Raymond,
I am not sure about all of that, but I can say this:
I am not sure why Mr. Pattison and other so-called teachers continually fail to mention the pivotal role of blotter acid and a bag of good Mexican homegrown in the creation of the most sophisticated song lyrics.
For example, if you listen hermeneutically to the phenomenal demographic exegesis in Hotel California, you will almost certainly detect a profound understanding of psilocybin and the counterpoint enhancing contributions of some A+ grade THC.
To miss the importance of these natural enhancers, along with the counterbalancing after effects of bourbon or whiskey consumed in the largest possible quantities, is to miss the very essence of artistic indulgence itself, and the supreme recklessness and abandonment of logic that has always led to the most interesting chord progressions and melodies in modern music.
I must protest this boldly and state that I have no more time for this type of balderdash.
Thank you, and steady on.
Assisted writing?
Having watched & participated in some of the man's teaching all I can offer is that he likes uniformity, rules, uniformity, structures, uniformity and things his way. There're a few Berserkly "YouTubers" who pontificate on making music or how music works. Some like Henning Pauly of HP42 are so obsessed with "the rules" that their music sounds like it's built from a join the dots system while others like Adam Neely find solace in "the Rules" occasionally as balance to challenging them on performance & theoretical levels. Neither appears to dip a finger into the the beaker though.
I used assisted writing techniques, inadvertently, when at college...when a handy dorm wall provided the perfect surface for lyrical conceits after a trip down the frog'n' to the rubberty for a glass of cheer.
