A:  In order to emphasize the DeckFinder's unprecedented language, a system was devised based on four musical notes, or voices. Notes are harmonic, imparting the cooperative, plural, and synergistic nature of song upon the book. A deck which receives one note is referred to as a “jingle”. It is a pack with an identifiable concept, no more - no less. Two notes, deemed a “melody”, are for those decks accompanied by documentation in the form of a book, booklet or web site. A second note is also granted to historical decks for their longevity. Harmonious works display maturity of concept and are given three notes. Four notes, known as a “Symphony”, are reserved for legendary decks which have influenced others in the field, such as the Rider Waite Smith Tarot, which has spawned over thirty clone decks.
