I was just watching a video by a professional guitarist and music teacher, and YT musician, called Tommaso Zillio (whose YT videos I often enjoy):
In the video, Tommaso states that he prefers to teach music theory as a 'constructive' approach (whereby learners choose from a set of "tools", such as negative harmony or inversions, to develop a musical 'recipe' for themselves), rather than a 'prescriptive' approach (stating what musicians should do and making value judgements) or a 'descriptive' approach (which Tomasso believes focuses upon the usage by certain musicians of musical ideas).
I can certainly see some merit in Tomasso's argument for a 'constructive' approach (notwithstanding that it is outlined only briefly in this 12min video, and I would need more time and familiarity with it to evaluate further).
But tbh, I also veer very subjectively (and perhaps wrongly?) towards believing (as per the 'prescriptive' approach) that songs which stay in the same key, and particularly C Major, throughout are just dull and unimaginative.
Similarly, I do like to understand the 'descriptive' historical context of musical choices (eg, the development of bass guitar as leading instrument for dub remix 'versions' of late 1960s - early 1970s Jamaican reggae, which combined with drums and textural effects the DJs could then toast over).
So I'm not wholly convinced that this professional music teacher's "constructive" approach is adequate by itself for learning / teaching music theory. However, I do appreciate that my biases might not be shared by other people.
In fairness, this is only a short video so it surely does not encompass all of Tomasso's outlook on music theory.
And as far as I can tell, he never states in the video whether he believes - if only a little bit - in the usefulness of the two different approaches that he has named 'prescriptive' and 'descriptive'. So it is not entirely clear from this short video whether the teacher is strongly opposed to any (as he terms them) 'prescriptive' or 'descriptive' approach merits.
Ultimately, how would you describe your own approach to learning music theory and employing this usefully?
Do you think there is some merit in following the language used by this music teacher to separate music theory into 'prescriptive', 'descriptive' and 'constructive' approaches? Or perhaps this video tutorial is mostly nonsense?
Cheers,
