Iago wanted to seem like a good guy, so he wanted Othello to find out himself that Desdemona is cheating.
She says that “she will go to Mantua and poison him herself”
F# is a Part of the sharp family or whatever you want to call it but any note with # is a sharp, A sharp is raising the notes pitch to make it higher where Bb stands for B flat, Flat meaning to lower the notes pitch.
F# Would be on one end and Bb would be on the other because of the note's octave
the notes shown in the picture are going up raising their volume in pitch making it either higher or lower due to the kind of note it could be.
I don't know if this makes any sense
There are three basic types of relief sculpture: (1) low relief where the sculpture projects only slightly from the background surface; (2) high relief where the sculpture projects at least half or more of its natural circumference from the background, and may in parts be wholly disengaged from the ground, thus approximating sculpture in the round. [Sculptors may also employ middle-relief , a style which falls roughly between the high and low forms]; (3) sunken relief, where the carving is sunk below the level of the surrounding surface and is contained within a sharpely incised contour line that frames it with a powerful line of shadow. The surrounding surface remains untouched, with no projections. Sunken relief carving is found almost exclusively in ancient Egyptian art, although it has also been used in some beautiful small-scale ivory reliefs from India.
