​FULL ORGAN. This term, when standing alone, generally signifies that the chief manual, or Great Organ, is to be used, with all its stops brought into requisition. Sometimes the term is employed in an abbreviated form, and with an affix indicating that a portion only of the stops is to be played upon—as 'Full to Fifteenth.' In the last century the expressions 'Full Organ,' 'Great Organ,' and 'Loud Organ,' were severally used to indicate the chief manual organ.
