I'm just doing it with a series of switches instead of a fingerboard, which we obviously don't have-- Okay. That's fine. That's great.
只是我用的是阀键,代替圆号上很明显没有的指板,好的,很棒
That's the harmonic series that's on that, and what the valves do is they shorten and lengthen that vibrating column of air very much like the cello string on the fingerboard.
这就是圆号上的泛音列,活瓣的作用是增长或减短,空气柱的高度,很像大提琴指板上的弦
