Hyperbolic plane geometry is also the geometry of saddle surfaces and pseudospherical surfaces, surfaces with a constant negative Gaussian curvature. A modern use of hyperbolic geometry is in the theory of special relativity, particularly Minkowski spacetime and gyrovector space.
It just asks you to write 1 2 3 below each note from 1 through 4. At number 3, add the 3/4 time signature after the clef. At number 4, do the same thing at number 3 but make sure each measure has three beats. it can be easy if you start by writing the 1 2 3 below each note like they shown above.
