Note these number os occurrencies: D=32, G=29, A=21, Bb=25, B=25, C=25. This is a Blues in D. Because, we have some elements of Blues scale: The tonic note (D) is more present in the music, the third degree is G. And we have some elements of Bebop Scale: The sequence Bb, B and C have a lot occurrences in these places. In Bebop it's a common thing. So, All Blues is a mix of Blues and Bebop Jazz. Is that right?! ;-)
