Description

Intelligent stringed instruments and systems

The present application claims priority to Chinese Patent Application No. 201410488129., filed on Sep. 22,,,,,,,,,,,,,,,,,,,,,,,,

Technical field

The invention belongs to the field of musical instruments, and in particular relates to a smart stringed instrument and system.

Background technique

Stringed instruments are an important branch of the instrument family. In classical music and even modern light music, almost all lyric melody is played by the string part. The tone of the stringed instrument is unified, and there are many levels of expressiveness: the ensemble is full of excitement, and the solo is gentle and graceful; it is also agile because of the rich and varied bowing method (shake, broken, dial, jump, etc.). Stringed instruments include cellos, violins, guitars, and more.

The essential behavior of guitar playing is to press the grade, then simultaneously move the corresponding strings, and different grades are combined into different sounds. As shown in Fig. 1, 101 marks the grade combination of the AM chord, and 102 marks the grade combination of the C major scale.

Chords and scales are sequences that are combined in a certain interval relationship, and their combination relationship is ever-changing. Published by the People's Music Publishing House, the author of the "Guitar Chords Daquan" co-edited by [German] Norbert Eugenute and Jerome Bessler lists more than 4,000 commonly used chords. Published by Jilin Publishing Group Co., Ltd., the author is Bradley's "Blues Guitar Scale Fingerboard Illustration", which lists more than 40 common guitar scales, and each of them has 12 kinds of adjustments. Sexual grade combination. Dealing with such a large and complex knowledge, how to remember and learn is an urgent problem.

The traditional way of learning guitar is mainly through professional books, but the books are heavy and inconvenient to use. For example, the "Guitar Chords" mentioned above, the book is 144 pages thick, the search process is too cumbersome and the learning efficiency is not high. With the development of technology and the popularity of computers, various guitar application softwares have emerged. For example, Guitar Pro, a well-known guitar software developed by AROBAS, has achieved fast query of chords, scales and electronic guitar scores through a preset database. The function of the other is greatly convenient for the learner's learning.

Regardless of software or books, the final presentation is to present the taste on paper or on the screen (as shown in Figures 2a-2b). The learner's learning style does not produce essential changes, and it is still the first to learn the taste of the textbook. Place In the position, and then on the guitar neck to find the corresponding grade to play, this process of remembering and looking for the position of the grade makes the learning inefficiency. For example, the learner goes to learn the C major scale shown in 102 in Fig. 1, and does not say whether he can skillfully play the scale. The beginning of the reciting is a big problem.
