These are just some of my instruments. They have to be oiled a couple of times a year. It keeps them playing better. I'll be oiling others tomorrow after these have been allowed to absorb the oil. First I will swab these out, removing any excess oil and pack them away unless they will be played.
I have two large recorders: a bass in F and a contrabass in C. One is pictured here. The bigger one is on tomorrow's roster. Regular maintenance keeps them playing well.
