“ The Dominoes, or Tablets are twenty-eight in number, each representing the musical characters or notes- Semibreve, Minim, Crotchet, Quaver, Semiquaver, Demisemiquaver and Semidemisemiquaver.
The figures on the tablets represent the value of the notes compared with the Semibreve which is numbered 1, a Crotchet is 4, meaning four of these particular notes equal one Semibreve, a Semiquaver is 16, because sixteen equal one semibreve, and so on
Two, or four persons may play; if the latter, two become partners against the others. ”
