Only oil your valves when your valves will not budge.
Oil your valves through the air holes at the bottom of the valves so that you do not have to take them out.
Hold/support the trumpet with your left hand and play it with your right. Push the valves straight down (not at an angle).
** If you cannot practice because the trumpet is too loud, here is a link to a trumpet practice mute. You can find one at a local music store or follow the link above.
Print these out and fill them in to help yourself memorize notes and how to play them!
