ABSTRACT:
A 2 manual musical keyboard with the pitch progression on one of the manuals reversed. The keys on these manuals are segregated into 2 groups of 2 different heights in the same way as a standard musical keyboard. The key configurations on these manuals have 12 semi-tones linearly distributed across 12 keys of alternating heights. Instead of the traditional 7 lower keys (white) and 5 upper keys (black), this arrangement has 6 lower keys and 6 upper keys. The notation system for this unique keyboard is a dual character set. Six unique characters for the upper keys and six unique characters for the lower keys. The musical staff for this unique keyboard will have six lines assigned to one character set and the six spaces assigned to the other character set.
