#initialize(exercises:, tempo:, degrees:, all_single_degree:, directory_prefix: "") ⇒ Listening

The reason number of exercises is required is because the actual number generated is quite large For three degrees, it’s something like 88C3, but a bit smaller because one you choose 1, you actually exclude some of the 88 other than just itself (i.e. if you chose the b2 degree, you exclude the rest of the b2 degrees too) 2 degrees => 21592 (left it for a while and it seemed to stop at this value) - comparable to 64C2 * 12 = 24192 3 degrees => 252398 (before I stopped it, there was more being generated)
