1. A system for adaptive demarcation of a selectively defined tonal scale on a musical instrument, comprising:
a set of note actuators, each note actuator being independently excitable to actuate the musical instrument to generate a musical note corresponding thereto, said note actuators respectively corresponding to musical notes collectively spanning at least one musical octave; a scale acquisition portion acquiring a tonal scale characterized at least by a predetermined mode and predetermined key signature, the predetermined key signature identifying one of the musical notes as a root tone component, the predetermined mode denoting a predefined ordered series of tone components beginning with the root tone component, the tone components respectively represented by different musical notes within one musical octave of the root component, the tone components being successively separated in pitch by tonal intervals; a scale delineation portion coupled to said scale acquisition portion, said scale delineation portion adaptively mapping the tone components of the acquired tonal scale to a corresponding subset of said note actuators within at least one musical octave; and, a plurality of marker portions coupled respectively to said set of note actuators, said marker portions being selectively enabled according to the mapping of tone components to visually indicate said subset of note actuators corresponding thereto, wherein visual indication is adaptively maintained for said subset of note actuators pertaining to the acquired tonal scale; wherein said scale acquisition portion is selectively configured for manual or automatic acquisition of the tonal scale, said scale acquisition portion in the automatic acquisition configuration executing on a music sample captured by acoustic sensing to derive a mode and key signature for the tonal scale based on the music sample, said scale acquisition portion in the manual acquisition configuration receiving the predetermined mode and key signature for the tonal scale set by through a user interface; wherein said scale acquisition portion includes a configuration setting unit for selectively setting:
a key signature select parameter identifying the root tone component for the tonal scale;a mode select parameter identifying the ordered series of tone components of the tonal scale with reference to the root tone component thereof;a mode capture parameter for selecting the automatic acquisition configuration for acquiring the tonal scale;a chord indication parameter for selectively enabling a chord indication unit executable to automatically identify each musical chord available for generation using the tone components within the acquired tonal scale, whereby said marker portions are selectively enabled responsive to user selection from the available musical chords for visually indicating corresponding ones of said subset of note actuators;a range setting parameter for selectively disabling said marker portion of each of said note actuators disposed outside a selectively defined musical octave range; and,a note deactivation parameter for selectively disabling any of said note actuators for musical notes excluded from the tonal scale. |
