Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The melody score method and apparatus according to the embodiments of the present application will be described with reference to fig. 1 to 6.

Referring to fig. 1, a schematic flow chart of a melody score method according to an embodiment of the application is shown. As shown in fig. 1, the melody score method may include the steps of:

s101, obtaining a target melody track.

In some possible embodiments, the terminal may acquire the target melody track. Wherein the target melody track may include 16 to 24 melody bars, each melody bar may include at least one musical beat, and each musical beat may include at least one melody note. For example, the target melody track has a beat number of 4/4, which indicates that the score 4 notes are one musical beat, and each melody bar has 4 musical beats; for another example, the target melody track has a beat number of 2/4, which indicates that the score 4 is a musical beat, and each melody bar has 2 musical beats. Only one pitch and duration at a time on the target melody track. The melody in the target melody track can be any one of the commonly used 4/4 beat, 3/4 beat and 2/4 beat, and the melody in the target melody track can be any of the major C, minor C, major G or minor a, etc. The duration of the music beat in the target melody track is within a preset duration range. The preset duration may range from 0.75 seconds to 1 second, that is, the performance speed of the melody in the target melody track is between 60bpm and 80 bpm. bpm is a common term for music and is used to indicate how many beats per minute of music are.

In music, time is divided into equal basic units, and each unit is called a musical beat. The duration of a musical beat is expressed as the duration of a note, and the duration of a musical beat may be quarter note (i.e., a musical beat with quarter note) or half note (a musical beat with half note) or eighth note (a musical beat with eighth note). The duration of a musical beat is a relative time concept, such as when the performance tempo of a musical piece is 60bpm (representing 60 musical beats per minute), the time taken by each musical beat is 1 second, and half of the musical beats are 0.5 seconds; when the performance tempo is 120bpm, the time of each music beat is 0.5 seconds, half the music beats are 0.25 seconds, and so on.

In some possible embodiments, the terminal may obtain an original melody file including a plurality of melody notes, and may obtain at least one target melody note from the plurality of melody notes in the original melody file, where the target melody note may be used to represent an even number of melody notes in the original melody file, such as a 2 nd melody note, a 4 th melody note, a 6 th melody note, and a 2 m-th melody note, where m may be an integer, and where m may be a value ranging from 1 to half the number of melody notes. The original melody file may include a start time and an end time of each melody note. The terminal may advance the start time of each target melody note of the at least one target melody note by a target time threshold corresponding to each target melody note, and may advance the end time of a preceding melody note of each target melody note by the target time threshold to obtain the target melody file. The terminal may acquire the target melody track from the target melody file. According to the embodiment of the application, the time value of the melody in the original melody file (the starting time of the target melody note is advanced) is adjusted, and a random factor (the target time threshold value) is introduced into the time value of the melody, so that the unstable feeling of the music can be increased, and the unstable feeling of the melody in the target melody track can be increased.

The original melody file may be a single-tone melody file in a musical instrument digital interface (musical instrument digital interface, MIDI) format, which may represent a melody file having only one pitch and duration at the same time. The target time threshold may include 1/2 (start [ n ] -start [ n-1 ]), 1/3 (start [ n ] -start [ n-1 ]), or 1/4 (start [ n ] -start [ n-1 ]), which may be used to represent a start time point of the nth melody note, and the start [ n-1] may be used to represent a start time point of the nth-1 melody note, and n may be an even number greater than or equal to 2.

