Joyful Noise (suite of pieces)
A Tune for Howard to Improvise On
Most of these pieces are the versions from his solo Piano album "Billy Taylor: Solo", so you can hear what they should sound like.
In classical terms the pieces range in standard from grade 5 upwards, with the average probably being grade 7. Of course this is a book of jazz transcriptions so reading the notes won't make it sound right unless you have a feel for the music.
*Subsequently I found you can get the famous version of "I Wish I Knew...." from a number of digital sheet music sites, and I now have a copy.
