Listed only by Irwin, who says: An undulating manual stop of 8' composed of two ranks of Dulciana pipes, sometimes voiced especially for the céleste function. Since this is a dull céleste, it is more useful at a slow undulation, which will impair its timbre and the timbres of other stops less. It is usually normal-sharp, but normal-flat is also head in some examples. The sharp-flat pattern does not leave a normal rank free for combination. This sedate, quiet, somewhat colorless stop makes and ideal background and accompaniment tone. Bonavia-Hunt mentions the stop, saying: The earliest form of céleste consists of two dulcianas, which tuned to beat at a slow pulsation rate gave a pleasing effect. This type of céleste was in vogue for many years (often labelled �vox angelica�) until the introduction of string tone of the viol type suggested the string or violes célestes.
