Music chord generating device and method based on signal triggering

Abstract

The invention provides a music chord generation device and method based on signal triggering, and relates to the technical field of music chord generation. The device comprises a plurality of sensingmodules which are connected with a plurality of strings, detect the real-time state data of each string, and generate a triggering signal, wherein the trigger signal comprises a first number of the sensing module and a second number of the string; a sub-controller which is used for retrieving according to the first serial number and the second serial number and outputting a third serial number ofthe sub-controller and the total serial number of the strings; a master controller which starts timing when starting to work and outputs a timing result when receiving the retrieval result, calculateschords corresponding to the timing results and notes corresponding to the chords, matches a virtual musical instrument according to the total serial number of the strings, and generates a control instruction according to the notes and the virtual musical instrument; and a playing module which is used for playing notes corresponding to the virtual musical instrument according to the control instruction. According to the invention, playing can be carried out by simply shifting the strings, the chord effect of the played music can be kept at any time, and professional playing technologies and skills are not needed.

Description

technical field [0001] The present invention relates to the technical field of music chord generation, in particular to a music chord generation device and method based on signal triggering. Background technique [0002] A chord is a concept in music theory, referring to a group of sounds with a certain interval relationship. Three and more than three tones are combined vertically according to the relationship of three-degree superposition to form a chord. There are usually concepts such as triads (three-tone chords), seventh chords (four-tone chords), and ninth chords, among which common chords are C, Dm, Am, F, G, etc. The chords formed by the relationship of thirds are widely used because the tension between each sound is maintained, the sound is harmonious and full, and it conforms to the natural law of overtones.

Problems solved by technology

[0003] In the prior art, when people use musical instruments to play, taking the guitar as an example, it usually takes a long time to master the pressing of more chords and the switching between chords and chords, and the arrangement of chords for each song often requires It takes a long time to master it proficiently, so it needs a certain reserve of music theory knowledge and the ability to use musical instruments, and those who have not received professional musical instrument training and lack in pitch, rhythm and musical sense cannot play the corresponding musical chords. Therefore, now Some instruments cannot meet the needs of most people
