Yeah. I got myself a songwriting course and it's certainly not compressed, more like 20 - 30 hours in total length. And those guys do a lot of, let's call it, meandering in the topics. Like, one of the basic topics was time signature and time signature notation. And the basics are somewhat simple indeed, but after a minute or two, there's a detour into why german Volksmusik is different about on- and off-beats, and later on there was a detour into irish music and shanteys. This very much reminds me of some of the more advanced university classes - very much stringent about a topic, but entirely ready to look at the flowers left and right.

And while it makes it longer, I find it helps my retention. For one, I have to allocate 40 minutes to an hour for a course part - and that's enough time to make it a conscious decision. And it helps to put new information into context much better, which very much helps retention. Heck, even something like a cat crashing into a keyboard helps remembering things, haha.
