Horns work by blowing air through a mouthpiece into the instrument, where lips and fingers manipulate valves, slides, or keys to change the pitch. Different brass instruments like trumpets use valves, trombones use a slide, and proper technique involves using lips and breath control to produce sound while fingers manipulate the various parts of each instrument. Regular practice is important for improving horn-playing skills.
