Reddit reviews Oscar Peterson - Omnibook: Piano Transcriptions

One thing you can do is look at/for or purchase a transcription of certain artist's playing. Something like this:

https://www.amazon.com/Oscar-Peterson-Omnibook-Piano-Transcriptions/dp/149500774X

I don't think that particular book contains blue in green, but some artist transcription will.

You can also look for it online:

or

But in the end, if you want to learn jazz, then having a real book is the best way to go. You need to learn to voice your chords and play the melody.

Here is an online real book:

And this is Blue in Green from that book.

Happy playing!
