Today the main difference between Western and Eastern neumes is that Eastern notation symbols are \"differential\" rather than absolute, i.e., they indicate pitch steps (rising, falling or at the same step), and the musicians know to deduce correctly, from the score and the note they are singing presently, which correct interval is meant. These step symbols themselves, or better \"phonic neumes\", resemble brush strokes and are colloquially called gántzoi ('hooks') in modern Greek.
Simplified Music Notation is an alternative form of musical notation designed to make sight-reading easier. It is based on classical staff notation, but incorporates sharps and flats into the shape of the note heads. Notes such as double sharps and double flats are written at the pitch they are actually played at, but preceded by symbols called history signs that show they have been transposed. 076b4e4f54
