I was listening to this recording of Berlioz symphony by the French orchestra "Orchestre philharmonique de Radio France".
After having a laugh about the clarinetist suffering from the trumpets (see 41:51), I noticed at 42:53 that all trombone players are playing on trombone without F attachment, meaning (usually) a smaller bore than most F-attachment trombone. I rarely see philharmonic orchestra with these instruments, except for older pieces of course where you could get sackbut-type instruments.
Given that Berlioz is a relatively recent composer (the trombone was well establish at this time) why would the player use these instruments ? They are usually less-round instruments, not perfectly suited for classical setting (at least that is my understanding). I'm pretty sure it is voluntary, but it's not something I can find in other recordings :
- A recording by Frankfurt Radio symphony, playing with F-attachment
- A recording by the French national orchestra, playing with attachment
- A recording by Radio France & Simon Bolivar Youth orchestra of Venezuela (more clearly), all playing with attachment, except one that seems to be an alto trombone at one point
But I also found another recording by Radio France, different conductor, where they still use trombone without F-attachment.
Anyone care to enlighten me?
