How do you find the notes on the staff? The treble clef and bass clef are two symbols commonly found at the beginning of every piece of music (written for piano). It is important to know these clefs as they tell you where your pitches are. And the names of notes on the lines and spaces change according to which clef is placed before them. Once you learn the treble and bass clefs, F line, G Line, and Middle C Line you can find any note on the staff!