For example, take the 2 nd and 4 th melody notes in the original melody file as examples. The terminal advances the start time of the 2 nd melody note (target melody note) in the original melody file by any one value of 1/2 (start [ n ] -start [ n-1 ]), 1/3 (start [ n ] -start [ n-1 ]), or 1/4 (start [ n ] -start [ n-1 ]), such as 1/3 (start [ n ] -start [ n-1 ]), advances the end time of the previous melody note (i.e., 1 st melody note) of the 2 nd melody note by 1/3 (start [2] -start [1 ]), wherein start [2] represents the start time of the 2 nd melody note, and start [1] represents the start time of the 1 st melody note. The terminal advances the start time of the 4 th melody note (target melody note) in the original melody file by any one value of 1/2 (start [ n ] -start [ n-1 ]), 1/3 (start [ n ] -start [ n-1 ]), or 1/4 (start [ n ] -start [ n-1 ]), such as 1/2 (start [4] -start [3 ]), advances the end time of the previous melody note (i.e., 3 rd melody note) of the 4 th melody note by 1/2 (start [4] -start [3 ]), wherein start [4] represents the start time of the 4 th melody note, and start [3] represents the start time of the 3 rd melody note.

In some possible embodiments, the terminal may acquire an original melody file, and may acquire a speed parameter (i.e., performance speed) of the melody from the original melody file. The terminal may detect whether the value of the speed parameter is within a preset speed range. If the value of the speed parameter of the melody in the original melody file is not in the preset speed range, the value of the speed parameter can be adjusted to be a target speed value in the speed range, so that a target melody file is obtained. The terminal may acquire the target melody track from the target melody file. Since the time in music is divided into equal basic units, the duration of the beat of the music in the target melody file is 60 seconds (i.e., one minute) divided by the quotient of the target tempo value. For example, if the target tempo value is 70bpm, the duration of the music beat in the target melody file is 60/70=6/7 seconds. The predetermined speed range may be between 60bpm and 80 bpm.

In some possible embodiments, the terminal may acquire an original melody file and may acquire the speed parameter of the melody from the original melody file. The terminal may detect whether the value of the speed parameter is within a preset speed range. If the value of the speed parameter of the melody in the original melody file is not within the preset speed range, the value of the speed parameter can be adjusted to be a target speed value within the speed range. The terminal may acquire at least one target melody note from among a plurality of melody notes of the original melody file, the target melody note being used to represent even melody notes in the original melody file, and the original melody file may include a start time and an end time of each melody note. The terminal may advance the start time of each target melody note of the at least one target melody note by a target time threshold corresponding to each target melody note, and may advance the end time of a preceding melody note of each target melody note by the target time threshold to obtain the target melody file. The terminal may acquire the target melody track from the target melody file.

S102, determining the music beat duration of the first music track according to the duration of the music beats in the target melody track.

In some possible embodiments, the terminal may obtain the duration of the music beat in the target melody track, and may use the duration of the music beat in the target melody track as the duration of the music beat of the first music track, and may indicate that the speed parameter of the target melody track is the same as the speed parameter of the first music track. For example, the duration of the music beat in the target melody track is 6/7 seconds, and then the duration of the music beat of the first music track is 6/7 seconds. The first musical score track may be a cello track, and the cello track is the same as the target melody track in number of bars and number of beats.

S103, mapping the pitch of the reference melody notes of each music beat in the target melody track to obtain the first pitch corresponding to each music beat in the target melody track based on the mapping relation between the affiliated gamut and the first gamut of the target melody track, generating first tension atmosphere score contents corresponding to each music beat according to the first pitch corresponding to each music beat, and writing the first tension atmosphere score contents corresponding to each music beat into the corresponding score beats of the first score track based on the score beat time length of the first score track.

In some possible embodiments, the terminal may obtain the reference melody notes for each musical beat in the target melody track. The reference melody note may be the first melody note in each musical beat or the first melody note in a musical beat preceding the musical beat. If the first melody note of a certain music beat is a rest, determining the first melody note of the previous music beat of the music beat as a reference melody note of the music beat; if the first melody note of the music beat is not a rest, the first melody note of the music beat is determined as a reference melody note of the music beat. The terminal may obtain a mapping relationship between the gamut of the target melody track and the first gamut of the first musical score, and may map, according to the mapping relationship, pitches of the reference melody notes of each music beat in the target melody track, to obtain first pitches corresponding to each music beat in the target melody track. The terminal may generate first score content corresponding to the respective music tempo according to the first pitch corresponding to the respective music tempo, and the first score content may include pitches near the first pitch corresponding to the respective music tempo, e.g., pitches one tone and/or half tones lower than the first pitch corresponding to the respective music tempo. The terminal may determine, on the first musical score track, a musical score corresponding to each of the musical scores based on the musical score duration of the first musical score track, and may write the first stress musical score content corresponding to each of the musical scores into the corresponding musical score of the first musical score track. The gamut to which the target melody track belongs may be between the small word group G and the small word group G, the first gamut may be a gamut to which a cello track (the first musical note matching track) belongs, and the gamut to which the cello track belongs may be between one octave of the small word group #c and the small word group C.

