Looking for some Euphonium sheet music

[dwaskew]

The Finnish Music information centre is a good place to start.
http://www.fimic.fi/" target="_blank The Kohlenberg is listed on there (after a little searching)
and, I believe it's "Koskinen". I didn't see that work listed, but the composer is definitely on there. There -may- be a link to contact composers, but I didn't go that deep.

For future research, there is also a Swedish information centre, too, http://www.stim.se" target="_blank, as well as http://www.musicfromnorway.com" target="_blank, although the last one is more oriented towards recordings it appears.
