At first relevant music term in the music establishment is introduced:
Harmony: music develops into multi part by monophonic, and single melody constitutes the lateral aspects of sound, and harmony is then represented vertical aspect.Harmony, melody and rhythm are the three elements of music.Harmony can play the effect of setting off and strengthening expressive force as the accompaniment of melody, makes acoustics abundant, and is full, strengthened the artistic expression and the appeal of music.
Chord: chord is a notion on the music theory, refers to one group of sound of certain interval relation.With the sound more than three and three, by the stacked relation of three degree, in addition combination just becomes chord in the vertical.Notions such as common chords (chords of three sounds), seventh chord (chords of four sounds), ten common chords are arranged usually.
Harmony carries out: the annexation of the chord in certain harmony scope is called harmony and carries out.It has showed the motion state of harmony, embodies mutual relationship, functional cohesion and sound equipment color between the chord, the effect with clear and definite tonality or fuzzy tonality.
Chord series expression: with the series expression chord.As: table 1
Table 1
Transferring the one-level chord as C is the C chord, and the secondary chord is the Dm chord, and three grades of chords are Em chords, and the level Four chord is a chord, and the Pyatyi chord is the G chord, and six grades of chords are Am chords, and seven grades of chords are B-chords
Mode: mode is one group of used in musical composition musical sound as the pitch material, and this group sound is arranged with the scale form in theory, and wherein the different arrangement mode of each sound, different mutual relationships have just constituted different modes.
In music, isolated sound or chord can't be moulded musical image.Link together according to certain relation during the sound that in music, uses.The several sounds (generally being no more than seven) that link together according to certain relation, and be keynote with a sound, an individual system---mode formed.No matter be big the accent or ditty, first sound all be carry weight most, the status is the most stable, is called as keynote or middle hear sounds.Major mode is a keynote with movable do do, and minor is keynote with movable do la.
Tonality: tonality is meant the accurate pitch position at certain mode place.
The beginning to see of staff stave writes on the lifting mark before the bat.These marks are the accurate pitch of expression melody, just " tonality " of music.Exactly, it is the keynote position that indicates each mode.What briefly, tonality referred to is exactly 24 big ditties.
Period: period is the minimal structure that constitutes independent paragraph.The length of period depends on speed, beat and the type of works.
Period is complete happy think of of performance or the complete relatively happy minimal structure of thinking in the musical works, is to be based upon on the single theme, minimum complete musical form.The ingredient of period is a phrase, comes with closing-styled branch mutually between phrase, is unified into organic musical form structure by closing-styled functional relationship again.Period often is made up of several phrases, has the relation that question and answer are echoed between these phrases.Forming period by two or four phrases, is the comparison common phenomena, but also by the period of being made up of three, five or more phrases, or the period of being made up of an independent phrase.The period of homophony style, when statement, development and the happy think of of end, the technique of expression of harmony cuts much ice.Typical characteristics when therefore, the satisfactory termination of harmony and melody is the period end.Tonality when period can end to begin also can end in the termination fully of related key or other tonalities, and the latter is called the modulation period.
Musical form: the version of melody.Tune forms various paragraphs in evolution, according to the regularity that these paragraphs form, be musical form and find out the form with general character.Such as four-part form ABAB, capitalization is represented tune, identical letter represents that promptly content is identical.
Please in conjunction with referring to Fig. 1, the embodiment of the invention provides a kind of harmony preparation method, comprising:
Step 101 receives the harmony stylistic category that the user imports, the corresponding corresponding harmony mode of described harmony stylistic category, harmony Qu Su.
The harmony stylistic category mainly is meant harmony expression of feeling type, as: glad, sad, indignation, dejected, gentle, sentimental, joyful or the like.
Optionally, the harmony stylistic category can also comprise the speed rhythm type.As: fast, faster, at a slow speed, more at a slow speed or the like.As: table 2,
Table 2
Simultaneously, the corresponding corresponding harmony mode of harmony stylistic category, harmony Qu Su.
For example, when the harmony stylistic category is glad type fast, can corresponding harmony mode be major mode, harmony Qu Suwei fast.
Step 102 is determined the type of harmony mode and the value range of described harmony Qu Su according to the harmony style data storehouse of harmony stylistic category and foundation in advance.
Influence two key factors that music emotion embodies, i.e. speed and mode.Based on conclusion and the music music theory of Hevner, the speed of music is divided into following at least four grades, fast promptly, faster, slower and at a slow speed.With glad, the cheerful and light-hearted mood of harmony embodiment faster, harmony slower and at a slow speed embodies sad, sad mood fast;
The initial chord of big accent is the one-level chord in the music theory knowledge, and is in bright and gay colors, happy, positive.The initial chord of ditty is six grades of chords, the color dimness, and melancholy, soft.
Adopted following strategy based on above-mentioned music theory knowledge, promptly embodied glad, cheerful and light-hearted mood with the big harmony of transferring fast or faster, the harmony slower or at a slow speed of ditty embodies sad, sad mood.This strategy is the reference to the user, generally can guarantee user's the correct embodiment of affection need.
Harmony style data storehouse becomes concordance list with the policy development of adopting, and promptly sets up the concordance list of value range of type, the harmony Qu Su of harmony stylistic category and harmony mode.This concordance list has embodied the mapping relations of value range of type, the harmony Qu Su of harmony stylistic category and harmony mode.As, table 3
