The stave of 4 lines is usually attributed to an Italian Benedictine Monk called Guido of Arezzo (approx. 991-1033). In "Micrologus" a treatise on music notation, he also used the initial letters of a hymn to define musical pitches. These letters were ut, re mi, fa, sol, la. In most countries "Ut" became "Do" and centuries later with the addition of "ti" the system came to be called the sol-fa notation which was taught in many schools.
