[Trombone-l] Extra low valve settings

[Keith Marr]

Occasionally I see valve settings whereby the Gb valve can be tuned down to D. There's a couple of questions I have about that:

1 Why would you do this? The second valve must have a heck of a resistance.

2 With the Gb valve tuned to D what is the result of the combination of both valves. Must be very low and a real lung-burster.

One imagines the possibility of pedal tones down off the bottom of the piano register. (Yes, I know you can do this anyway with false tones - stop showing off!)

Although these are usually custom tuning arrangements for individuals I see the Weril Gagliardi comes with a D crook for the second valve as standard issue.

Enquiring minds need to know.

Cheers!
