Description

Music performance method, electronic device, and computer-readable storage medium

technical field

The present invention relates to the field of electronic musical instruments, and more particularly, to a music performance method, an electronic device and a computer-readable storage medium.

Background technique

Sound intensity, pitch, and timbre are the three major elements of musical sound, among which: sound intensity refers to the strength of the main tone in the sound signal, which is the basis for judging musical sound, which is determined by the magnitude of the mechanical wave amplitude (the two are proportional to each other, The larger the amplitude, the more "stronger" the sound, and vice versa, the "weaker"); the pitch refers to the tone, which is determined by the frequency of the mechanical wave (strictly speaking, the fundamental frequency); the timbre refers to the performance of different sounds in terms of waveforms. Different characteristics, the timbre is determined by other bands (such as overtones) of the sound other than the fundamental wave. These bands do not affect the pitch. Usually, different sound generators have different timbres due to their different materials and structures (for example, Pianos, violins and people make different sounds).

As a sounding tool that can cultivate sentiment, musical instrument is an important spiritual property of human beings. There are many kinds of traditional musical instruments, and the structure and timbre are also very different. The sound bodies are basically strings, membranes, springs, plates or metal bodies, such as violins, huqins and stringed instruments, which are all emitted by the vibration of strings. Sound; gongs and plucked instruments produce sound by vibrating metal bodies. Although electric guitars and electric basses also need to be powered on, their sound bodies are still strings, so they are classified as electroacoustic instruments rather than electronic instruments.

In the current society, with the acceleration of life rhythm and the improvement of living standards, more and more people are more inclined to contact with the senses and more direct visual experience. Therefore, the traditional musical instruments are limited by the sound structure and can no longer meet the corresponding requirements. demand.

Electronic musical instruments are musical instruments in which musicians trigger electronic signals by specific means, so that they use electronic synthesis technology or sampling technology to produce sounds through electro-acoustic devices, such as electronic pianos, electric pianos, electronic synthesizers, and electronic drums. Different from traditional musical instruments, the sounding body of electronic musical instruments is composed of a number of electronic components to form oscillators. Through voltage amplification, different frequency changes generate different audio signals, and then power amplification is performed to transmit specific sounds from speakers. And compared with traditional musical instruments, electronic musical instruments are generally not affected by natural climatic conditions, it is only affected by factors such as voltage, current or the quality of electronic components (the possibility of this phenomenon occurring in regular electronic musical instruments is extremely small).

However, whether it is a traditional musical instrument or an electronic musical instrument, it has high requirements on the performer, and the performer often needs to go through systematic training and long-term practice before playing. For example, a piano generally has 88 keys, and each key corresponds to a note. With the addition of a foot pedal, the player needs to skillfully cooperate with 10 fingers and feet when playing a piece of music according to the score; when playing with a violin, the player generally The bow is drawn with the right hand, and the five fingers of the left hand are used to touch different positions on the strings to produce different tones. Although the violin has only three strings, different notes require fingers to touch different positions on the strings, and the touch positions are slightly different. will not be allowed.

In addition, in the current musical instruments, players generally control the sound intensity (loudness) through body movements, and inject emotion into the music. The subtle differences in body movements (including strength) will affect the performance, which is why it is difficult to play musical instruments. Moreover, no matter how the performer practices, no matter how skilled the performance is, body movements cannot fully reflect human emotions, so it is impossible to fully inject emotions into music.

Embodiments of the present invention

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

As shown in FIG. 1, it is a schematic flowchart of a music performance method provided by an embodiment of the present invention. The music performance method can be applied to a smart mobile terminal (such as a mobile phone), a smart bracelet, a smart watch, an earphone or a dedicated electronic device, and Realize personalized music performance. Specifically, the music performance method of this embodiment can be implemented in combination with an application program installed on a smart mobile terminal, smart bracelet, smart watch, earphone or dedicated electronic device, and the method includes:

Step S11: Real-time acquisition of human body characteristic parameters through sensors, the above-mentioned human body characteristic parameters include human movements (such as movements of hands, fingers, feet, head, face, waist, etc.) and/or emotional signs (such as bioelectric waves such as brain waves, temperature, etc.) , pulse, blood pressure and expression, etc.) corresponding electrical signals.

In practical applications, the above sensors include one or more of a touch screen, an acceleration sensor, a force keyboard, a gyroscope, a bioelectric wave sensor, a temperature sensor, a pulse sensor, a blood pressure sensor, a vibration sensor, an image sensor, and a sound pickup. Obtaining human body characteristic parameters through various types of sensors is a conventional technique in the art, and details are not described herein again.

