sentences:  The main findings in relation to the eye–voice span in the reading aloud of language were that (1) a larger span is associated with faster, more skilled readers, (2) a shorter span is associated with greater stimulus-difficulty, and (3) the span appears to vary according to linguistic phrasing.At least eight studies into eye movement in music reading have investigated analogous issues.For example, Jacobsen (1941) measured the average span to the right in the sight singing of melodies as up to two notes for the unskilled and between one and four notes for the skilled, whose faster average tempo in that study raises doubt as to whether skill alone was responsible for this difference.
