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.
Claims15
A musical keyboard split into two bisymmetrical manuals, comprising:
- a first manual for keyboard fingering by a first hand of a user, comprising a first plurality of keys activating a standard pitch progression increasing in pitch from left to right;
- a second manual for keyboard fingering by a second hand of a user, spilt from said first manual, comprising a second plurality of keys activating a standard pitch progression increasing in pitch from right to left;
- wherein:
- said keyboard fingering for the first hand applied to said first manual is exactly the same as said keyboard fingering for the second hand applied to said second manual.
A sheet music system, comprising:
- a staff system comprising six lines and six spaces in which:
- each said space represents one of the members of a lower key character set;
- and
- each said line represents one of the members of a raised key character set;
- wherein an associated musical keyboard split into two bisymmetrical manuals to be played using said sheet music system comprises:
- a first manual for keyboard fingering by a first hand of a user, comprising a first plurality of keys activating a standard pitch progression increasing in pitch from left to right;
- a second manual for keyboard fingering by a second hand of a user, spilt from said first manual, comprising a second plurality of keys activating a standard pitch progression increasing in pitch from right to left;
- said keys comprising two different heights, namely, a lower height and a raised height;
- and
- for each manual, said keys alternating key-by-key, between said lower height and said raised height;
- wherein:
- said keyboard fingering for the first hand applied to said first manual is exactly the same as said keyboard fingering for the second hand applied to said second manual;
- for any octave in any key, the twelve tones of said octave comprise, in key-by-key alternation, six lower height and six raised height keys;
- said lower key character set comprises six characters assigned only to the lower-height set of six keys within an octave;
- said raised key character set comprises six characters different from said lower key character set, assigned only to the raised-height set of six keys within an octave;
- and
- said character assignments are repeated for each different octave.
