English: Muto notation is a music notation system based on the Muto music method that indicates one octave with three baselines. Also called 3-line staff.
Muto notation uses three equally spaced horizontal lines with solid lines at the top and bottom and a dotted line in the middle, no clefs or accompaniments, and ranges are indicated by numbers. The 12 notes in one octave have independent note names and positions, with high notes at the top and low notes at the bottom. Also, unlike staff notation, the position of the notehead within one octave remains the same even if the key or range changes.