Step S12: Generate sound intensity time value data and note switching point data in real time according to the human body characteristic parameters. As shown in Fig. 3, the above-mentioned sound intensity time value data refers to the sound intensity and the duration of each sound intensity, which can be represented as the curve 31 in Fig. 3, and corresponds to the amplitude of the sound vibration changing with time; The point data refers to the time point at which the switching (note) performance is performed, which can be represented as a straight line 32 perpendicular to the time axis in FIG. 3 , and a switching operation is required when receiving the note switching point data.

For example, when the sensor is worn on the human wrist, the sound intensity time value data generated in this step can be positively correlated with the motion amplitude of the wrist measured by the sensor, such as curve 31 shown in FIG. The movement amplitude is larger than the wrist movement amplitude of other parts, and the corresponding sound intensity time value data is also larger; and the note switching point data generated in this step is also positively correlated with the wrist movement speed measured by the sensor, such as curve 31 shown in Figure 3 , the wrist movement speed of the parts corresponding to serial numbers 7 and 14 is slower than that of other parts, and the interval of the note switching point data at this time is also larger.

Step S13: Generate music data according to the sound intensity time value data, the note switching point data, and the pre-stored note sequence and timbre data, and play the music data, where the note sequence is composed of pitch data of a plurality of notes.

In this embodiment, the note sequence includes a plurality of sequentially arranged notes, which can be input in advance and stored in the storage unit. For example, corresponding to the excerpt music score shown in FIG. 2 , the pre-stored note sequence may be: 11556654433221, and each note corresponds to a pitch (tone). Timbre data is used to represent sound characteristics, such as piano, violin, guzheng, erhu, drum set, etc.

4, in this step, the note sequence and timbre data can be selected from the pre-stored data in advance, and then the selected note sequence and timbre data are compared with the sound intensity time value data and note switching point data generated in real time in step S12. Corresponding music data 51 are sequentially generated and played.

The above music performance method collects human body characteristic parameters through sensors to generate sound intensity time value data and note switching point data, and combines the pre-stored note sequence and timbre data to synthesize music data. With simple practice, everyone can play personalized music. Music, and can achieve the performance of all instruments. It is especially suitable for personalised arrangements and performances of music.

As shown in FIG. 5 , it is a schematic flowchart of generating sound intensity time value data and note switching point data (ie, step S12 ) in the music performance method provided by the embodiment of the present invention. Specifically, when the sensor includes one or more of a touch screen, a pressure sensor, a force keyboard, an acceleration sensor, a vibration sensor and a gyroscope sensor, the above step S12 includes;

Step S121: Convert the human motion into amplitude parameters and time parameters.

For example, when the sensor is a touch screen, the amplitude and speed of the sliding action received by the touch screen are positively correlated with the amplitude parameter, and the speed of the sliding action is positively correlated with the time parameter; when the sensor is one of an acceleration sensor, a vibration sensor and a gyroscope sensor, The detected movement amplitude speed and acceleration are positively correlated with the amplitude parameter, and the duration or duration of the sliding action is positively correlated with the time parameter; when the sensor is a pressure sensor, the detected pressing force and change are positively correlated with the amplitude parameter. Correlation, the detected compression duration or duration is positively correlated with the time parameter.

In particular, when the sensor is a force keyboard, it can confirm the human action according to the pressing force. For example, the force keyboard includes a key and a number of conductive rubber contacts located at different heights below the key. When the key is pressed Among them, there is a time difference between the electrical contact between the keys and different conductive rubber contacts. Since the above time difference is inversely proportional to the movement speed of the keys, and the movement speed of the keys is proportional to the strength of the keys, the pressing force of the keys can be obtained according to the above time difference, and then The human body movement is obtained, and the amplitude parameter and time parameter are generated accordingly. For example, the amplitude parameter is positively related to the pressing force, and the time point when the key is pressed can be used as the time parameter. In addition, the force keyboard can also be realized by electromagnetic induction, that is, the force keyboard includes the keys, the magnets installed on the keys, and the induction coils installed on the printed circuit board. The action of pressing the keys drives the magnets to move, and the magnetic field changes in the induction coils. A current is generated in the current, and the signal strength of the current corresponds to the strength of the button, so as to obtain the motion of the human body, and then generate the amplitude parameter and the time parameter.

Step S122: Generate sound intensity duration data according to the amplitude parameter, and generate note switching point data according to the time parameter. Specifically, the larger the amplitude parameter is, the larger the sound intensity time value parameter is; the larger the time parameter is, the longer the interval of note switching point data is.

