Intervals are the distances between any two notes. Each interval will have a number - 1, 2, 3, 4, 5, 6, 7, 8. These numbers are the distance between two notes, based upon counting the lines and spaces on the staff.For example, if we count lines and spaces, starting from C and ending on G, we count: C,D,E,F,G = 1,2,3,4,5, Therefore, the interval from C to G is a fifth (5th).
