Description

This application claims the benefit of the Chinese Patent Application "Smart Stringed Instrument and System" filed on Sep. 22, 2014, No. 201410488129.1, the contents of which are incorporated by reference herein in their entirety.

TECHNICAL AREA

The present invention relates to the field of musical instrument, in particular an intelligent stringed instrument and a system.

STATE OF THE ART

The stringed instrument is an important branch of the musical instrument family, in classical music and modern light music almost all lyrical melodies are played with strings. The string instrument has a uniform timbre and a multi-layered expression: the ensemble is high-pitched and passionate, the solo is gentle and graceful; Due to the rich and varied bow shape (shaking, breaking, plucking, jumping, etc.) it is very flexible. The string instrument contains cello, violin, guitar etc.

It is the essence of guitar playing that when pressing a flavor position, a corresponding string is plucked at the same time and different taste positions are combined to different tones. As in 1 is shown, the combination of the taste positions of the AM chord is indicated at 101, and the combination of the taste positions of the C major scale is indicated at 102.

The chords and the scales are the sequences combined by a certain tonal relationship, the combination of which is highly variable. Compiled by [Germany] Norbert Opgenoorth and Jeromy Bessler, the "Encyclopaedia of Guitar Chords", published by Volksmusikverlag, lists more than 4000 frequently used chords. Compiled by [UK] Bradley, the "Blues Guitar Guide Fingerboard Chart" compiled by Jilin Publishing Group Ltd lists more than 40 commonly used guitar scale ladders, each of which derives a flavor position combination of 12 keys. Based on the diverse and complex knowledge, memory and learning are an urgent problem to solve.

The conventional guitar learning is mainly through the professional books, however, the books are heavy and not easy to use, such. For example, the book called "Encyclopaedia of Guitar Chords", the book consists of 144 pages, but the search process is too complicated, so the learning efficiency is not high. With the technical development and the spread of the application of the computer various application programs of the guitars have arisen, such. For example, the well-known Guitar Pro guitar software developed by AROBAS, the pre-set database provides the ability to quickly find chords, scales and electronic guitar sheets, making it extremely easy for learners to learn.

It is the definitive way of displaying the software and books, the taste positions on the paper or screen (as in 2a to 2 B the learner's mode of learning has no significant change, they should first learn the locations of the taste position in the subject matter and then play the appropriate flavor position on the guitar neck, in which process the learners should remember and locate the location of the taste position, so that the learning efficiency is low. For example, a learner learns how to do 102 1 It is discussed whether he can play the scale well in the end, memorizing in the beginning is already a big problem.