For example, the terminal detects which pitch in c#cd#def#fg#ga#ab, i.e., cm_pitch [ n ], the first pitch corresponding to each music tempo is. Cm_pitch [ n ] represents the first pitch corresponding to the nth music beat in the target melody track. Assuming cm_pitch [3] is E, the first stress score corresponding to the 3 rd music tempo may be at least 2 pitches in D, # D, E, F. Assuming that the length of the dubbing beat of the cello track is 6/7 seconds, 0 to 6/7 seconds represents the 1 st dubbing beat, 6/7 seconds to 12/7 seconds represents the 2 nd dubbing beat, and so on. The terminal determines the 3 rd beat of the music corresponding to the 3 rd beat of the music, i.e., between 12/7 seconds and 18/7 seconds, on the cello track based on the beat duration of the cello track. The terminal writes the first strenuous music content (e.g., # D and E) corresponding to the 3 rd music tempo of the violin track, i.e., between 12/7 seconds and 18/7 seconds of the violin track.

S104, combining the target melody track and the first musical score track written with the first tension musical score content to obtain and output a musical score file of the target melody track.

In some possible embodiments, the terminal may combine the target melody track with the first musical score track (violin track) written with the first stressful musical score content according to the evolution relationship of time, to obtain a musical score file, and output the musical score file in MIDI format. The score file may include the main melody in the target melody track. For example, at time t, the target melody track and the cello track simultaneously emit sounds each at time t. According to the embodiment of the application, the music content of the tension atmosphere is written in the violin sound track to generate the accelerated listening feeling, and the violin sound track and the target melody sound track are combined and output, so that the tension feeling of music can be increased, melody music which is not limited by the level of a music distributor is realized, a music file for creating the tension atmosphere is obtained, and meanwhile, the music is more harmonious and real.

In the embodiment of the application, a terminal determines the soundtrack duration of a first soundtrack according to the soundtrack duration of a target melody in the target melody track, maps the pitch of a reference melody note of each music beat in the target melody track to obtain the first pitch corresponding to each music beat in the target melody track based on the mapping relation between the affiliated gamut and the first gamut of the target melody track, generates first tone content of a tone in tension corresponding to each music beat according to the first pitch corresponding to each music beat, writes the first tone content of a tone in tension corresponding to each music beat in the corresponding soundtrack of the first soundtrack based on the soundtrack duration of the first soundtrack, combines the target melody track with the first soundtrack written in the first tone content of the first soundtrack, and obtains and outputs the soundfile of the target melody track. The melody score not limited by the level of the score partner can be realized, and the score file for creating a tension atmosphere is obtained, so that the music is more harmonious and real.

Referring to fig. 2, another schematic flowchart of the melody score method according to the embodiment of the application is shown. As shown in fig. 2, the melody score method may include the steps of:

S201, obtaining a target melody track.

The terminal may acquire the number of measure of the whirl in the target melody track and may divide the number of measure into at least 2 development stages. The at least 2 development stages can be equally divided or divided proportionally. For example, if the number of bars is 18, the number of bars is divided into 3 development stages uniformly, the first development stage is 0 to 6 bars, the second development stage is 7 to 12 bars, and the third development stage is 13 to 18 bars; if the number of bars is divided into 3 development stages in proportion (e.g., 1:2:3), the first development stage is 0 to 3 bars, the second development stage is 4 to 9 bars, and the third development stage is 10 to 18 bars.
