I like all the names cited for modern composers working in the classical instrumentation palate and agree that they illustrate how the medium is still moving forward. By the way, if you haven’t read **Hallelujah Junction **by **John Adams **- a memoir of his work and life as a composer - I would recommend it.
I also agree with posters who assert that the Beatles will endure - I would add Louis Armstrong, Sinatra, Miles Davis, Elvis, Dylan and a few others, but agree on the basics. And yeah, Rock will be a chapter in the classical music canonin due time…(link to previous thread)
Here’s the question, to me: classical music, in the classic Back-to-Beethoven sense, was about setting up and exploring the deep harmonic structures available with complex instrumentation. Bach’s work defined the basic harmonic structure - his Well-Tempered Clavier was an assertion that Well Tempering was the standard all Western music should adopt. We ended up with Even Tempering but the beginning of this was Bach. His WTC was written to show the how contrapuntal melodic lines could interweave to create deeper harmonic structures - especially if a standard tempering was adopted and keyboards didn’t have to be tuned to specific keys.
Beethoven took deep, complex harmonic structures to a Golden Age extreme. He works the different voices within a symphony the way a master chef combines spices. The fact that the individual voices are so finely wrought within the whole is amazing - each instrument is a fine thread but the full work is a complex tapestry that he controls.
So - in today’s era, what exactly is a deep harmonic structure? I humbly, and provocatively, offer an illustrative counterpoint: The Ramones. The Wall of Sound distortion coming out of Johnny Ramone’s guitar - and I use Wall of Sound consciouslyy, since Tommy Ramone who co-produced their first album was trying to emulate a Phil Spector sound - well, it has deep, harmonic structures. They were using layers of harmonic distortion, not layers of individual instrumentation, but the effect is there. And that is just an extreme example - look at the studio work of the Beatles, again, or Pink Floyd - there’s tons of deep harmonic structure in there.
Or another key musician who stands up to the classics: James Brown. If you don’t appreciate what the Godfather of Soul, the Progenitor of Funk, the Hardest Working Man in Show Business, etc., brings to rhythmic and harmonic complexity, well…
So - what are new and interesting ways to explore music structures and complexity? What about Beck - his mash-up, paste-up songs done with the production team The Dust Brothers are really interesting, too…
Just thinking out loud…
