Abstract

A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

Claims

1. A music composition, editing, and playback system comprising:

a processor and one or more input/output devices including a display;

the processor for executing a computer readable code for music composition, editing, and playback;

musical notes and chords are visualized in one or more loti, each loti including an octave of notes;

each chord visualization

derived from one or more of a group of seven base vector triads, has a particular polygonal shape with a particular computer determined hue, and

differs from visualizations of other chords for at least one of a different shape or a different hue;

visualizations of musical rhythms created by aggregation of plural ones of the visualized notes and chords in a time circle;

a time circle circumference equal to a particular musical distance and a time marker for moving around the circle;

the aggregation of notes and chords visualized in the time circle in accordance with a user selected rate or scale of the time marker; and

,

a display of one or more harmony parameterized curves filled with one or more chords constructed from normal starbursts and indicative of the octave(s) spanned by the one or more chords, the harmony parameterized curves filled with the one or more chords being transformed to determine at least a portion of a corresponding musical work that is displayed in musical staff notation.

2. A method of creating colorations for three note chords, the method comprising the steps of:

selecting a first set of CIECAM02 environmental parameters including adaptation, surrounding lighting, background luminance, and white point;

after the environmental parameters are selected, selecting a second set of CIECAM02 parameters including lightness and chroma;

displaying a CIECAM02 hue wheel parameterized by lightness and chroma;

in a default interval color selection, locating six substantially equally spaced roundels on the hue wheel, each roundel identifying a different interval color;

providing a roundel or hue wheel adjustor enabling a user to relocate the roundels on the hue wheel for adjusting interval colors;

selecting sets of interval colors for mixing to produce chord coloration for symmetric chord pairs, asymmetric chords, and corresponding colors for chord inversions;

verifying that the chord colors when mapped from a CIELUV color space to a CIECAM02 color space are in gamut;

for “

n”

octaves defining (n×

12) notes, setting a first lightness for the lowest frequency note and a second lightness for the highest frequency note, the intermediate notes being spaced by equal frequency increments;

for each represented note, determining a chroma value that assures the note is displayable for all hues;

varying hue to represent different inversions of a chord;

varying lightness to indicate note frequency; and

,

from the collection of three note chords inherent in the “

n”

octaves, selecting and displaying an image of the chord that is colored in accordance with the above steps.

3. A method of composing a rhythm using geometric shapes, the method comprising the steps of:

providing a library of planar geometric shapes, each shape having n vertices and each vertex of the shape associated with a musical voice;

composing a first rhythmic song layer including four rhythmic verses wherein

each verse includes four phrase sets and is represented by four phrase set circles embedded in a verse circle,

each phrase set includes four phrases and is represented by four phrase circles embedded in a phrase set circle, and,

each phrase includes four beats and is represented by a selected library shape embedded in a phrase circle;

ordering the verses in a selected verse sequence v1-v4;

ordering the phrase sets within each verse in a selected verse-phrase set sequence ps1-ps4;

ordering the phrases within each phrase set in a selected verse-phrase set-phrase sequence p1-p4;

ordering the vertices within each phrase in a selected verse-phrase set-phrase-vertex sequence vx1-vxn;

playing the song layer by sounding the voice of each vertex in order, beginning with (v 1, ps 1, p I, vx1) and ending with (v4, ps4, p4, vxn).

4. The method of composing a rhythm of claim 3 further comprising the step of using the distance between adjacent vertices to indicate the time between sounding the voices of the adjacent vertices.

5. The method of composing a rhythm of claim 4 further comprising the step of sounding the voice of a vertex for a time period indicated at least in part by an out-of-plane projection extending from the vertex.

6. A loop selection method including visualization of a rhythmic structure of a musical composition on a touch screen device, the method comprising the steps of:

providing a sound recording of a musical work, the musical work having an underlying rhythm identifiable by events in the recording;

transforming the sound recording into an event recording that chronologically marks the initiation of each event such that the time span between successive events may be compared;

selecting a portion of the recording including a sequence of events;

displaying a shape circle;

mapping the events in the sequence of events to corresponding locations around the perimeter of a shape circle such that

the mapped events take the same order around the shape circle perimeter as in the sequence,

locations of adjacent mapped events are indicative of the time span between the corresponding events in the sequence of events, and

the sum of the time spans between mapped events is indicative of the time span of the selected recording portion;

visualizing the rhythmic structure of the musical composition by fitting one or more polygons to the mapped events such that polygon vertices coincide with mapped events.

7. The loop selection method of claim 6 wherein first and second polygons are fitted to first and second sets of mapped events and the touch screen is used to rotate the first polygon relative to the second polygon to vary the timing between mapped events.

8. The loop selection method of claim 7 wherein timing changes made with the touch screen result in corresponding timing changes in the event recording.
