That would be a horizontal line melody

I'd say $$[(x,y)\in\mathbb{R^2}:x=c_1,c_2 \leq y \leq c_3]$$

Which stands for, x and y can both be any real number for which x is equal to c1 and y varies between c2 and c3

It may seem a bit weird to say x is any real number for which it is equal to c1, but it's only an indicator for the type of values we are looking at (integers, complex numbers, postive values, etc.)
