Step 305, selects instruction in response to chord, and the chord selected trend is defined as target chord.
Step 306, according to the chord transformation relation pre-seted, is transformed to target chord by chord to be transformed.
Illustratively, described chord transformation relation can adopt the form of list, such as pre-build chord map table, in this chord map table, record has the note corresponding relation between multiple chord, and wherein this relation may include that the note in the i-th list item belonging to the first chord is corresponding with the note in the i-th list item of the second chord；Wherein, described first chord is any one chord in described chord map table, and described second chord is any one chord in described chord map table except described first chord；Wherein i is non-zero natural number, and i < n, n is the list item sum of each chord in described chord map table.
Wherein, the note of above-mentioned chord includes sound and unessential note in chord, generally in a melody, each trifle correspond to a chord, but the note in this trifle be not necessarily all this chord chord in sound, in chord, sound refers to three notes constituting this chord, other notes of this trifle are unessential note, such as, in the chord of C chord, sound is 1,3,5, and 2,4,6,7 is exactly unessential note.Illustratively, as shown in table 1, it is shown that the chord map table of part chord.
Table 1
As shown in table 1, each chord, to there being 7 list items, has a note in each list item, wherein sound in the chord that note is affiliated chord in front 3 list items, and all the other 4 notes are the unessential note of affiliated chord.In table 1, in the chord of chord C, sound is 1,3,5, and in the chord of chord Dm, sound is 2,4,6, and in the chord of chord Em, sound is 3,5,7, by that analogy.Wherein, the 1-7 in table represents seven sounds of duo, ruai, mi, fa, sou, la, xi respectively.
Therefore, chord to be transformed is transformed to target chord may include that
First, the note corresponding relation between the multiple chords recorded in described chord map table determines the note corresponding relation between chord to be transformed and target chord.
Secondly, according to the note corresponding relation between chord to be transformed and target chord, chord to be transformed is transformed to target chord.
In song spring, one section of melody corresponding to the lyrics " if having a day " is that (note is C chord: 5,6,1,2,3), if to become F chord.The note corresponding relation then recorded according to table 1 can carry out such as down conversion:
In C chord 5 are changed to 1 in F chord；
In C chord 6 are changed to 2 in F chord；
In C chord 1 is changed to 4 in F chord；
In C chord 2 are changed to 5 in F chord；
In C chord 3 are changed to 6 in F chord.
Thus, " if having one day " (note: 5,6,1,2,3) this section of melody of C chord has just become F chord (note: 1,2,4,5,6).
Chord for target melody moves towards, chord in chord trend is carried out such as up conversion by chord order in then can moving towards according to its chord successively, such as, the chord trend of hypothetical target chord is C-F-C-F, if being transformed to F-G-Em-Am, then C, F, C, F in chord trend in target melody (or can also be) successively is become F, G, Em, Am according to above-mentioned method by the corresponding relation being referred to table 1 simultaneously.
Or, in another kind of implementation, above-mentioned chord map table can generate by the following method:
