Step 1
Understand that there are different types of tubas based on the number of valves on the instrument. Three and four-valve tubas are the most common. Each valve is connected to corresponding tuning slide.
-
Step 2
Play your tuba and listen as you push down each valve. You can listen for the proper notes that correspond to each valve. Use the tuning slides to change the pitch or to tune each valve.
-
Step 3
Tune the first valve. Push the valve button in while you blow air. As you blow, slowly move the corresponding tuning slide out and listen for the change in pitch. The farther out you pull the tuning slide, the lower or flatter the pitch becomes because your air has more tubing to move through. Bring the slide in to create sharp or high-pitch notes.
-
Step 4
Follow the procedure for the remaining valves until you achieve the right pitch for each valve. If your tuning slides are difficult to move, grease each slide with special grease to lubricate for easy moving.
