Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Generalized keyboards are musical keyboards with regular, tile-like arrangements usually with rectangular or hexagonal keys, and were developed for performing music in different tunings. They were introduced by Robert Bosanquet in the 1870s, and since the 1960s Erv Wilson has developed new methods of using and implementing them, proposing keyboard layouts and notations for a wide variety of octave-division tuning systems.
