Shouldn't a proper analysis of "how many melodies" be interval based rather than on individual notes? In that case there would be many fewer potential melodies.

Shouldn't a proper analysis of "how many melodies" be interval based rather than on individual notes? In that case there would be many fewer potential melodies. In an interval based analysis, a B to an A would be the same as a C# to a B. Too tired to count past ten but I think there would be 14 in-octave two note intervals, rather than 25. Edit: I stupid, author's terminology confused me with "relative pitch" vs. intervals. And I forgot how to count.
