Could you emulate this clip in BIAB and if yes how?
Does "you" know theory or not? If "you" knows theory, as soon as the clip started "you" said "This is in C and it's 12 bar blues. So C to F to C to G to F to C." Then "you" heads to the chord chart and puts in a 12 bar blues pattern. Then "you" picks a style and hits generate. And "you" has a song.
However, every "you" has different levels of music comprehension. Can the "you" in question play those blues piano embellishments? This particular "you" heard that this should be played on a heavily phased Wurlitzer piano sound.
Where the rub starts is that a newbie, novice level person, when given that "C to F to C to G to F to C" immediately asks "What's a C?" followed quickly by "What's a bar, since there are 12 of them? Isn't a song longer than that?"
So the answer is yes, anything can be created with BIAB (in my case Real Band, as I have still never booted up BIAB). It isn't going to sound exactly like what you are copying, but why do you want to? If that is the end game, you can buy karaoke tracks and just sing over them. The shortest of shortcuts.
From Merriam-Webster:
Definition of musician: a composer, conductor, or performer of music
Composer of music.
I'll stop talking now.
Oh, PS. The example clip you have posted, a standard 12 bar clip, immediately brought to mind the Paul Butterfield Blues Band playing Walkin' Blues, though they did it in A. With one of the greats on guitar, Mike Bloomfield. Sadly he dies at just 38 under quite dubious circumstances, and there has never been a concrete explanation of how he died. He was found dead behind the wheel of his car with all 4 doors locked. One theory is that he died from a drug overdose and was driven to where the car was found by someone who then thought to lock all 4 doors.
