Abstract
Novel shapes and interrelationships of interreactive domains for wholetone musical selection devices such as keyboards or other user interface medium are described. Chromatic glissandos are allowed on these devices. Operator choice for ascending or descending one finger slurs using any one of the twelve per octave fingerkeys as slur instigator or slur receptor is optimized. Novel one digit multiple pitch slurs numbering three or four pitches are acheived.
Claims20
A key entity for the motile shaft of a musical keyboard,
- said key entity with an upper surface of a size and substance suitable for tactile engagement with the fingers of an operator,
- said key entity longitudinally greater in length than in width,
- with a particular end of said key entity having a single domain of greater width than the width of a second domain of a second end of said key entity,
- said width of said second domain less than one half of said greater width of said first domain,
- said second end centrally located relative to said particular end, such that a longitudinal straight line along the approximate middle of said particular end passes through the approximate longitudinal middle of said second end,
- said particular end and said second end of said key entity interconnected, such that a fingertip of one hand may move back and forth from either of said ends without losing physical contact with said key entity,
- with a first two-dimensional plane established by the majority of said single domain of said particular end occupying a different and distinct plane than a second two-dimensional plane established by the majority of said second domain of said second end of said key entity.
A two dimensional display medium subdivided into a plurality of interactive domains, together with sensing electronic interface means, said interface means configured in common fashion to recognize and respond to operator selection of said domains for the purpose of enabling the command of musical tones,
- a majority of said domains being contained within the confines of a minimum of two types of spatial entities termed front keyed entities and rear keyed entities,
- with a minimum of twelve of said two types of spatial entities alternating in lateral sequence,
- a majority of said front keyed entities each having a minimum of two domains of differing shape,
- said two domains of differing shape distinguished as anterior domains in close proximity to and greater in width than posterior domains,
- said anterior domains laterally aligned as contiguous domains allowing sequential glissandos by operator selection,
- said anterior domains of a size to allow individual selection by said operator,
- said posterior domains greater in length than in width,
- a majority of said rear keyed entities each also having a minimum of two distinct domains of differing shape,
- said two distinct domains of differing shape distinguished as anterior distinct domains in close proximity to and lesser in width than posterior distinct domains,
- said posterior distinct domains laterally aligned as contiguous domains allowing sequential glissandos by operator selection,
- said posterior distinct domains of a size to allow individual selection by said operator,
- said anterior distinct domains greater in length than in width,
- said anterior distinct domains of said rear keyed entities in approximate lateral alignment with said posterior domains of said front keyed entities, said alignment sufficient to empower said operator to trigger a chromatic glissando along the path of said lateral alignment,
- said anterior distinct domains and said posterior domains with sufficient separation between them such that said operator can individually select between them.
