I have been playing the trumpet for a few months now so there are many things I still do not know about how to take proper care of my trumpet. I asked a friend on tips to maintain the good quality of my trumpet and he told me to purchase a blue juice valve oil.
I asked him what the valve oil was for, and he told me that it lubricates the moving parts of the valve for brass instruments. She said that there is a tendency for warm moist air blown from the player’s mouth to make the valve stuck if untreated. I immediately went on and bought the valve oil, thanking my friend for the great advice she’s given.
