The answer is with a thinned solution of varnish
First one: It would be on Sol
Second one: No. It would be on La. The note is B. And is a Bflat
(I don't know Bass Clef as well. I play Alto Sax, which uses Treble Clef. So please forgive me)
Third one: It would be A flat
Fourth one: It would be C then C flat
(Again, I don't know Bass Clef that well, so don't count on my answers)
