This is somethimg I do to get more familiar to scales or keys I don´t control well. I improvise with chords and some leads runs, I am not thinking on particuar chords, I just try to fit the chords in the scale pattern to know were it is. What I am thinking about while doing this is the scale position because my objetive with these is to know better where it is. It is also a fun improvisation exsercise and you can get some cool chord progresion ideas from it. The key I´m using in these video is B flat.
