I've seen this done -- the flare I think was a funnel.

And for what is that right hand?

Somewhere in URL land there is his lecture in which he makes a brass instrument w/ several meters of tubing, etc.

bc  recorded much of it at a recent NCNAAPT section meeting. (at San Mateo HS)

Brian Holmes and B. Jones are (is?) the same person.

Check the ease of playing and the overtone structure of each setup and compare. It's amazing what the flared bell does.

After reading JC's below I found my DVD.   Brian uses a green garden hose, a red plastic funnel and one of his mouth pieces.

bc

He has charts showing the frequencies w/ and w/o bells, mouth pieces, lead pipes, etc.  and demonstrates.  The bell is a high pass filter.

Showing off his humorous style, Brain performed a Leopold Mozart horn concerto on rubber hose pipes at a Gerard Hoffnung music festival in 1956, trimming the hose to length with garden shears to achieve the correct tuning.
