A method and system of teaching and / or studying music theory and for aiding the practice of musical instruments according to the integration of the color spectrum with notes of the circle of fifths and rearrangement of those notes into the musical chromatic scale. This rearrangement is accomplished by rotating either set of notes (spaced at whole-tone intervals) in the circle of fifths by 180 degrees. The musical chromatic scale arrangement of colors is then applied to various instruments. Diagrams representing the various note / color patterns as they appear on the various color-coded instruments are also provided. Scale and / or chord charts or diagrams for various instruments are also provided. The inventive color code is also applied to tablature, as well as to inventive forms of music notation.

Despite many practical limitations imposed by mobile device platforms and application execution environments, vocal musical performances may be captured and continuously pitch-corrected for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured on mobile devices in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at a portable computing device (such as a mobile phone, personal digital assistant, laptop computer, notebook computer, pad-type computer or netbook) in accord with pitch correction settings. In some cases, pitch correction settings include a score-coded melody and / or harmonies supplied with, or for association with, the lyrics and backing tracks. Harmonies notes or chords may be coded as explicit targets or relative to the score coded melody or even actual pitches sounded by a vocalist, if desired.

The invention provides scoring a performance of a guitar part in a rhythm-action game. It operates in the context of a video game platform in communication with a display and a controller and involves receiving an input performance from the controller including at least one input chord note, each input chord note including an input string value corresponding to a struck string and an input fret value associated with the input string value. Then, a reference performance is provided, which includes at least two reference chord notes to be input at a target time, each reference chord note including a reference string value and a reference fret value associated with the reference string value. Then, a degree of matching is determined between the input performance and the reference performance, and a score is assigned to the input performance based on the degree of matching.

The invention discloses a method for preparing a chord violin, by which various chords can be played. For the conventional chord musical instrument of which a signal string is used for playing, a special secondary string is arranged beside a primary string of the conventional chord musical instrument, so that the single string in changed to be a group of strings, and the conventional chord musical instrument is changed into the chord violin by which a plurality of strings can give out sound simultaneously and chords can be played conveniently. For example, a special secondary string is arranged beside a primary string of the conventional violin, the single string is changed into two strings in a group, so that when the violin is drawn, the two strings can give out sound simultaneously; and when pitches of the primary string and the secondary string are adjusted to be equal to each other, the violin can generate the effect which is like the effects of two violins, the sound is uniform, the tone colors are same, and the efficiency of bands is improved. A method for playing the chord violin is the same as that of playing the conventional violin, so that a player only needs to think how to play the primary string because the dubbing of the secondary string is automatically generated. If a learner wants to learn how to play violin by using the conventional chord musical instrument, only the primary string is required to be arranged on the cord violin.
