In music, letter notation is a system of representing a set of pitches, for example, the notes of a scale, by letters. For the complete Western diatonic scale, for example, these would be the letters A-G, possibly with a trailing symbol to indicate a half-step raise--(a sharp ♯), or a half-step lowering (flat, ♭). This is the most common way of specifying a note in speech or in written text in English or German. In some European countries H is used instead of B, and B is used instead of B♭.
Western letter pitch notation has the virtue of identifying discrete pitches, but among its disadvantages are its occasional inability to represent pitches or inflections lying outside those theoretically derived, or (leaving aside chordal and tablature notations) representing the relationship between pitches—e.g., it does not indicate the difference between a whole step and a half step, knowledge of which was so critical to Medieval and Renaissance performers and theorists.

Famous quotes containing the word letter:
“... everybody who is human has something to express. Try not expressing yourself for twenty-four hours and see what happens. You will nearly burst. You will want to write a long letter or draw a picture or sing, or make a dress or a garden.”
—Brenda Ueland (1891–1985)
