How are pitches placed on the staff?

Pitches are placed on the staff based on their frequency, with each line and space representing a specific musical note. In the treble clef, for example, the lines from bottom to top represent E, G, B, D, and F, while the spaces represent F, A, C, and E. In the bass clef, the lines represent G, B, D, F, and A, and the spaces represent A, C, E, and G. The clef used determines which pitches correspond to which lines and spaces.
