When the Saints Go Marching In - in 10 styles
whether we use an arranger or an auto-accompaniment tool such as BIAB it is quite intereting to play a tune in various styles.
Btw, I find it interesting that there were Chinese titles for all the styles except for Bebop and Gospel. I wonder why....

That was amazing !!

... they don't need no freakin' arranger keyboard !!! ... very interesting ...

Thats because they have 4 hands..

Yes, but only two were working at once most of the time ...

I enjoyed the older Jazz pianist more than the classical style played by the younger person. I thought arranger players, too, can have lots fun and be creative in playing a well known tune in various styles. It might take more on the part of the player than the backup, but it may help an anranger player play better and have more fun while working with and not against the machine.
