Abstract: A method and apparatus for representing musical information as guitar fingerboards dynamically maps the guitar fingerboards to their associated chord notations as the fingerboards are being displayed or printed. The transposition and mapping of the chord symbol onto the fingerboard is accomplished using an array of fingerboard record that represent a chosen set of fretting combinations for a fingerboard and a system for matching the musical information represented by the associated chord with the appropriate fretting combination for that chord.

Abstract: A method for electronically processing and storing musical information involves separating the musical information into a plurality of segments, each representing some portion of a measure, and assigning a sequential time dimension value to each segment. The musical information is also separated into plurality of channels, with each channel representing a sound source and having a sound dimension value assigned to it. The musical information for a given channel and segment is stored in a memory array by associating the musical information corresponding to a given channel and segment with the memory array node specified by the time dimension value and sound dimension value assigned to the given channel and segment.

Abstract: A method and system for transcribing musical information that allows a musician or composer to enter both rhythmic and melodic information directly from a musical instrument, such that the rhythmic information may be entered simultaneously with the entry of melodic information, during a subsequent pass after the entry of melodic information, or automatically either during or after the entry of melodic information using a companded approximation of a single unit of rhythmic information. Rhythmic information is entered as absolute and relative beat unit values from which relative note values (i.e. quarter note, half note) are assigned to the melodic information to create the proper graphic symbols to transcribe the musical information into musical notation or sheet music.