In the above manner, the performer can slide on the touch screen (such as the touch screen of a smart mobile terminal), or press or squeeze the electronic device with the pressure sensor, or wear a smart bracelet, a smart watch and wave his arm, or hold a special electronic device By waving your arms, or wearing headphones to shake your head or nod your head, you can play different musical instruments without having musical instrument skills.

In addition, when the sensor includes one or more of a bioelectric wave sensor, an image sensor, and a pickup, changes in bioelectric waves (eg, brain waves) may be detected by the biowave sensor, images (eg, dance moves) may be captured by the image sensor, and picked up by the pickup Sounds (e.g. humming songs), correspondingly, sound intensity duration data and note switching point data can be generated by converting the signal acquired by the image sensor and the signal acquired by the pickup into amplitude parameters and time parameters, such as when the image When the dance action is more intense in the signal collected by the sensor, the larger the amplitude parameter is, the shorter the interval time of the note switching point data; the sound intensity time value data is generated according to the amplitude parameter, and the note switching point data is generated according to the time parameter, specifically , the larger the amplitude parameter, the larger the sound intensity time value parameter; the larger the time parameter, the longer the interval of note switching point data. In the above manner, the performer can perform different musical instruments by means of dance moves or humming songs.

With reference to FIG. 6 , in an embodiment of the present invention, a schematic flowchart of the sound intensity duration data and the note switching point data (ie, step S12 ) may also be generated in the following manner. Specifically, when the sensor includes one or more of a touch screen, a pressure sensor, an acceleration sensor, a vibration sensor, a gyroscope sensor, a bioelectric wave sensor, an image sensor, and a sound pickup, as well as a temperature sensor, a respiration sensor, a blood pressure sensor, and a pulse sensor One or more, the above step S12 includes;

Step S121': Convert the human motion collected by one or more of the touch screen, pressure sensor, acceleration sensor, vibration sensor, gyroscope sensor, bioelectric wave sensor, image sensor and pickup into amplitude parameters and time parameters.

For example, when the sensor is a touch screen, the amplitude of the sliding action received by the touch screen is positively correlated with the amplitude parameter, and the speed of the sliding action is positively correlated with the time parameter; when the sensor is one of an acceleration sensor, a vibration sensor and a gyroscope sensor, its movement The amplitude is positively correlated with the amplitude parameter, and the speed of the sliding action is negatively correlated with the time parameter.

Step S122': Convert the signals collected by one or more of the bioelectric wave sensor, the temperature sensor, the respiration sensor, the blood pressure sensor and the pulse sensor into an amplitude coefficient and a time coefficient.

For example, when the amplitude of the signal generated by the temperature sensor, respiration sensor, and pulse sensor is larger, the amplitude coefficient is larger. When the temperature signal generated by the temperature sensor is larger, the amplitude coefficient and time coefficient are larger; when the blood pressure sensor generates a larger blood pressure signal, the amplitude coefficient and time coefficient are larger.

Step S123': Generate sound intensity time value data according to the amplitude parameter and the amplitude coefficient, and generate note switching point data according to the time parameter and the time coefficient.

In this step, the product of the amplitude parameter and the amplitude coefficient can be used as the new amplitude parameter, the time parameter and the time coefficient can be used as the new time parameter, and the sound intensity can be generated with the new amplitude parameter and the new time parameter Duration data and note switching point data.

Through the above methods, the feelings of different people in different environments and at different times can be integrated into the music played, so as to express and interpret the music to the greatest extent, and realize the personalized music performance of each person.

As shown in FIG. 7 , it is a schematic flowchart of generating and playing music data (ie, step S13 ) in the music performance method provided by the embodiment of the present invention. This step S13 includes:

Step S131: Read the pre-stored timbre data and the note sequence, and generate a note playing sequence according to the note sequence.

Specifically, reading the pre-stored timbre data and the note sequence refers to writing the timbre data and the note sequence of the storage unit into the buffer, and generating the note playing sequence may create a queue including the note sequence in the buffer.

Step S132: Take out the foremost note from the note playing sequence, and convert the note into pitch data.

Step S133: Generate and play music data at the current time according to the timbre data, pitch data and the sound intensity time value data at the current time (generated in step S12) until the performance of one note is completed.

Step S134: when receiving the note switching point signal (generated in step S12), delete the current note from the note playback sequence (for example, when the note playback sequence is a queue including a note sequence, move the pointer of the starting position of the queue to the left. move one note), and determine if the note play sequence is empty. When the note playing sequence is not empty, return to step S132 to perform the next note playing until the note playing sequence is empty.
