Based on Tannhauser, Wagner took himself a bit too seriously.
Wagner, like Dickens, needed an editor.
What was he thinking in the first overture, running that 'crying cat/broken electronic toy' sound from the violins on and on and on and on and on and on and on and on and on and even after adding in some of the wind instruments, the poor strings are still running that six-or-so note whine over and over.
It must last for more than 3 minutes.
Then the music (finally) moves away from it entirely, so it doesnt even serve a purpose of tensing the audience to prepare them for the next scene.
Its the kind of sound that if your kid's toy made it, you'd remove and break said toy within 90 seconds of hearing it first.
If minnesinger contests had music that boring, no wonder they died out. Not a decent song until the last one by Tannhauser, wherein he admits he's "been with" Venus. Blech.
The chorale music was beautiful consistently. And brief
Altoid - curiously strong.
