Solution Overview

Problem

Traditional asymmetrical keyboards and staff notation systems are complex, leading to confusion in note identification, chord recognition, and transposition due to non-uniform key spacing and accidental usage, making it difficult for musicians to learn and play music effectively.

Innovation Solution

An asymmetrical keyboard layout with consecutively ascending keys of alternating colors and a notation system using a twelve-line staff with alternating lines and spaces, where notes on lines correspond to white keys and those in spaces correspond to black keys, eliminating the need for sharps and flats, and allowing for clear identification of notes and chords.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional asymmetrical keyboard layout with 7 uniquely named notes per octave is used, then the keyboard maintains conventional design, but note identification and chord recognition become complex and confusing

Engineering Contradiction:
Improvenote identificationVSAvoidkeyboard layout complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent changes the fundamental parameter of note naming from the traditional 7-note system (A-G) to a 12-note system where each key has a unique name (C, C#, D, D#, E, F, F#, G, G#, A, A#, B). This parameter change eliminates the confusion of accidentals and enharmonic equivalents, making note identification straightforward and unambiguous.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies asymmetry by differentiating the visual appearance of white and black keys through color coding (e.g., white keys with one color, black keys with another). This asymmetric treatment of otherwise similar keys (both are just keys producing different pitches) helps users quickly distinguish between them and understand their functional differences in the 12-note system.

Inventive Principle:
Principle #4Asymmetry

2Adaptability or versatility

If accidentals such as sharps and flats are used in traditional notation, then all 12 pitches can be represented, but note names vary for identical pitches depending on the key

Engineering Contradiction:
Improvepitch representationVSAvoidnote name consistency
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent eliminates the accidental system by changing the note naming parameter to include all 12 pitches as unique names. Instead of using C, C#, Db, D, etc. for the same pitch, the system uses a consistent 12-note naming scheme where each pitch has exactly one name, preventing the loss of information about the actual pitch being played.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If traditional staff notation with 5 lines is used, then conventional music notation is maintained, but notes occupy varying positions depending on clef, octave, and accidentals

Engineering Contradiction:
Improvereading musicVSAvoidnotation system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent expands the traditional 5-line staff to a 12-line staff, adding another dimension to the notation system. This dimensional change provides a dedicated position for each of the 12 pitches in the chromatic scale, eliminating the need for accidentals and clef-dependent position variations. Each line and space corresponds to a specific pitch, making reading music more straightforward.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If white keys are assumed to be evenly spaced notes, then the keyboard appears symmetrical, but the actual interval half steps between notes vary between 1 and 2

Engineering Contradiction:
Improvevisual note spacingVSAvoidinterval accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies local quality by giving white and black keys distinct visual characteristics (different colors) to reflect their different roles in the 12-note system. This local differentiation helps users understand that while all keys are equally important, they serve different functions and have different interval relationships, correcting the false impression of uniform spacing.

Inventive Principle:
Principle #3Local quality

AI summary

A music system having an asymmetrical keyboard layout and a notation system and method of using same are disclosed. The music system includes an asymmetrical keyboard layout comprising at least one octave. Each octave includes consecutively ascending keys of consecutively alternating first and second colors, respectively, extending throughout the entirety of each octave. The music system also includes a notation system comprising a staff including consecutively ascending and alternating lines and spaces. The consecutively ascending and alternating lines and spaces correspond to the consecutively ascending keys within each octave, respectively. Notes positioned on the lines correspond to keys having the first color, and notes positioned substantially entirely within the spaces correspond to keys having the second color. Embodiments foster a coherent music system that enables a user to learn, read, manipulate, and play music with great understanding and ease, using the asymmetrical keyboard layout and notation system.
