My Old Trombone
I played it in high school many eons ago. This is the end of the slide with the bell in bokeh. It's badly tarnished these days with lots of scratches and a few dents. But it still plays (I tried it and I think I may have scared the neighbors). And the spit valve, shown here, is still functional too. :-)
Macro Mondays: "Sound" theme
For any who don't know what a spit valve is, by the way, here's a brief explanation that I found online at a site called wonderopolis.org:
"When you play a brass instrument, your breath will condense in the instrument. There, the water vapor in your breath cools. When this happens, it turns from a gas to a liquid. Then, it sits in the metal tubes of the instrument. This water vapor (some of which is saliva or “spit”) collects in the instrument. If it builds up, it can affect its sound. To remove the water (or “spit”), players open the spit valve—also called the water key."
