Abstract
The modernization of our country has opened a new era, and the “Internet +” national strategy has gone deep into various areas of people’s livelihood. Faced with many changes in the new situation, a variety of emerging information technologies continue to integrate into the classroom, such as Baidu teaching, Whiteboard, IPAD, flipping classroom, and learning space and so on, which makes the teacher’s teaching method and organization form have very big changes. There is a certain “flip” in the classroom indeed. This study explores the connotation and characteristics of music intelligent teaching and the main factors that affect the formation of music teachers’ intelligent teaching under the background of “Internet +” education. In this paper, the related strategies of the formation of wisdom teaching are applied through the design of the auxiliary system, in order to optimize the traditional teaching mode by making full use of the network technology, improve the teaching efficiency, and train more and more music talents for the country.
Introduction
At present, we are in the era of globalization and informationization of the Internet +, and new information technology, such as computer technology, has penetrated into every aspect of our life. With the rapid development of the new technology revolution and its wide application in the field of education, today’s education has been faced with unprecedented opportunities and challenges, and new expectations and requirements have been put forward to teachers’ teaching [1–5]. The concept of the “Internet +” has received wide attention since its inception in 2012. Premier Li Keqiang first put forward the “Internet + program” in the “Government work report” in early 2015, which means that the “Internet +” is lift to the high level of national strategy. In a congratulatory letter to the first International Conference on Educational Information on May 2015, President Xi Jinping pointed out: “in today’s world, science and technology are advancing with each passing day, and the Internet +, cloud computing, big data and other modern information technologies have profoundly changed human thinking, production, life, learning style, and profoundly demonstrated the prospects of world development. In response to the development of information technology, educational reform and innovation have been promoted. To build a network, digitized, individualized and lifelong education system and a learning society in which everyone can learn at everywhere at every time and to cultivate a large number of innovative talents is the common major issue facing mankind. With the advantage of the Internet + resources, music teaching has emerged in the form of Mooc, wechat and other new teaching modes. The related music teaching practice and theory research also develops slowly. The school should reasonably utilize the new music teaching mode under the background of “Internet +”, enrich the classroom content, improve the teaching quality and put forward new requirements, so as to open up a broad road for the development of vocal music teaching in the future [6–14].

Nature of the “Internet +”
“Internet +” is a product based on Internet thinking, and through continuous practice and innovation, it forms a new economic form which represents the crystallization of human wisdom and constantly changes the direction of economic development. Through this platform, the social real economy is continuously injected with the vitality of innovation, reform and development. “Internet +” is not just the simple addition of traditional industries and the Internet, but refers to the new economic form derived from the integration of Internet resources and technologies with traditional industries. This new economic form can make full use of the advantages of the Internet +, so that the utilization of resources can be rationalized and maximized. Thus, traditional industries can better integrate into the Internet, with a new form to drive social and economic development, so as to form the new social and economic development model with Internet as the media. The Internet is affecting our lives all the time, changing our way of life, and providing us with great convenience in the aspects of clothing, food, housing and transportation. Of course, when “Internet +” is penetrated in all areas of our life, education also rides the “Internet +” train to achieve high-speed development, and “Internet + Education” has come to our lives gradually, changing the traditional educational model [15–19].
Research on the wisdom teaching in the context of the Internet +
The researcher generalizes the connotation of “Internet + education” as follows. The first is the Internet technology. The wide application of Internet technology is the symbol of human society entering the information society. Different people have different views on the internet technology, and most of them agree that it contains the following three parts: sensing technology, communication technology and computer technology. The application of these technologies constantly change the traditional education and bring new vitality. The second is with education as the core. “Internet + education” is very different from “education plus Internet”: the former focuses on education, while the latter focuses on the Internet. The third is that the essence lies in decomposition and reconstruction. “Plus” is not a simple physical addition, but is a chemical change. The Internet can be likened to a chemical vessel, decomposing everything into elements, and then regrouping around the Internet to form a new architecture.
Many domestic scholars have different understandings from different angles. Scholars’ definition of the concept of wisdom teaching is biased to the perspective of information technology: wisdom teaching refers to the use of the new generation of information technology to make classroom into a teaching environment full of wisdom, so as to achieve the intelligence, visualization, and high efficiency of pre-class, in-class and after-class teachingy, and finally realize the wisdom generation of students. In this study, the connotation of wisdom teaching is summarized as follows: first, the support of new technology; second, the theoretical basis as the guidance; third, the concept of wisdom education; fourth, the extension of scope of the classroom to pre-class, in-class and after-class; fifth, rich media resources; sixth, the generation of wisdom as the purpose.

MIDI technology research
MIDI is the abbreviation of Musical Instrument Digital Interface, which can be translated as “musical instrument digital interface”. In the 1980s, in order to solve the problem of communication between electro-acoustic instruments, MIDI was proposed, which can be used to realize the communication between computers and musical instruments. It is different from other formats of video and audio files. MIDI not transfers a sound signal, but a series of instructions, such as at what time, at what speed and loudness, and which sound should be released and so on.
(1) MIDI file structure
The file that records the MIDI information is called the MIDI file. The MIDI file in windows is suffixed with “. Mid”. Midi file belongs to the hexadecimal file. This type of file generally has the following basic structure: the structure of the file header + data description. Midi file structure is shown in Table 1. As shown in the table, the MIDI file is composed of two parts: the file header and the track description information, in which an audio track represents a part of the music score.

(2) MIDI event
Events can be classified into note events, controller events and system information events according to large categories. For such events, there is a unified representation structure: category + parameters. State bytes are always greater than or equal to 80 H. Data bytes are always less than 80 H. Thus, it is convenient for differentiation. Table 2 is the event table in MIDI.

WPF Technology is one of Microsoft’s development technologies of the new generation, covering desktop application development, web application development, and mobile application development. It is the main development direction of Microsoft’s development technology over the next decade. WPF is part of.NET Framework3.0 technology. It provides a unified programming model, language, and framework. It really does the job of separating interface designers from developers. Here’s the basic architecture diagram for WPF:
As Microsoft’s newest generation of presentation technologies, WPF is a crowdsourcing technology that combines the best features of a wide range of technologies, such as declarative markup language (HTML), hardware acceleration technology (directx), the development efficiency of Windows Forms and Adobe Flash’s strong support for animation. WPF mainly has the following key technologies: Extensible programming markup language; User control; WPF not only comes with rich controls, but also supports user-defined controls. By inheriting the usercontrol class, developers can develop various kinds of controls according to their own requirements. After creation, it can also be compiled into DLL files for use by other WPF programs. Data binding; It is a mechanism to establish a connection between application UI and business logic. Graphic animation.The powerful function of graphic animation is based on directx technology. With WPF, developers can quickly create sophisticated vector graphics or even complex animations that will be converted into Direct3D objects and rendered by hardware to get better and smoother image quality.
