Good morning Klaus, the better & technical correct description of the springs on modern horns is (like said by James Maddrey)
"helical spring" but "spiral spring" is correct as well. Regarding "clockwork springs": I had old , very old horns in my collection, mostly Viennese, which were equipped with clockwork springs, but clockwork, which can be made tighter or loser. And I remember how cumbersome fixing or replacing a clockwork spring could be. ############################################################################################ Am 14.11.2010 um 19:16 schrieb Klaus Smedegaard Bjerre: > The most common spring type on modern horns is called spiral springs within > the tuba communities.
