A dominant 7th chord is a major chord with a minor seventh added on top. E# is the major third, four frets above the root. G# is the perfect fifth, seven frets above the root. B is the minor seventh, ten frets above the root.
E# sounds the same as F. It is spelled E# because the third of C# is always a kind of E.
